Solid state to tube

+1 on the Quicksilvers.

I have the mid mono monoblocks. They are wonderful and have no problem driving my 90db efficient KLH 5s to fairly high listening levels. They also worked very well with some Snell Towers I had before.

I find they have plenty of slam and in fact were better in this regard and have better bass than a Belles 150a power amp and a Luxman integrated that I previously owned...both with over 100W per channel solid state. It provides wonderful bank for the buck.

Also easy to try different tubes. Want slam...run KT88s.... want a lusher presentation,,,,run EL34s which is what they are voiced for. Also they are very well built and have been utterly reliable over the 5 years I have owned them which is more than I can say for some Cary and Audio Research gear I had.... albeit a long time ago. Some of the most musical amps I have owned in over 50 years in the hobby. They are keepers. BTW I also run a tube preamp, Conrad Johnson.

👍👍.  Nice system as well. 

Have the speakers ever been recapped? If not, start there. 20 year old caps are well past their sell by date. Replace ALL with polypropylene or PTFE.

Going to a dealer is a waste of time as they do not have your speakers, cables, room or the rest of the system. You might hear differences, but they will likely not travel home.

If the speakers are ported, some tube amps may not mate well due to the impedance curve.

I’d add the VTA gear from Tubes4Hifi to the list....really excellent stuff that’s fairly affordable.

It's not really excellent stuff. See VTA M-125. People have all kinds of problems with them and have written after ZERO support from Tubes4FiHi. If you complain on their forum, they axe your account. A lot of their advice is just plain wrong!

Thank you and likewise. You certainly have an audio system to be proud of and I’m sure does justice to your music reproduction.

Linear tube Audio all the way in this case for good value  to do the job well. Read their tech literature to see why. Ref 3a speakers are not all that tube friendly as they may seem on paper from what I have gathered over the years from owners. Results could vary widely with various tube amps.
