Best U.S. made integrated tube amp under $2500?

Consider going vintage. I'm thinking of a Fisher or Scott receiver, or an Eico integrated. You should easily be able to find updated/upgraded version of these products at well below your price level. Also consider a Mesa Tigris. Unfortunately they don't come up often and sell very quickly.

You can use EL34 in Magnum version. You can email Rogue directly. They are very helpful.

There is a Cary sli 50 listed now for 1500.00. It uses el34 outputs. 30 watts class A so it runs hot. My favorite amp. It has a dynamic exciting sound via Triad speakers. No remote control though.

Check out Tube Audio lab - Hand-made in California.
$2500 will get you one heck of an amplifier.

As to American-made tube integrateds, I think the VTL IT-85 and the Manley Stingray are great, and easily found used in your price range. As other posters have suggested, Cary and Rogue are also decent performers (in a number of models) in your price range. All of them will have a slightly different sound.

Buconero117,
I am interested in this legislation. The question is if it is mostly built in one place (like China), bought FOB for $200, is shipped to the US "mfr" who takes it out of the box, inspects it, gives it a good rubdown with a dry cloth, adds a fancy brass plate on the back, and reboxes it, and sells it to his distributor for $600, how much 'content' is US and how much is non-US? I foresee no issues whatsoever at the low end, and a lot of potential issues at the top end.
