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.

Tube preamps with stats are magical. :)

However, OP, you have one cold system! :)

AR and Krell to my ears are pretty analytical and lack warmth. Maybe consider a CJ preamp if you want something mellower, and juicier. I find they are IDEAL with ESL's.

Best,

I remember hearing Krell electronics with a chrome faced preamp with three large chrome knobs with blue lights are the controls.  Cannot remember the brand name, maybe some else can help me out. It was a very nice match.  Probably can find one used some where.Happy Listening.

@scott_w   Your statement against using tube amps with Electrostatic transducers is not true in all circumstances.  The best Martin Logan experience I have ever had was listening to a pair of Montis driven by a top notch all tube Audio Research amp. Dynamic, sweet and open!

Before going to far, check the manual of the Krell.  I use to have an older Krell 200 FPB stereo amp.  When I added a tube pre, I had to open the amp up and remove a small jumper(manual switch) connector.  Something about tubes damaging the amp.  The information was in the manual but the location was not so I called Krell and I performed the job with the tech over the phone.

I had Maggie 3.6Rs powered with a Blue Circle 2.1 pre. Absolutely golden. Check into blue circle.
