Johnny used to sell the Music Reference RM-9 to 2C owners, a marriage made in heaven (owners of that pairing live happily for years). Alas, the amp is no longer available, and is hard to come by used. The RM-200 might be even better with the 2C, as the amp likes low impedances more than does the more traditional tube design of the RM-9. RM-200 Mk.2's can occasionally be had for around $3,000, the original for $2,000. Worth waiting for.
What would you buy
I am a tube lover. I currently have a Rogue Chronus Magnum and Vandys 2 sig E. I'm thinking upgrading my system. I believe I can get 1K for the Rogue and add 5K for a total of 6K available to spend. planning to keep the Vandys but I feel that my taste desires a little more bass than what I'm getting now. Vandys are great in the mids , voices etc but it lacks some deep bass. The Rogue doesn't have an output for a sub woofer. Musical taste is classic rock, jazz and blues. Here is the question with 6K to spend in amp/pre, integrated or mono/amp, what would you buy?
