I have one hell of a collection of audio gear so take advantage before its all gone. I found the mod details online. You can read it here: http://tweakaudio.com/EVS-2/Gustard_X20_Mods.html >>>>>>>THIS MOD HAS BEEN DONE ON THIS DAC!!!!! <<<<<< THIS GUSTARD PRO DAC HAS HAD THE COSTLY EVS MODIFICATION DONE TO IT TO INCREASE THE MUSICALITY OF THE ALREADY GOOD DAC. 1. Bypass the fuse with copper foil (or use audiophile fuse if this scares you)....now I even bypass the fuse holder for even better sound.2. Remove the hardware from the transformers and raise them off the chassis using doubled up carboard donuts. You can then use nylon nuts and bolts without much tension to hold them in place.3. Twist all AC wires tightly (both into and out of both tranformers and between front and back boards). You have to remove the heatshrink tubing from the wire before you can twist them.4. Remove the input AC filter.5. Remove the 110/220 volt selector switch. (USA USE ONLY)6. Remove 5 AC connectors inside the unit. You have to desolder and remove the circuit board mounted to the AC inlet.7. Remove the power switch.1. All 7 AC power mods listed above.....incredible!....incredible.....incredible!!!! Included is a complete byass of fuse holder and fuse.......audiophile fuse extra.2. WA Quantum Chips on power supply caps.....noticeably more detailed and transparent.3. Damping of loose mounted caps, many electrolyics,clock, etc...... more focused and clear and real.4. Changing rectifying diodes on output board to damped soft recovery types......OMG, so much more 3D and inner detail5. Remove the digital cable between the board and install low jitter Crystek clock right at the DAC with modified Wima bypass cap with WA Quantum chip installed.This mod has no power switch.....you plug it in...it is on. No need to turn it off...uses little electricity. The switch will degrade the sound slightly. BECAUSEOF THIS, THE LEFT KNOB IS PURELY ORNAMENTAL.

This DAC is fully functional and sounds great ! (Amazon new: $1,649)Please search YouTube to see lots of good reviews. Dual architecture: Independent R2R 1Bit,support native PCM native DSD and DSD to PCM.PCM NOS: Without any digital signal processing,bypassing the volume adjustment,raw PCM stream was decoded by the R2R array directly.Native 1Bit DAC,support DSD 512 (via USB)and DSD 1024 (via IIS).The DSD stream decoded by the independent 1 bit convertor without DSD to PCM converting. *Volume is fixed under this mode.Streamer/Renderer: Support roon,upnp and more protocols in the future.Replace the input signals clock with precision oscillators (local or external). Interference from the input sources clock is avoided.

You are bidding on a Gustard R26 R2R Digital to Analog Convertor(DAC). Works great, in excellent condition, I am simply moving and I dont want to take two DACs with me. My other DAC fits better with my current setup so this one is going. I have included a link to the DAC below so that you can get more of the details, although I would assume that if you are looking at this DAC you already have a good idea what you are getting since it is a fairly expensive DAC.

The device comes in a sleek black color and is perfect for use in any home audio setup.

It is perfect for feeding your higher-end DACs in particular that have I2S input (I was feeding my Musician Draco with this DDC via I2S, and it sounded better than any other input option on my Draco), and also for cleaning up the signal from your USB-equipped source. The unit has been broken-in for you with about 800 hours of listening time, all spent outputting in I2S. Included is a grounded/3-prong US-style IEC power cable. I did not include a USB cable since most people buying a DDC will have their own, higher-end cable ready (this unit’s input is USB-B). I never received any sort of manual with this unit, so I didn’t have one to include. It is, however, available online in digital format here: https://manuals.plus/musician/draco-r2r-dac-hifi-entry-level-decoder-manual
