@danmar123 i have a Stream1 with the separate USB Phoenix reclocker in my dining room system (also with an LTA Aero, and a Coda CSib v2 integrated with JA Perspective Graphene speakers). The Aero is happy with the USB feed in that set up. LTA does say that the Aero is designed to excel with either USB or SPIDF, and to my ears, that has been essentially true. I use an LTA LPS+ for the Stream1. That seemed to help a bit; not a night & day difference. My USB on that is Veritas Audax from Phoenix to Aero and DH Labs Mirage from Stream1 to Phoenix. Not surprisingly, that performs better (especially in terms of PRAT) than the stock Innuos cable and a TODN.
@fthompson251 when i had the N200, i tried both USB and coax/spidf. I preferred SPIDF slightly. With the N20, i have not tried USB, but if you believe Aurender (and various commenters), you would not expect USB to be better. I’ll say, though, beyond the better clock, the N20 has the better power supply and overall construction, and that does improve soundstage and noise floor. Presumably, those benefits would still be present via USB. In any event the improvement is noticeable, but by no means major. The N200 is a reality fine streamer and very synergistic with the Aero. (Finding tubes whose sound I liked was a bigger improvement than the move from N200 to N20, but the combined effect of the two is really, really nice.)
