Need a preamp with tone controls!

FWIW, I bought a used McIntosh C220 tube preamp from Audio Classics in 2010.  I remain very pleased with this preamp.  I rarely use the tone controls, but they are well implemented and defeatable.  Finding a preamp with all the features of a Mac is possible, but few offer all the features, like a balance control, remote, tape loop, etc.  My only criticism is that it is needlessly difficult to remove the case cover, and the strain of long ICs from the preamp to the amp killed one of the three pairs of main RCS output jacks.  Not a big deal, I just switched to another output.  But I would suggest supporting the ICs so as to relive the strain from the output jacks, like I did.

Luxman 900

I have one of these, honestly, LOVE IT

Triode Corp of Japan makes a couple of preamps with four tone knobs; 150, 400, 2k, 10k; +/- 6db. The eq circuit can be fully bypassed if you wish.  

Many options out there, but i've heard the octave Hp700 in which it's an option & The AVM ovation 8 series pre. Both are very good, although the HP700 is expensive but top notch stuff.
