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.

If you enjoy the sound of the Krell (great product), then a recap is going to bring the life back!  Getting over 25 years out of something is an awesome feat and shows the value you have received from such a product!  

Looking forward to your thoughts on the Don Sacks pre.  I'm always open for good recommendations.  

In the end, it's your ears and no one can argue with that.  :-)

I am going to second Scott_w's recommendation for a Sanders Sound Magtech amp.  It's especially made for electrostatic speakers like the 13a's.  I have been using one with my Martin Logan Montis speakers and the combination is a true dream!  I have tried amps that are thousands more from my local dealer and only have to send them back, because none could touch the Sanders Sound.  The Magtech has been an Absolute Sound best buy for many years.  Mr. Sanders builds them in CO and has a generous 30 day trial period.  At $5500, it is truly a best buy and likely the last power amp you will ever buy.  

For preamps, there are more options I feel.  I personally use a Classe Sigma SSP processor since I also need home theater duty in the same room.  It works great for my needs.  But eventually, once I move to a larger house with a dedicated hifi listening room, I will likely get a true two channel preamp.  Top contenders are ModWright LS 100 ($3750), PS Audio BHK Signature preamp ($5999) or if I am on a tighter budget a Backert Labs Rhumba 1.1 ($2250 on clearance).  I've listened to the Backert and ModWright at HiFi audio shows, so I know they are good.  The common thing among all of these is that they have tubes in the output stage.  I think a tube preamp like these marry well with the solid state Sanders Sound Magtech.

Kind regards and best of luck,
Jason
