The best passive preamp

Thank you very much!

Have any of you Bent users heard the Sonic Euphoria PLC? I'm curious about this unit because the Bent is no longer available, and because they have a 30-day trial period.

Also, roughly what conditions would contraindicate a passive?

I had the Sonic Euphoria and liked it a lot ... butthe First Sound Passive Preamp (Reference II) was a tad better resolving complicated passages.

Hope this helps

Thanks. Apparently the output transformers in my modfied CDP would not be a good fit with the Sonic Euphoria, which has an input impedance listed as 500-1000 ohms. Perhaps all passives need to be ruled out.

I would like to know what amps and CD/source components you who say the NOH was so good were using? My experiences with passive preamps (McCormmack TLC,Pass Aleph L/P, and others) has been dissapointing from a dynamics stand point...at least with the combo's I've ever been associated with.
I'd conceed that maybe there's some impedence matching issues, but not sure.
Any recommendations? I've tried passives with everthing from a few Tube amps, to Classe's, to Threholds and Pass Labs, to Coda's, McCormmacks, Meridian's, and more. I've yet to get dynamics like I do from a good active 2 channel pre in my tries over the years. And, for the same token, I've never heard dynamic results (although clear and detailed) from others passive combo's. Maybe someone could steer me to some source/amp combos to try.
Sure....I'd try the passive route again if I knew I could get my dynamics I so crave.
