@herman, thanks for sharing your experiences. Yes I agree the jitter control and upsampling benefits can be solved in high end DACs instead of using these sorts of boxes. But, money. I need more of it to get a DAC of that caliber, premium power cord, and premium interconnect. Ideally I’d have an Innuos Statement and a Chord Dave or something. But again, money…The PhoenixUSB box defining helps me get my digital chain a lot of the way there with a lesser streamer and a lesser DAC.
Also, I’ve not mentioned this. Terry’s Gryphon Diablo 300 review (Pursuit of Perfect System) mentioned that the Diablo DAC module has a weighty, energetic, “live” quality to it. But also noted it could not keep up with Chord TT2 + M Scaler with detail clarity and focus. He noted that the TT2 and M Scaler lost this “live” scale factor. While the Diablo DAC module is a lesser DAC vs pricier standalone DACs, I like its character, which is synergistically matched with the Diablo 300 amp, just as Terry also noted. So in this respect, there value in being able to keep this character of the DAC while compensating for some of its shortcomings with the PhoenixUSB. The M Scaler however creates more jitter again though, as confirmed by Rob Watt, and to me that seems like it would undo what my PhoenixUSB does, which is remove jitter.
