Conrad Johnson Premier 12 tube monos

The Atma-Sphere M-60 MkIII would be an outstanding match with your Coincident Victories, as Jtimothya suggests. Authority in the bass with excellent resolution and quickness, plus a midrange timbral accuracy that few other tube amps match. Don't let the 60w rating fool you - with a 14ohm load, this OTL will exercise more control and deliver more power into the Coincidents than other nominally higher powered amps, and you can't beat the Atma-Sphere's transparency, resolution and harmonic truthfulness.

Get yourself a Music Reference RM200, unless you want the overly warm sound of the CJ 12's... Plus the Music Reference is fully balanced design. The Music Reference is more transparent than the ARC VT100 MkIII and way cheaper to retube, plus you can try Kt88's or Kt90's to take it even a step further depending on what you like and system synergy.

You might want to audition the PrimaLuna KT-88 monos.I would definitely upgrade the input and driver tubes,along with an after-market PC.Check their audition policy,don't know if there is a re-stock charge.For $2700,the other upgrades might leave some leftover cash for music.
