At under $50 for the 3D-printed version, this is an essential tool that should be in everyone’s toolkit. It works extremely well for suppressing ground loops and noisy USB outputs from laptops and computers. Be aware that it only sources 100mA o…

Jeremy Tocher

Absolutely unmatched performance and usability. You can’t beat the big knob. I loved my Element III, but had to get the improved IV with resin knob. The menu system is efficient, and I feel like I’m commanding my voyage through sound when I …

Ferdinand Abramowski

Awesome stack, especially for the price.

Clinton Verduin

Part of my first desktop headphone set up. Using this with the Atom DAC+. It has plenty of power for the Sennheiser HD 560S. Sound is clean and clear. I’m loving this little amp.

Victor Shin

The Atom 2 can push my planars at higher volumes with subjectively better/cleaner sound compared to the Topping L30. I’m not hyping night and day difference, but I use the Atom 2 exclusively now.

Jonathan Bayley

Type shit. Ive got 2. Love em both.

Calvin Aichele

When switching to active monitors, the EMI from my high-end computer was audible and distracting. A lot of the most popular options out there for fixing this are either expensive (sometimes upwards of 100 dollars) or inconvenient as they require mod…

Nathan Kwong

Whenever I would connect my DAC/AMP’s USB input to my computer, my active speakers would start buzzing. I put the Synapse in line with the USB connection, and it completely eliminated the buzz!

Marcello Pelusi

This ATOM pre amplifier/headphone amplifier is working well and the sound is really clear. Only two thing do not look right : 1. Without keeping the gain switch on, the sound volume is too poor, so this switch has to stay on the all time. 2 The unit…

Michelle G.

Excited to build my cMoyBB!

Segev Malool

The sound coming thru the DAC is good. However, I was getting a lot of dropouts when connecting to the optical toslink output on my tv (short moments of missing audio, super annoying). I found the guthub repo with the cli tool and an article to down…

Clinton Verduin

This is my first external DAC and after a lot of research I decided on the JDS Labs Atom DAC+. I’m so happy I did. I got it on a closeout deal but would’ve also been happy if it had been full price. I paired it with the Atom Amp+ and a p…

Antoine Drochon

I am super delighted every single day with atom amp+ hevy, it goes into a small Parasound power amp and it makes my B&W sing and zero noise even at very low volume. I’d do that purchase again if I had to.

 

Anatoliy Boyko

Purchased Atom 2 stack recently (really wanted element 3 boosted but was outside of my budget). Atom 2 DAC/AMP are phenomenal quality especially for the price. The stack drives my headphones flawlessly, easy to use and the sound is very clean (not a…

Very pleased. Wondering why it took me so long, lol. Hearing nuance and details I hadn’t heard before.

I’d recommend your gear to everyone.

Mark Williams

Compact, unobtrusive, fed bit-perfect signal from UAPP on my tablet or (via optical) from my TEAC CD transport, audio bliss!! Stellar customer service, and product made in the USA. Truly, the best of everything!

@DrJorts

Bought some new audio gear from @jdslabs and def took advantage of their free custom engraving

@Dmitry49

LOVE the copper ring around the volume knob. The Element by @jdslabs is my new desktop DAC.

Ghazay Almutairi

A very reasonable price, and it helped me connect the mixer and get the full performance of the headphones. I recommend it to everyone.

Weidong Zhang

The amp works very well for my Senheisser HD600. I can’t imagine any headphone in this price range can do a better job than the JDS LABS Atom Amp 2.

Joseph Brown

Great Production, wish I would have known about the Atom Amp 2, would have gone for the all metal body instead. That’s my fualt.

@Autophase

A great sounding combination @TIDAL masters as source, through a @jdslabs #ODAC into @YamahaUK AX392 and finally out of my @TannoyHiFi DC6T Digital really is stunning when done properly

Christian Wetterlin

As a professional music engineer, I need to hear reality in order to judge sound. Both speakers and headphones must give me a true reproduction of the sound I’m working with. Since many years back I rely on JDS products, ATOM AMP+ and EDAC toget…

Jose Schacherer-Jaramillo

I received a new Element IV and it exposed a nasty ground loop. Despite my best efforts, I could not eliminate it, and pulled the trigger on this. A few days later, I am in audio heaven. The Element IV is incredible and the Synapse has silenced the …

Howie Pheltersnatch

Sound quality is way above what I expected at this price range. Great customer service. Made a couple of phone calls to JDS and someone always answered promptly and were very helpful. Highly recommend JDS products.

@MarcoMHanna

Big knob. Big power. Okay, I’ve been a noob my entire life with audio until today. These are powering my HD 700’s and it feels like I’ve experienced music for the first time. @jdslabs you guys make some killer stuff!

Tim M.

JDS does their job well without resorting to Hyperbole to move product out the door. Glad my research led me to this small company with reasonable pricing, solid products.

Alejandro Perez

Had the first gen and finally decided to try out the element iv. Honestly wasn’t expecting a difference but wow, I instantly could tell how much more “crisp” my music felt.

I am amazed by my Element. I don’t feel like I had actually heard my Senn. 6xx headphones before plugging them into this.

Igor G

I needed to move to headphones for Jazz and this combo works well with Sennheiser 6xx headphones. The support was awesome, got answer the same day and all works great!

@NarptGaming

Justine DE LYLLE

I received it super fast even though it comes from the United States and I am in France. Little gem that fits all headphones due to its very low impedance. The sound is super satisfying! I recommend it!

Alessandro Giuliani

I’ve been dealing with an annoying usb buzz for years. Finally found this after ASR review and yes, it works exactly as advertised. Much like the rest of the JDS product ethos: no bs, just works for a reasonable price!

These really do as great a job as any cable with one bonus. The bend memory feature makes for a very clean stack. Well worth the cost when getting the Atom stack.

You simply can’t beat this preamp for the price. The signal is clean and the tone control for lows and highs completely changes the game!

Dan Wallace

Been a big fan of the Element for a while now. Had the original Element and upgraded to the IV recently and I couldn’t be happier. I just love how clear the sound is and how streamlined the experience is. I also had an issue that was quickly a…

10/10 performance per price point with unmatched levels of customer support for my other purchases with JDS

Jacob Hostetler

I purchased the Atom Amp 2 to replace an aged Atom 1 that I cooked, and may I say, the housing construction switch from polymer to aluminum is a massive boon. The new volume rheostat and knob is very pleasant, however, I wish there was a toggle swit…

Jackson Burks

Excellent customer service, fast delivery. One of the best companies I have ever ordered from.

Adam Davenport-Hortle

Great products — works incredibly well with JDS Labs Core for EQ being incredibly intuitive. Engraving option fantastic customisation feature & engraving done really well. Shipping super fast :)

David Rot

As the title states I replaced an older Schiit Audio headphone amp with the JDS LABS Atom Amp 2. The purchase was based on an online review. It has a reasonable price point and works very well.

Jesse

Hey guys, I finally pulled the trigger on an element 3 and I’ve gotta say, I absolutely love it. The monolithic knob is exactly what I wanted sitting on my desk.

Trevor

Just want to say I am SUPER happy with my new Atom DAC 2 and Atom Amp 2. I’ve never owned a DAC or a headphone amp before. Totally blown away at the sound quality coming out of my speakers and headphones. Also great results pre-amping my Marantz…

Merrel Pepper

Purchased this and 2 other similarly priced phone preamps. The JDS Labs is DEAD quiet!!! Overall better sound then the other two and more features. The treble and bass knobs are a huge bonus. I don’t get into the little details of the sound like…

@iamkdh92

O2+ODAC soldered up and sounding fantastic. Was curious how well the enclosure engraving would turn out with the gradient… @jdslabs freakin’ killed it! Looks and sounds clean as hell!

John Hospod

I love the tactile feel of the volume knob. Really intuitive DSP interface and ever so slightly warm, yet super spacious and detailed sound on my Ayra Stealth. Amazing driving power. Never even need the high gain. Not as clinical as the Topping offe…

i have been searching for a small desktop headamp/dac for quite some time. My desk has limited space so can’t fit any big headamps. Found element iii mk2 online and it is just nice for me. The dac amp is so well built, elegant and powerful. I …

Hugo Sanchez

I don’t understand how in this small box can exists such performance. The pairing with the Caldera is perfect, enough for when I want to switch from music with my tubes to gaming with a light AMP/DAC that fits in my desk.

Dean Johnson

This is my fourth DAC from JDS, and every one has been perfect. I now primarily use them instead of any sound cards in desktop and notebook computers. Computer > USB, them receiver or O2 headphone amp. The Atom DAC 2 works using a Windows 10 base…

This thing is incredible!!

Loki C.

I love so much your Objective2!! A masterpiece!

Nick McKay

I was somewhat disappointed in my DT1770 Pro headphones until hooking them up to the Atom 2 Stack. I’m hearing sounds and instruments I’ve never noticed before in songs I’ve listened to hundreds of times. Exceeds my expectations te…

This is the missing piece to eliminate all noise from USB digital sources. My source is an M4 Max MacBook Pro into the Atom DAC 2. Sometimes I need to connect a PD-powered USB C hub to my machine since the MacBook only has 3 USB C ports. When you us…

Chuck Champion

Very handy device to reduce USB noise. I use my primary office PC for all work, gaming and playing my music library. Occasionally I notice some microphonic noise in my headphones when different components are being used. I added the Synapse in the U…

The Element III MK2 is such a well designed and executed DAC/AMP combo. The look, feel and function surpassed all of my expectations. Power is abundant and sound processing is clean and accurate. This thing powers my HD650’s to ear shattering le…

David M

Great sounding, no frills amp with plenty of power on tap that has easily pushes my current phones. This amp has me looking for new headphones to really put it to the test!

Bolt V.

My Objective 2 works great, and looks good to. Dropped some coin on a nice little Topping rack for it on Amazon. Thanks so much again JDS! I’m getting a lot of compliments on the sound and look of the amp

Johnny Maelstrom

Getting silence instead of noise from your headphones is amazing. This works and is worth the money.

Jock Stucki

I have never heard such quite sound form my turn table. No hum at all. Quality amp at an amazing low price.

Rick Pietruszka

Upgraded from an original El Amp to an El Amp II+. Very good (audible) improvement! No hype or other kind of smoke and mirrors, just good sounding music.

Steve Pierce

After a lot of research, I decided to purchase the Atom 2 DAC/AMP bundle from JDS Labs. I’m very impressed with the build quality and the clean, crisp sound I get from my recently acquired Beyerdynamic DT770 Pro X LE headphones is amazing. The q…

Kudos to @jdslabs — not only are their products breathtakingly good. Their customer service and support is equally awesome. Thanks for all the help 🙏

Darryl Melendez

This little thing is amazing. I was having a lot of issues with noise coming through my Marantz M1 from my DAC/PC. I saw the Synapse and decided to try it out because nothing else had worked for me. I’m happy to say that it is doing the job. I…

The JDS Atom Amp 2 is a power beast for the price, brings out the best of the HD6XX dynamic drivers, transparent, clean and powerful.

Gray Van Vliet

Dennis Glenn

There’s really no reason to review these guys make amazing stuff, can’t wait for the Atom Amp 3, assuming they’ll make it. Also the 3.5mm input on the back makes all my dongles sound amazing, tell everyone. Best endorsement is that all t…

Rafael GC

I bought it because I need to run long cables (aprox 15m) from my source (a laptop) to my preamp. It does the job, the sound is transparent and the build quality and design are great.

Jacobe Vanier

Bought it for my ATH-70XA cans. Works great and I like the online EQ. The dial/knob is very satisfying.

Dunring

Just got one of these the other day, have two of the original stacks but it’s the first + version. Wow, on the Beyerdynamic T90 they sound exceptional, just tons of power in low gain for 250 ohm stuff. 

John Hospod

Really impressive product and cool tactile feel of the dial. Sounds super clean and powerful with a hint of warmth. Amazing customer service too!

The DAC is simply superb. I use it connected to my Atom Amp 2 powering Beyerdynamic DT770 Prox Ex LE and the sound is crystal clear with a big sound stage. The customer service and fast delivery from JDS is exemplary. Highly recommended.

Collin DeRosa

Absolutely love this stack addition to my setup. Works perfectly with my desktop speakers and iems.

@JTCPingas

Huge shout-out to @jdslabs for early shipping on the Atom amp! I’m already in love with this thing! Thanks so much guys!

I didn’t really know I needed one of these. I bought it on a whim to try and holy moly it quietened everything that I didn’t know I was hearing.

Fixed The Lack of Galvanic Isolation from Mojo 2

Mannie

Holy explative, what a noticeable difference! My little PSBs were capable of so much more, and your DAC just brought it out. I think your tag line should be «you don’t have to be an audiophile to hear the difference a great DAC makes».

Nick Paul

This is an A+ class product from JDS. It performs remarkably well, unseating my previous stack in sonic performance. On top of that the EQ is superior to EqualierAPO/PeaceGUI’s performance and the fit and finish leaves nothing to be desired. Def…

Alright, so I wasn’t really a headphone person before this. Like, at all. But I figured, hey, maybe a dedicated amp would make a difference? So I grabbed the JDS Labs Atom Amp 2 as my first one. Seriously, best decision. I already had the X-Duoo…

I have used the atom AMP 2 and DAC 2 with my Meze 109 Pro for a couple months and must say I absolutely love it, really brings out the detail in music, and all in all is a great fit since the sound on the 109 is balanced, but a bit on the warmer sid…

Love the element 4 and the buying experience and support is second to none. Good honest business people who look after their customers

Matthew Mumpower

I’ve never had a DAC, closest I ever got were dedicated sound cards back in the day. This Element is treat for the ears. I’ve got 1,000’s of hours in some games, and with this its like experiencing sound for the first time again. Games s…

I don’t believe in altering the sound signature of iems or headphones, the JDS Atom Dac 2 perfectly reflects this, sounds transparent and uncoloured.

I bought a Hifiman edition XS to use with mye 2024 MacBook Air. The sound was ok, but not impressive. The JDS stack made a huge difference to the sound! Lots of space, deep bass and magnificent vocals.

Dalton Rooney

The improvement in clarity on the low end was immediately noticeable compared to my previous DAC. I took advantage of the free engraving and the result came out great. Well worth the money.

This is my second JDS Labs product, starting with the first Atom AMP and i’m still blown away by how good the support and the products are. The long wait for the Element IV was completely worth it. I was completely shocked on how good it perfo…

The XMOS USB Audio firmware supports both USB Audio Class 1.0 and USB Audio Class 2.0.
Most modern operating systems now support this functionality natively, in some use cases an additional drivers may be required.

Third Party Windows Drivers

For some applications it may be desirable to use a third-party driver for Windows. A number
reasons exist as to why this may be desirable:

  • In order to support UAC 2.0 on Windows versions earlier than 10
  • The built-in Windows support is typically designed for consumer audio devices, not for professional audio devices
  • The built in drivers support sound APIs such as WASAPI, DirectSound, MME, but not ASIO.

For advanced feature support in professional applications using Windows we recommend the USB Audio Class 2.0 Driver from Thesycon, which includes the following features:

  • Available for Windows 10 and Windows 11 operating systems
  • USB Audio Class 1.0 and 2.0 asynchronous operation
  • Designed for professional audio devices and consumer-style devices
  • Supports ASIO for transparent and low-latency audio streaming
  • Supports Windows sound APIs such as WSAPI, DirectSound, MME
  • Supports high-end audio features such as bit-perfect PCM up to 768 kHz sampling rate, native DSD format (through ASIO) up to DSD1024
  • Multiple clock sources supported, such as SPDIF or WCLK inputs
  • MIDI 1.0 class, including MIDI port sharing
  • DFU (Device Firmware Upgrade), including a GUI utility for firmware update
  • Control panel application for driver status/control
  • Additional advanced and custom features including signing, branding etc available on request from Thesycon

Thesycon provides a free evaluation driver which can be used with the XMOS audio development kits.  This driver includes all the features above, but is restricted to use with XMOS devices and after 60 minutes use introduces a beep tone every 5 mins into the output.

Hi Folks,

I have a Questyle CMA-400i and there is a driver error in Windows 10. There is a device called XMOS DFU (device firmware update I believe) and I can’t seem to find a driver to resolve the error. The DAC appears to work okay with Windows 10 and JRIVER which I am using to send music files to it.

Has anyone had any experience resolving this issue and, if so, how were you able to resolve it? Any help would be greatly appreciated!

Cockpit error on my part. For some reason the system was operating with the Windows CORE driver set. I ran the installation .exe twice and finally got the correct drivers to install and the XMOS DFU driver issue has been resolved.

sw_usb_audio: USB Audio reference designs

vendor: XMOS
version: 9.0.0
scope: General Use
description: USB Audio reference designs
category: Audio
keywords: USB Audio, DFU, USB, I2S, ADAT, SPDIF, TDM
hardware: XK-AUDIO-216-MC, XK-AUDIO-316-MC, XK-EVK-XU316

Summary

The XMOS USB Audio solution provides USB Audio Class compliant devices over USB 2.0 (high-speed
or full-speed). Based on the XMOS xcore-200 (XS2) and xcore.ai (XS3) architectures, it supports USB
Audio Class 2.0 and USB Audio Class 1.0, asynchronous mode (synchronous as an option) and sample
rates up to 384kHz.

The complete source code, together with the free XMOS XTC development tools and xCORE
multi-core micro-controller devices, allow the developer to select the exact mix of interfaces
and processing required.

The XMOS USB Audio solution is deployed as a framework (see lib_xua)
with reference design applications extending and customising this framework.
These reference designs have particular qualified feature sets and an accompanying reference
hardware platform.

Please note, Alpha and Beta releases may not accurately reflect the final release and documentation
may not be complete.
These early releases are not suitable for a production context, and are provided for evaluation
purposes only. See ‘Release Quality & QA’.

Refere to CHANGELOG.rst for detailed change listing.

For full software documentation please see the USB Audio User Guide document.

This release is built and tested using version 15.3.0 of the XMOS tool set.
Build or functionality issues could be experienced with any other version.

This repository contains applications (or instances) of the XMOS USB Audio Reference Design framework.
These applications typically relate to a specific hardware platform.
This repository contains the following:

app_usb_aud_xk_evk_xu316 xk-evk-xu316 xcore.ai Evaluation Kit

Please refer to individual README files in these apps for more detailed information.

Each application contains a «core» folder, this folder contains items that are required to use and
run the USB Audio application framework.
Mandatory files per application include:

  • An XN file describing the board including required port defines.
  • xua_conf.h header file containing configuration items such as channel count, strings etc.

Each application also contains an «extensions» folder which includes board specific extensions such
as CODEC configuration etc.

Additionally some options are contained in application CMakeLists.txt files for building multiple
configurations of an application.
For example an application may provide configurations with and without MIDI enabled.

Known issues

General known issues with this release are listed below.
For board/application specific known issues please see README in relevant app directory

  • (#54) When DFU flash access fails the xcore sends NAKs to the USB host forever, rather than a STALL
  • (#97) Documentation missing for XK-EVK-316
  • (#99) Input via TDM master unreliable due to low-level timing issues (xcore-200 only)
  • (#120) Playback glitches experienced at 44.1/48kHz when using ASIO4ALL (v2.15) with built-in windows drivers. USB bus traces prove that these originate from the host driver.
  • (#14762) When in DSD mode with S/PDIF output enabled, DSD samples are transmitted over S/PDIF if the DSD and S/PDIF channels are shared, this may or may not be desired
  • (#14173) I2S input is completely disabled when DSD output is active — any input stream to the host will contain 0 samples
  • (#14780) Operating the design at a sample rate of less than or equal to the SOF rate (i.e. 8kHz at HS, 1kHz at FS) may expose a corner case relating to 0 length packet handling in both the driver and device and should be considered unsupported at this time.
  • (#14883) Before DoP mode is detected a small number of DSD samples will be played out as PCM via I2S
  • (#14887) Volume control settings currently affect samples in both DSD and PCM modes. This results in invalid DSD output if volume control not set to 0
  • Windows XP volume control very sensitive. The Audio 1.0 driver built into Windows XP (usbaudio.sys) does not properly support master volume AND channel volume controls, leading to a very sensitive control. Descriptors can be easily modified to disable master volume control if required (one byte — bmaControls(0) in Feature Unit descriptors)
  • 88.2kHz and 176.4kHz sample frequencies are not exposed in Windows control panels. These are known OS restrictions in Windows 7 and earlier.
  • Compatibility issues exist with the Microsoft built in UAC1.0 driver (usbaudio.sys) and Intel Smart Sound Technology (SST) can result in audible distortions. This can be worked around by disabling the SST driver.
