Matching preamp to amp

This is exactly what I have been trying to figure out, impedance matching. I am probably going to go with a pre and an amp from the same manufacturer, Blue Circle. The BC22 amp has an input sensitivity of 22kOhms, whereas the BC21.1 preamp is said to have an output impedance of 180 ohms, which translates into a 122:1 amp:preamp ratio.

Does this make sense to you? I'm not very technically knowledgeable, so please forgive my ignorance.

Thanks.

Hi Gunbei,

Thanks for your response. I got the BC22 spec from Gilbert and the BC21.1 spec from the review on Soundstage. I had been thinking about a different pre that requires an amp with 50kOhms to operate ideally. I've decided to go with the BC21.1. :-) Can't wait to get it, but it won't arrive until later this year. :-( The midrange is where the magic resides.

Question: what should I do for a pre while waiting for the 21.1? I'm thinking maybe my old Denon receiver or the Channel Islands Audio passive VPC-1 (only US$250) to tide me over for now.

Gunbei,

Thanks very much for the advice/info re: Luminous Audio AXIOM. I will check it out and maybe give Tim a call.

I did indeed decide to go for the Shallco on the BC21.1. Everything I've read/been told recommends it. Gilbert and BC have been excellent to deal with and his pumps and purse are a hoot. I think they'd be great for a second system in the bedroom, with great WAF I would think. ;-)
