I started with tubes and went back and forth with SS until just a few years ago when I bought PS Audio. Their BHK line is all Hybrid, the Signature Preamp and BHK amplifiers have a tube input section and a MOSFET transistor output section (mosfets put out a warmer sound). I’m getting the warmer sound I was looking for without all the heat of lots of output tubes. They just discontinued the BHK preamp and the BHK250 and300 amplifiers so you can get them at half price or less.
If you have the money, Audio Research makes some incredible stuff (mostly tube) and they are built very well! The sound is probably everything you want, but there is a lot of heat from the power tubes and depending on your room size and where you live can heat up small pretty quick.
Another idea would be to get a tube preamp and a SS or Hybrid amplifier. Depending on how loud you play your music might be the best solution.
All the best.
