Jsadurni, I like both units. I couldn't pick a real winner. Both units sounded about the same too me. The Bent was setup with 6dB extra gain. So it wasn't easy to get a volume match on both units. The Bent is the better built of the two..being all metal. Performance wise..dollar for dollar the nod goes to the Promitheus. At the price..it is unmatched at what it does.. and far beyond the price. I had communications with several owners and people that have tried one out. It may surprise some the preamps and CDPs direct that have been pitted against the little guy.
Modwright,SAS,Conrad Johnson 17LS, Copland, Loecsh/Weisner and Wright preamps,Audio Research,Wadia 860 and Levinson CDP straight into amplifiers. That's just a few of the ones I've come across...the list goes on!
If you didn't take my advice before Jsadurni and pick one up earlier. The waiting list is so long now..it's almost insane!.. 2 to 3 months at least.
I ordered two more, one for me and the other for a friend..it slaughtered his Eastern Electric MiniMax..you'll see I've sold it on Agon recently...these two are the Reference versions with fully balanced trannies,solid silver RCAs, metal top/bottom plates and a few other additions to my basic version.
