300 Watt Tube Monoblocks

Why?

Agree with others that the cost of maintaining this many power tubes would be nuts, especially if you listen a lot or have them biased hot. You're talking some real $. Plus the insane weight and possible repairs and shipping...just a bad idea.

I would avoid this path for the reasons mentioned.  After owning some high-powered tube monoblocks and dealing with tubes melting down, the cost of tube replacement, repairs, etc. I would go solid state for amps and have the tubes in your preamp and phono stage.

One conversation that sticks in my mind is one I had with a builder of some really great tube phono stages and preamps.  I asked him why he didn't also build tube amps and his reply was "I don't want to be in the repair business".

I remember a telephone conversation I once had a long time ago with Andy from Michigan (Vintage Tubes); he spoke in an almost orgasmic tone of voice about the sound of 200 watts of class A power . . . he was telling me about an amp he had just rebuilt,; I think it was a Jadis.
