I know the U18 uses the 'problematic' TE8802L chip, but have the drivers been sorted out yet? I know the company provides drivers. The Matrix would not require any drivers, as I'm on OSX. I want the ability to play 24/192 files, that is why I am looking at these. I would be going into my Denon AVC-A1SE. I also have a Xindak Dac5, which is connected to my PC via a Emu 1210m. This card does 24/192, but I could also use the USB-SPDIF device with this DAC too and see if the results are any better.
BTW, the Xindak is an up sampling DAC (96 or 192 selectable). If I give it a 192Khz sample rate to start with, and chose 192Khz for the output, will it pass it through, or will it resample it, resulting in possibly lower jitter?
Both of these converters are similar prices, so it's all about performance. Anyone know which results in the lowest jitter signal?
