Why don’t tube amps sound like tubes anymore?

I was thinking about this more and what I like about my amp is not that it's warm and "tubey". It's that instruments and voices have more tonal color and saturation. They are more dimensional and seem more "there". That about sums it up to me.

@jond. Yeah this is what singled ended amps do for me as well whether tube or ss.
If you get the opportunity listen to the Pass stuff. I believe his I25 integrated is s.e. First set of watts run A so it does not get too hot.
Also, there’s the French company "Valvet" that also gives this impression to me and that is also an ss unit.
Tough to find however.

Maybe it's the switch to solid state rectification in the power supplies.  The old amps that used tube rectification, chokes and less capacitance had more sag, which added more warmth to the sound.

Hello, I agree with you’re opinion about most of the tube amps made today. This is happening because designers know how to make tube amps sound more accurate than the designs yrs ago. Also, many parts like capacitors made today are cleaner and better sounding. Another factor is the type of power tubes being used today in comparison to the past. There are some companies that still make musical sounding tube amps. Like Canary Audio and Consonance. For me, I still stick with power tubes I’m familiar with and are known to be musical. 300b, EL34, KT66 amps etc.
