PS Audio BHK lacking..

if $10k worth of gear cant beat < $1k step #1 is to measure and baseline that it is working even remotely properly.  Both performance and settings (eg..; Bias)

The day I bought the BHK here on the Gon I ordered a new set of stock tubes from PS Audio.  They showed up a little while ago. I have them in now & they made a big big difference. It's starting to happen. I'm looking forward to trying some of the tubes you guys mentioned.

Next is what should I expect to pay. There is a set of Telefunken 12au7 on line, new for $400.

What kind of qualities do you enjoy most in your music and what music do you play most often?  Easier to recommend tubes knowing what you like....warmth, speed, soundstage, strong bass, lots of air, treble sparkle, etc...

I’d go with strong bass, soundstage & air.  Mostly old rock, country, & now classical because it is well recorded.
