Switch preamp?


I've been an audiophile for over 5 decades and consequently collected a hodgepodge of equipment that I've mixed and matched with a degree of luck. My current listening room system, and most likely my last, consists of AR's (ss) LS10, Krell's KSA 250S, Martin Logan's 13a -- my latest addition and the reason for my question -- and AS Liveline's chord and speaker wire. I listen to most genres equally in CD, vinyl and Tidal.
It is my understanding that electrostat speakers perform best when utilizing tubes. I am not prepared to switch out my Krell but would consider the Audio Research since it's solid state.... and the clicker has gone missing. Ages ago I owned a Conrad Johnson with another system and have fond memories of its mellow sound.
So, does it make sense to replace the AR with tubes spending in the vicinity of $5k in the used market, or do I have a gem and should leave well enough alone? I am happy with the sound but these are my first electrostats and do not know what they're capable of. The closest audio store is 5 hours away so I count on smarter minds than mine to guide me. Thank you.

I guess it is just of these audiophile myths. I would stick with solid state, as did Quad's Peter Walker, once he had designed his first solid state amplifier. I drive my Quads with a Quad 606-2, and that is fine, even if I might one day upgrade to the QMP monoblocks for more power (power is king).
No reason to expect any sonic improvement from changing the Krell (your electricity bill will be lower with a pair of bridged Benchmark AHB2s, however). Just get it recapped and you are good for ages again.
