What to put under my VAC AMP/ PREAMP??

HRS is all custom made, so no demo there, I've talked with them about it before. Critical Mass is something I'll check out as well, although the Shum Mook are intriguing because I can use my existing rack shelves with them...

I use Mschina Dynamica Promethean springs sandwiched between HRS but I already owned them. Maple boards will do nicely in this set up. Herbies isocup/balls directly under the components

As long as we have a few Phi 300.1 owners here, do you guys run in Triode or Ultralinear?

Ultralinear for me.

I'm really torn between the two and tend to go back and forth...what about Ultralinear do you prefer?
