"Good tube Integrated Amps"

pear audio blue Classic intergrated at 4K ,

A must listen is the Audio Research VSi60 or VSi75.
They punch well above their weight, and have the solid ARC house sound.
I might be selling mine (VSi60) in the coming weeks, but it would only be to go to Audio Research separates. But I’m gonna let it take a swing at pushing my Wilson Audio Sashas (in bound) when the arrive.

How much power do you need.   Eastern Electric makes very nice products for the money.  They are built like tanks and some have many features  for tweaking the sound like my M520 25w/ch but can drive small Maggie's in a small room no problem .   Bill at Morningstar audio is excellent to deal with. 

PM me if you decide to sell your VSI60.  I had one a few years back and really regret getting rid of it......

I almost got Cronus magnum 2 but kept seeing so many on secondary market figured it wasn't a great sign. I wanted Manley, but too expensive, same with the Cary sli-80...I ended up going for primaluna Classic, which is a great sturdy amp that holds its excellent value, haven't seen those on secondary market really...I do wonder what more watts would sound like sometimes, but look forward to upgrading to the KT-88s...the primaluna supposedly lasts longer, putting less stress on the tubes...
