McIntosh .. One step back

The preceding models you're looking for are the c42 preamp
and mc352 amp. This will get you the same sound quality
as the c46/mc402.
Good Luck

You also might start frequenting you local McIntosh retail outlets(s) as many McIntosh owners with upgrade fever often trade in their old units for the latest and your local retailer will often perform lots of tests and updates much as a quality used-car dealers do. You need the sales people to be calling you when the goods arrive so you can give them a listen for yourself.

Contact AudioClassic.com they specialize in MCIntosh used and refurb. Great people to do business with. Second teh MC352 I have one and love it. Many pre ampos to look at the C712 is a good peice if you don't have a lot of gear to hook up. I think it only has 6-7 inputs and 1 tape loop.
I started there when I bought my first McIntosh.

I second the C712 idea if you are short on cash. I've had one for the last 3 years and love its simplicity and silky sound. For the amp, it's hard to beat a MC352. Good luck! Arthur

i have a mx132 paired with a mc602 for a 2 chanell setup. any thoughts on this combo?
