I should probably disqualify myself from giving any SQ impressions given that I am using an unfamiliar DAC (CA DacMagic 100) while my usual modded CA840C is out for repairs, but here are some anyway. Obviously I can't tell whether these are artefacts of the DAC or the playout via SBT. The CA DacMagic 100 plays perfectly without a hub in USB2 mode, but I couldn't get USB1 to work properly at all with the hub I had lying around.
1) 24/192 playback via Async USB2 and SP/DIF works with the samples that I've downloaded from 2L. I haven't noticed any glitches, clicks or other problems. 2) Standard Red Book audio, 16/48, 24/48 and 24/88.2 files also play without glitches via Async USB2 and SP/DIF 3) via both USB and SP/DIF, Bass sounds somewhat lightweight and 'hollow', lacking resonance but with good texture and pitch perception. To my ears, Bass has slightly more weight via SP/DIF, but not a big difference 4) via both USB and SP/DIF, Mid and upper mid sound detailed and well differentiated. Snare patterns are easy to differentiate, and vocals and quiet production effects are easy to hear. There appears to be a lack of etch and grain, and recordings with a warm acoustic have a nicely burnished quality. 5) Clear treble and patterns/accents in high-hat or other cymbals seem quite easy to hear. No harshness via either USB or SPDIF. The presentation via both USB and SP/DIF is a little mid-forward, but not hard-sounding or grating. Smooth and natural sound piano sounds via USB, but slightly better impression of detail via SP/DIF. SQ of this combo in my system sounds slightly like it is equalised with a slight 'frown' curve. I am most impressed that it works as well as it does. The primary benefit is obviously providing compatibility with USB DACs, but the ability to playback 24/192 via SP/DIF is a bonus too if your DAC can manage it. SP/DIF is my marginal preference with this DAC in my system.
