Tube amps under $7500

@ditusa +1 Also, mfr of my SS amp recommends balanced, so those are the cables I have and there are enough tube amps in that category that check my boxes.

@akgwhiz Power amp, not integrated; 70+WPC; silver preferred although wood will do. Down to a short list now thanks to many helpful advisors.

I would add to audiotroy's list:

1. Dynamics--tube gear sounds more alive and dynamic, particular at low volume.  Solid state has to be cranked up much louder to come alive.

2.  Natural/realistic attack/transients--the initial attack of a note sounds more natural and not as artificially hard or brittle.

Many of the tube amps that have XLR input jacks have them for a convenience for people with balanced cables, but the circuitry is not fully balanced.  If you have balanced cables and a piece of gear does not have XLR inputs, you can buy adaptors so you can keep the balanced cables.  This really should not be a limiting factor because the vast majority of tube amplifiers are not fully balanced.  

@hickamore I own Primaluna monoblocks. Pay no mind to the bias against PL products displayed on this forum. The bias is because they’re built in China. A segment of these people believe that anything built in China is junk. But another fact is the majority of these people have never owned the product. So how would they know anything about the products? Exactly. My amps are over 15 years old, self biasing, and operate as if they’re knew. Go figure. 

For the money, it would be difficult to do better than a Don Sachs Kootenai KT88-based amp.  A few are available at the moment.
