My stable of tube amps is down to a Sonic Frontier SFS-80, and Allnic M-3000 Mk. 2's. SS amps include Bryston 7B, Krell 300, Nad M33, Topping LA90 (to see what the hype was about), and I have a local tech putting together an amp with the latest Purifi modules for me (mainly to help him out). Like most I have had Macs pass through, Pass as well.
In my main system where I have the Lyngdorf, if I set it to flat, the tube amps are unmistakably different. They don't sound the same as each other either. The solid state amps sound pretty much the same, until you push them hard. The Krells have a ton in reserve. If I let the Lyngdorf do its thing, the tube amps and SS amps sound surprisingly similar. They are a bit warmer still even though the bass is not quite as good. If I cross the mains over at 80Hz, the difference gets even smaller. (We had long lock-downs up here in Canada!). Then I looked at the correction data from the Lyngdorf. It was the same for the solid state amps, but different for the tube amps. It should have been obvious, but till you see it in your room, you don't expect the response to be that different for a tube amp.
The Allnics are art, and the Sonic Frontiers is part of Canadian history, so I don't think I will part with them, but they are relegated to less used systems, though with entertaining, the Allnics are getting used more. Tube amps are conversation starters.
