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.
Need a preamp with tone controls!
OK, most audiophiles would say I shouldn't need tone controls, but I have a good system that plays QUALITY recordings beatifully, so much that it makes me not even want to listen to many of my 70's & 80's stuff. This comprises the largest part of my collection. So I've been looking at McIntosh preamps...great tone controls/equalizers, etc. Any others out there of audiophile quality???
