Good SET Tube Amp for $1500?

These exceed your budget, but would probably be a great pairing with your speakers . I would check to see if any other users of your speakers use OTL's and how they match up. If they don't match perfectly, consider using autoformers between them instead of speaker cable ZERO Autoformers.

Jax2: You're a DAWG, man! That's a compliment, you know! I'm the same way; I like bottom feeding--not that there's anything wrong with that ^_^.

This is a great amp for the price.
I own a SET amp modified by Roger Modjeski
is it's the greatest investment ever.
Ran in on JBL horn system and it blew the
Sun Audio 2A3 away especially in high frequency
and bass extension.
I tested with Sylvania Black plate 2A3
vs GE EL84.
Roger makes one of the best amps
