The X20 is good, really good. For the price it is hard to beat!
Your previous post said up to 256 via USB, not 128.
I am getting 128 with no problems via USB. I am interested in 256 or 512, which, according to Gustard, needs I2s input.
Be careful - the Gustard outputs 4.6V on the XLR
This is excessive and will distort most preamps which typically require < 1v.
could you please elaborate a bit on this? since my x-20 is linked via XLR (to cd transport and also to pre-amp) I find this statement a little worrisome.......
Check the input voltage sensitivity of the preamp and then adjust the volume on the X20 in -3db increments to halve the output. For example, if the preamp input sensitivity is 1v, then -6db would reduce the X20 output to 1.15v. Therefore select -7db or even -8db so as not to overload the preamp.
What's the rest of your system? I had the gustard x10 and the upgrade to the x20u has been well justified. I don't know if the improvement will be the same for the x12. Gustard spent 2 years (?) Building the x20. I don't think Gustard would offer the x20 as a x12 replacement unless the improvement was noticeable. I have found the x20 to be much more sensitive to the quality of the music source (16 bit vs 24 bit) with 24 bit being noticeably more refined. I upsample all music in foobar to dsd128. Based on other comments in this thread you may be better off with a regen -- comes back to the quality of your PC USB port?
I think you are probably right about the improvement, but I guess I need to be reassured. I am getting the best performance out of my system I have ever heard with the Gustards. I am a snow-bird so I have two systems, I don't use headphones. If the x20 is good enough, I might carry it back and forth.

What is a regen?
I own a Gustard U-12 and x-12 and largely due to this thread am considering the x-20. I have been very happy with the x-12 and in fact it has been the best dac I have heard, better than the more expensive Audio-GD NFB7, Nuforce dac-10, and others. First, I would like to know if I need to get the U version with the usb built in. Some earlier comments said that it sounded better with the usb card than with the U-12. This seemed to be surprising since I read the opposite regarding the x12.
Second, I would like to know how many here think the improvement is well beyond subtle. I appreciate sturatmc's opinion and how diligent and articulate he has been on the subject, but I feel better about making a purchase when there is a broad consensus. I have had the experience of reading about a Tripath amp a few years ago that one enthusiast endorsed brilliantly, but the quality was not there when I bought.it. Also this hobby is so subjective, equipment variables, tastes, etc.I have had the experience of finding the U-12 has upgraded the sound of the built in elderly dac, limited to 48kz, on an old (more than 10 years) Mcintosh MSD4 surround decoder preamp/processor. It easily was as good as the Audio-gd NFB7. So the interesting question is have we really come that far in terms of dacs or just clocking and jitter removal. Anyway, more opinions would help me decide if the step up to the x20 is a baby step or a giant step. Thanks to all who respond.
Also, I suggest you give Foobar a go - a lot more complex than JRiver but more options and more fun - you need a good PC or Notebook with i5 or higher (Jriver benchmark 2000 or higher - see the JRiver help drop down menu for the benchmark). See my earlier post for the foobar plugins. Also suggest in Foobar you upsample to 192k (using Sox) and then to DSD128 for output to the gustard. Foobar focuses on sound whereas JRIver places a lot of emphasis on video as well. You also have to buy the annual upgrade. And use a wireless tablet to drive the PC / notebook - a lot more convenient.

It also makes you want to expand the music collection. I see you have a lot of SACDs. Ripping these to DSD (or DSF) files (you need a 60GB PS3 to do this) will really bring out the strengths of the Gustard.
