The Backert line of preamps are all absolute gems. They use two 12AU7 tubes which are auto biased . Tube rolling is easy and the results of rolling with this preamp are palpable. Decware, despite the wait makes wonderful low power tube amps. Wyetech Labs is in the process of selling their remaining stock of ferociously incredible SET mono blocks due to the death of founder Roger Hebert. These are all tube based products very deserving of investigation.
Solid state to tube
I have been a solid state guy since my start in this hobby. Over the years I have built a few systems and have used mainly older YBA seperates pre and power for my front end.
I also have a pair of musetex MT101 mono blocks from Meitner audio which I use as well.
My speakers are reference 3a lintegre
I am thinking of moving to a all tube system
. However I have little experience
I have looked at Quick Silver and a small boutique builder called Will Vincent. Have not heard anything yet. I thought I might inquire here first for any suggestions from tube savvy members
