As a long-time owner of many McIntosh components, I concur with theo. What power amp can you get for $3,500? You could look for an older but in very good condition Mac amp with autoformers. I use a MC2205 in a Martin Logan system. I am using the C2300 preamp. I also have a MC2255. Don't be put off by their ages...if they have been upgraded, you won't be unhappy.
