I’ve played my Gustard Dac with my old Sony CD player. The Gustard Dac added clarity & subtle refinement, still allowing the soft, slightly warmer sound of the Sony to come through. This Gustard was purchased about 6 years ago for $1200 and used for about 3 years. After that, it has been in a box in heated storage. It’s in excellent condition and I highly recommend it this Dac for any CD player. *comes with remote & plug in cable

Original price was $1400 now you can get it for small fration of the cost.if you pay close attention to the build, you will notice it uses the same linear power supply and configuration of the much more expensive models going at 1500 and $3000 components inside matters. That’s why I took the cover off for all to see this beautiful piece of equipment.Will smoke anything under $1000 especially some of that cheap Amazon ch-fi sound DACs That seems to be the trend people are getting the latest chipsets but there’s no linear power supply like this quality item.They is absolutely no refunds on this however, it works 100% and tested . Ships within three days after purchase partially handicap. Also my silver cones are for illustrating purposes only Not for sale .

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.

The DAC ConverterGustard X20 XMOS double ES9018 SABERis designed according to the rules of the art. This DAC 32bit 384Khz has a USB 2.0 class of very high level. With an accuracy of 0.1PPM and a power of 500MIPS with processor CPLD Altera MAX II,the DAC X20 offers a high resolution, a very low jitter, an output entirely in discrete symmetrical transistors in class A.The quality of its components (clock ESS ES9018 TCXO 100MHZ), its processorAltera MAX IICPLDwith 8MB of built-in memory predestines its use on high-end Hi-Fi systems. Of course, this DAC with its asynchronous USB inputs with three separate clocks decodes the DSD 64, 128, DXD 32bit 384Khz being fully ASIO bit perfect under Windows (requires a driver supplied on mini CD).An advanced clock system:The DAC Gustard X20 offers a classic asynchronous digital mode as well as a Automatic Adaptive Technology Master Clockautomatically deriving on the correct TCXO clock frequency under the best conditions (A clock dedicated by multiple frequency).An analog stage in discrete transistors with gain selection:The analog output stage of this DAC Gustard X20 in Class A offers three front selectable gain stages: 0dB, 6dB and 12dB. So with the volumedigital 64bit ESS without loss of dynamic, one can directly attack by the balanced XLR outputs where unbalanced RCA, a stereo power amplifier.A separate digital and analogue power supply:Its linear power supply with dual toroidal transformers (one for digital, one for analog) shielded provides a very low noise level preventing jitter by electrical pollution. The control section offers ROVER capacitors with high filtering capacity, LM2941 and discrete transistor based regulators.HDMI / I2S compatibility :The entry HDMI to I2S formatDAC Gustard X20 XMOS is compatible with Audio GD format. (See the diagram at the bottom of the description.)General technical characteristics:TCXO full size clock 100Mhz (ES9018) (0.1PPM).Altera MAX II CPLD processor.Real outputs in Symmetrical schema on XLR.Analog gain stage 0dB, 6dB, 12dB.Digital volume ESS SABER 64bit non-destructive in steps of 1dB.Selectable DSD filter 50, 60 or 70khz.Sharp PCM filter and Slow Roll OFF.Phase reversal 0 °, 180 ° by the display.Digital Inputs:One input USB Audio class 2.0 32bit 384Khz DSD 64 and 128 DOP128, DSD512.An I2S input on HDMI (see wiring diagram) 32bit 384 KHz and DSD 64, 128, 256, 512.A standard input IEC60958 AES EBU 110Ohm gold plated pins 24bit 192Khz (compatible with DOP64).a standard input IEC60958 BNC SPDIF 75 Ohm plated Gold insulation PTFE (compatible DOP64).A coaxial input to standard IEC60958 PTFE insulation 75Ohm Plated Gold 24bit 192Khz (compatible with DOP64).A Toslink optical input to the IEC60958 24bit 96Khz standard (DOP64 compatible).Analog Outputs:An analog balanced stereo output gold-plated pins.An analog stereo output on Cinch RCA CMC plated Gold PTFE insulation.The bundle contains:An IEC power cord of 1m75.A mini CD containing the XMOS drivers.
