Do you suppose this means the DAC19DSP is getting upgraded to the DSP-3? As the DSP-3 is used in the A-GD USBface. Anyone know the differences from the DSP-1? I just noticed the USBface announcement on the A-GD front page is gone.
I've always fed the DAC19DSP with an Empirical Audio Off Ramp 3 into SPDIF. I'm taking most of my system to friend's house this weekend. He has my newly acquired Magnepan MG12 connected to his tube gear. Gonna be trying a number of things this weekend using the C-2 and DAC19DSP combo. We'll try the normal USB input and add a DIYParadise Ultravox (ADUM4160 galvanic isolation on the USB) versus the Off Ramp. The Magnepan's excellent imaging will be very revealing of added jitter in the system, anticipating it will reveal the strength or weakness of DAC19DSP's USB input.
I've been using Burson opamps in the C-2 for a couple of weeks. They sound magnificent. Richer timbre compared to ACSS, more dynamic, more colorful across the range, very well balanced, warm, and absolutely no fatigue. Also adding a Wyred4Sound ST-500 ICEpower amp, arriving in a couple of days. I know you guys love your cans but I maintain the C-2 is a great preamp (beside a great HP amp) with the benefit of being the only Audio-GD product that allows the use of opamps to tailor the sound.
