Which preamp to go with pass labs x150.8

@mbmi - Have you heard the Audio-gd and what preamps are you making your statement against? Also, the reviewer offers zero context as to what against that preamp is the best ever he's heard

@runwell  "I do not suggest a tube preamp with any SS amplifier,as it is not a good match."

Have you had a tube pre and SS amp in your system; if so what were the components.  I have a Modwright LS100 tube pre and KWA100SE solid state power amp in my main system, sounds just fine.
