The best USB available is not FTA nor any model else, the very best is PRANAWIRE ARHAT USB ultimate. Only available at PHP AUDIO. This is a stellar project I ask to Joe Cohen to design and build the very best USB cable for my TAIKO AUDIO or WADAX customers. Stay tuned for prices, pictures and ... listening results !
I will open a dedicated subject about USB cables because it's more interesting than I thought a year ago. I think a lot of USB cables sound different but rarely really better. Also nothing could justify the way you answered. I have complete right to say what I hear and it was not a business approach but more an advise as this Californian designer and manufacturer is well know for his power cable, interconnects ans speaker cable than for his USB cable (even if Photon LS is very good). I seen that you live not far from me and we share the passion for ribbon speakers, may be we can meet one day.

Please don’t say “all amps sound the same” but rather, “all the amps I have heard sound the same to me.” Following this rule not only makes for a calmer atmosphere, but also saves you hours and days of aggravation while you try to defend your point of view!
Did you get the chance yet to audition the Themisto? I am curious if it retains sny of the Callisto's sonics, especially as i may move off a usb dac and have not found other spdif that will get close to the fta usb.
