Jafant,
My system:
PS Audio P10 Power Plan
PS Audio DirectStream DAC
Autonomic MMS-5A Music Server (with all hi res AIFF files)
McIntosh C50 Preamp
McIntosh MC452 Power Amp
Wireworld Cabling
JL Audio F113V2 Sub Woofers (2)
Focal Sopra No2 Speakers
Sennheiser HD800 Headphones
I would say these Focal's may not be the ideal speaker for everyone. I suspect they might sound too harsh, with electronics that might bring out too much from those fantastic tweeters.
I found them to be the most sensitive and "accurate" in the mids and highs of any speaker I auditioned which I'd characterize as being of a "musical" design.
Really enjoying my new components!
