Amp for a tweeter


Hi
I’m looking for suggestions.

I’m moving towards a 3 way active crossover system. I’d like to have a dedicated amp for the tweeter. I’m looking for a low power but low noise floor. Is there an amp on the market dedicated to drive only a tweeter?

The midrange will be a First Watt J2 and the crossover will be via First Watt B4.

I primarily listen to chamber music at low volume but would like to improve my system for symphonic music.

Low power amp has lower signal gain than high power amp. How you going to match it?
I run a PP EL34 amp (30 Watt) on the woofer/mids and a 2A3 SET amp (3 Watt) on the tweeters. Works for me.

He did say he was going to use an active xover.
