Does anyone own a Primaluna Dialogue Premium HP power amp & Primaluna Dialogue Premium pre-amp using ElectroHarmonix power tubes, 12au7 tubes, or 5ar4 rectifier tubes? Trying to dial in my system for the “classic rock” sound, want to know what other people have tried and are using. NOS is so much coin, most of the new production stuff i have heard is very close,as long as it’s tested & matched properly. Need input, Thanks
