I think this is true. It's still cheaper to produce several hundred
watts with an old tube design than to do so with solid state devices.
Although that may not continue for long, as certain tubes become
unobtainium, and solid state devices slowly get cheaper.

I think the price point for this type of equipment has shifted upward
to the point that solid state amplifiers are practical in the market.

Looks like just the continuing evolution of electronics.
