Selling off Tubes for Solid State, A Cooler Love Story?

As usual, @jjss49 is plugged into my brain so I’ll just echo his thoughts.  Read the AGD reviews, and they’ve recently launched a stereo version that’d be worth a good look.  The only other thought I have is there are some very good Class-A amp manufacturers that offer their amps with a hi/low bias switch (Clayton, Plinius) that might give you a nice compromise.  Or, maybe look at Valvet amps that I’d view as Class-A lite and may give you what you’re looking for depending on the sensitivity/power needs of your speakers.  Just some other food for thought, and best of luck. 

Modern solid state is voiced  midway between the golden sound of tubes and the crisp cleanliness of s/s

as many experienced hands have noted, modern solid state amps at the upper tier use various technologies and techniques to produce a sound that gives the best of both

perhaps the most articulate among the makers is nelson pass, who describes how he and his crew dial in small, desired amounts of even order harmonic distortion into their amps to provide that tubey goodness our ears crave in reproduced music -- all the while producing the tuneful, deep, taut, powerful bass that can only be approximated by the tippy top massive tube amps

well made, powerful class a amps do the same, as does alberto at agd with his brilliant take on ga-n tech - now, powerful class a stuff still produces a good amount of heat, but there are no tubes to replace, bias, burn out, and so on

a really wonderful time to be in this hobby

Class A is the absolute best sound quality and contrary to popular belief they don't get that hot. A Class A or A,A/B power amp paired with a tube preamp is always a good combo.

Belles!
