@@dbb - my tube pre amp is made by response audio / musical Bella ( formerly purity audio) the engineer or builder Bill Baker was/is working for Raven and build his own stuff. The foundation preamp the he built me came stock with a solid state rectifier I Bill if he can make it with a 5ar4 rectifier, so he built a separate chassis that power the rectifier and also installed a 12v and 5v Lp into it to power a streamer or Dac. The foundation preamp is very quite, smooth and picks up alot of detail. I'm feeding the the preamp from the puritain 156 with Aq hurricane high current. Feeding to the Gallion TS A20 power amp ( also a very good peice of Kit)
Currently using wathan cyro treated rectifier and 6922tubes great results.
Now to the mustec preamp with 200 hrs of burn in. Fantastic, sounds like a tube preamp, when I hit the 500 hrs recommend burn time of the preamp I will report back , I also want to AB the two preamps.
