Dan...Thanks for the kind words, I appreciate it very much.
Avnut...You are correct, you don't need a ton of power with the B&W Nautilus series, but they really do sing with higher current amps. My "nuclear power station" comment may have come across that way, sorry about that. And as you stated, careful attention to upstream components (with ANY B&W speaker) is critical to get the best sound.
The Khorus (and the entire Talon line) are definitely more forgiving AND musical than the B&W line, IMHO. This is not egg on the face of either speaker, just a difference in the way they present the music.
The best set-up I have heard running the Khorus? Wow, that is a tough question...Mainly because I have heard them with so many different systems and they all had their pros and cons. If I had to pick just one it would be:
Acoustic Zen cables
Electrocompaniet EMC-1 MK2 CD Player
Edge M-8 Amplifier
Simaudio P-5 Preamp
Off the top of my head, other amps/preamps that I have been VERY impressed with running the Talon products are the latest Electrocompaniet, Rogue, Pass Labs, Simaudio, Jeff Rowland, Power Modules, and First Sound (I am sure there are others, just can't remember them right now).
Lately, we have been running the Khorus X in the showroom with a Power Modules (Belles) 350A and the Shanling CD-T100 direct into the amp with VERY good results.
Hope this helps.
