Audio Research REF 750 pre July 4 FIRE WORKS. TUBE ARC.
I have an audio research VSI 60.  It burns through tubes very fast, and has to be repaired every time.  I don’t agree this is a tube amp issue. This is an Audio Research design flaw/issue.     My Primaluna doesn’t even blow a fuse when a tube goe... 
Rolling KT150s in Primaluna hp integrated
I just bought a quad of KT150s from upscale audio.  I initially tried them in my audio research VSI 60.  They have a little more bass than the KT120 but the amp is still cold, clinical, and revealing.  Not really worth the upgrade in this amp unle... 
Audio Research in Receivership.

Primaluna 300 integrated running 6L6 with high bias switch

Leben CS 600 tube rolling
6CA7 is a drop in replacement for EL34 and sounds like an EL34 on steroids.

KT66 should be a drop in replacement for 6L6.  KT77 is a drop in replacement for EL34.  KT88 is it’s on beast.  
Cary Audio VT-500 tube phono-stage preamp
I have had a Cary tube headphone amp for years.  It really responds well to tube rolling, but is not super revealing. It is a pleasure to listen to.    I suspect you are looking at a warm phonostage, that may not be the most detailed. Hopefully s... 
What sonic qualities connects to you deeply and emotionally?
I only care about the music, they could say about anything if the music is good!  
Speaker upgrade for Primaluna EVO 300 - Looking to find some audio nirvana bliss!
I think I’m going to go with the KLH model 5.  The reviews are positive and I really like the look.  I know these aren’t as high end as most of the suggestions above.
