I am in the market for a McIntosh preamp to go with a MC452 amp. I have 2 turntables, 2 CD players and a cassette deck. All of my TV and DVD stuff goes through a different system. It looks like a C47 is the match being offered new. I'm not sure I need all the bells and whistles it has, but who knows, I might in the future. Any advice would be appreciated. Thanks.
