Thanks for the thoughtful and well written review. I look forward to reading your thoughts on DSD playback.
I have the Audiophillio 1 with Pure Power and have always wondered whether the Off Ramp was better as some have claimed. The Off Ramp is 1k higher in price than the Audiophillio with Pure Power and I am quite pleased with the improvement that the AP1 w/PP brought to my Anedio D2 DAC. It seemed unlikely that $1k would be worth the switch to the Off Ramp. I am glad now that I didn't switch.
That being said, I am going to sell the Anedio D2 to purchase a DSD capable DAC, such as the Resonessence Invicta Mirus or the Benchmark DAC2. I love the sound of DSD!
Phillip, the Audiophillio designer states that the model 1 and 2 will pass DSD when it is DOP - DSD over PCM. I don't really know what that means exactly, as my Anedio doesn't playback DSD. If I download a DSF file, will that playback on the Chord/Benchmark/Resonessence through the Audiophillio? Anyone know?
