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.

Youre purchasing / bidding on theitem in the title! Over the next month or two, Ill belisting some nice quality watches, high end headphones and amplifiers. This isnot part of my regular listings since I post 90% sports cards and memorabilia undermy account. The watches and audio equipment collectionare from a MILITARY VETERAN AND CURRENTLY A PRIEST who I consider a friend. His collection was mostly purchased while he spent his time serving our country overseas. As a priest, he does not have the disposable income or time to be ableto post these items for sale nor does he have the space to store his collectionin his humble living area. This person is very meticulous and A type so many of his items were kept in original boxes. Please review any and all pictures forthe quality and condition of each item, but if you need more information orpictures; please request through the eBay messaging portal. Also if youre interested in purchasing more than one item, I can combine S&H to try save some money; everything will be based upon weight and designation. Good luck and thanks in advance!!! Disclaimer for AMPS: If unit requires tubes, I dont know how long the tubes have been in storage or last used. Every amp being sold should have tubes included and will be packed with extra care. Please be aware that you may have to replace one or all tubes. Some info that I found on this unit: strong power supply that uses two 50-watt O-type transformers, the unit features a variety of inputs and outputs, well suited for powering any type of audio rig. Outputs include a fully balanced XLR out and RCA, while inputs include HDMI, optical, coaxial, BNC, and AES/EBU. If you already have a USB interface, you can pick up the version of the DAC-X20 without USB. Otherwise, opt for the USB-equipped version with an XMOS 32-bit USB receiver chip. LASTLY: This item can be shipped in its original box since thats how my friend originally received it. Please advise me prior to shipping if you would like your purchase to be boxed within a box method which will more than likely change the cost of S&H.
