GT tube suck. I order a platinum grade GT 12AX7 from upscaleaudio, one of the two make noise the second day and Kevein won't even allow me to exchange it. I try many other 12AX7 from GE, telefunken, sovetk. all sound better than stock one and no noise.
Aesthetix Calypso, Tuberolling questions?
What results have owners of this preamp had with different tubes used. I'm running stock tubes into a pr. of Parasound JC-1 mono blocks now and the sound is very good. Would like to open up the treble a little if possible without messing up other areas. Any info on what people have tried and to what results would be of great help. Thank you
