^^ You guys are hilarious. and have good taste.

Just wanted to share something I'm presently messing around with- high quality but inexpensive usb to aes / i2s digital sound card. build quality seems top notch and the components in it are well worth the under $200 price. note that for i2s it uses the hdmi format connector, not ethernet type, but that could be adapted if necessary.

You can get it directly from amazon too, which is safer and faster for us USA folks.

i just got it and am letting it break in before testing. i have it hooked up to a freshly built Intel-based mini fanless pc, quad core, ssd drive. I will run ASIO sound drivers and put Roon on it. My music files are stored on a large QNAP NAS. Anyway it was hard to pass up for the measly price and if it is less than I'm expecting, amazon has a good return policy...

Note this is not a DAC, it is strictly a USB input to digital output type of device. I have no interest in purchasing an outboard DAC when I'll be getting D3 cards in the near future. I have D2 right now.

I decided to front end the Gustard U12 with a new small fanless pc. picked up this one from amazon and it is a real good deal. I usually build my own from a barebones case but this one was such a good configuration and form factor for the price, couldn't pass it up. It works work great right out of the box, easy setup- it even comes with an RF remote. And, it dual boots to android 5.1 or windows 10- All pre configured. Very well done. And the foot print is smaller than a CD case.

So I have the Gustard connected, ASIO drivers and USB Audio 2.0 drivers set up, and using hifi bridge software to bypass the internal windows directsound and go from source (tidal, foobar etc) direct to the Gustard XMOS USB Audio 2.0 driver. the unit is outputting 24/384 from AES, but of course I am going to have to reduce this to 192 for inpu to the Theta CB's AES.

I did some very basic quick listening, and even at 44.1, the Gustard U12 is very black, open and silent. Wide stage. It's a freaking ridiculous bargain of an audiophile device for less than $200. The case, display, fit and finish are top notch. The pcb is done with pride. The linear power supply is well done. I would probably upgrade the caps with something better quality but that's about it.

Tomorrow will install Roon and get the rest of things set up.
