Suggestions for a tube integrated under $3000

A real bargain would be the Aronov LS-960I if well maintained, and about $1200 pre-owned.
It has a most natural, musical character, together with the best ability to optimize bass accuracy and extension anywhere near this price range.

buying a Cayin or VAS is a must, great sound, great value. I own four of them, never a problem. Consider buying used if you can do a pick up, for cash.

I've heard the SLi-80 and the Prologue II on those speakers . I much prefered the Primaluna over the Cary due to its better extension on the top .

Good luck

There is only one I would buy new at that price - decware flagship - zen Torii mkiii. Amazing bang for the buck. Buying used I would look at CJ ca200 or Pass labs class A 30 watt integrated. I have a Simaudio i5.3SE I would sell for $2500

What kind of power do you need? I've been enjoying the heck out of a Melody MK88 which is 32 watts of class A power. Truth be told, I think I prefer it to the Decware Torii mk3 I owned before it.

I did a write up on it in the review section here.
