Tube amps under $7500

@audphile1  Rogue now definitely on the list. Had forgotten about them but I do know a dealer pretty well.
@biglou13 , If this means I am wasting my time shopping under $15k, well, so much for the experiment. You did notice I am talking amps, not preamps?
@hilde45  Know nothing about Quicksilver; will research & explore before making any decision.

@curtisvill I am not thinking integrateds at this point as I like the flexibility of separates. Maybe when I enter downsizing mode in a few years.

My experiences with Tube Amp's both Pre and Power is that they are bettered in their  End Sound when seated upon a Isolated Plinth.

After numerous trials with materials as a Base Board and Footers, the one which to date has made the biggest impression at Tidying up the Sonic being produced, is a Phenolic Resin Impregnated Densified Wood Board, with Audio Technica AT 616 Footers.

A board ss the one suggested is not too difficult to acquire. I am also confident Footers can be found to be equivalent in performance to the 616.

I strongly suggest a support for the Tube Amp is given consideration.  

If you are looking at integrated amps, take a look at the Synthesis A40. Sounds fantastic and the integrated DAC is amazing.

Audio Research, Conrad Johnson or Macintosh or go home . You can always resell them at a decent price . Good luck selling that Prima Luna with a huge lost . 

Rogue ST-100 is an excellent amplifier and should work great. 

 Have you heard Prima Luna also?  

No!

@soix, I love the romantic, tube-y sound, with realistic deep bass. Always relied on preamps with class A-A/B amps before, but that could be just habit or bias or maybe I forgot why. Legacies are Signature SE, best bass presentation anywhere near the price; would consider upgrade to Focus if justified; can go no higher given my room constraints.
@ ditusa I found Rogue tube preamps (5 & 7; heard same about 9) rather sterile, so never explored the amps and forgot they were out there. Have you heard Prima Luna also?  

@hickamore,

What sound characteristics are you looking for, which model Legacy do you have, and are you looking for new or used?
