Blue Circle BC3 Galatea - thoughts

Although I can't comment directly on the sound of the BC3, I can comment on the sound of the BC3000 (which uses the same GALATEA power supply) in my opinion this is one of the finest sounding (overall) pre-amps that I've had the pleasure of using. I've listened to the BC21, and although it's good, the BC3 and 3000 are in another realm altogether.
I'm running the 3000 with a pair of BC8 mono's and continue to be impressed with the sheer listenability of this combo.
Yup.. my handle is "Bigpoppakrell" .. but guess what? the Krell is GONE..and the music is BACK !
So.. to help with the original question of this string, I would suggest that if you do decide to go for a BC3 make sure you can get the Galatea power supply, it really does make a BIG difference to the pre amp.
As for mating with a Classe amp, it should work pretty well. If you really want to enjoy the pre-amp though, have a listen to the BC26 power amp (or better still the BC8's), it was the amp that made me realize that the Krell had to go...
Cheers !

"The BC3 is more transparent and revealing, but in my system, I prefered the smoother midrange and slight bloominess in the bass of the SEP1. Both pre's use the same 6922 tubes, yet sound distinctly different. The BC3
sounds solid-state-ish in comparison to the SEP1, which sounds a little creamier."

As we all know, sound presentation exists along a spectrum and depending where you are on it, anything to one side will sound cooler and more objective and anything on the other side will sound creamier, smoother, and even warmer. I own a BC 3 and bought it to replace a Krell KRC 3: the Krell was warmer (!) and more opaque. It also had less life, but that's another matter. To my ears, the BC 3 comes closer to being perfect than any other preamp I've heard under $6000. It competes favorably with the CAT, which is all the praise it needs. If your preamp is creamier and smoother than a BC 3, it's holding back the music. Dammit, there's ice cream down under that whipped cream!

I have to disagree with Bob. My pre does anything BUT hold back the music, it gives me a more pleasing "musical" sound as opposed to the clear, "hifi" hear every little tick and twang kinda sound. I'm not bagging on the bc3, I think it is an excellent preamp, just not for my tastes. I couldn't overtly point out any colorations with it...Monk demo'd 5 pre's and he didn't prefer the bc either, so go figure.
Sometimes too much of a good thing isn't good. Hearing every last detail didn't make my system better, just different. Demo it and see what you think. Good luck.
