Upscaling Speakers, Downscaling Amp...What to Do?

Given that the Perspectives' twin woofers will make a bigger demand on the amp's bass control, switching amps along with the speakers may be a good idea anyway. Since Rogue has already passed your "proof of concept" tests, check out a pair of Rogue 150w monoblocks on the A-gon classifieds at your price point.

Also, have you asked Joseph Audio for a recommendation? I notice that their online specs don't specify sensitivity or power handling. Power range and damping factor recommendations would be helpful.

Which class D amps have you heard? Just curious. I love ARC's tube gear, but I heard their new class D amp a couple years ago and wasn't all that impressed. I keep holding out hope that some class D's claims will be true. E.g., I'd love it if the Red Dragons truly deliver SET sound in a powerful class D amp.

Back to topic, hoever, given that you like tubes + Joseph speakers, you should probably stick with tubes or class A solid state, but finding affordable 100wpc+ class A SS could be a challenge.

If you like VAC, you'd probably also like VTL. I've head VTL with Wilson speakers and the combo was very impressive. Right now there's a pair of powerful VTL monoblocks on the A-gon classifieds in your price range.

Also the all-tube VTL-150 stereo amp is almost in your price range ($3750 list). You might find a demo or get a discount to put it into your range. It's 150 wpc into 8 ohms.

I have a good room to start with. It's quite large at 32' X 15' X 9' (avg...it's vaulted). Room corners are complex since this is over my garage.

With a room that size, it's no wonder you'd want to go from the Pulsar (stand-mounted 2-way) to the Perspective (dual-woofer floorstander). As much as I love a good amp, there are some things an amp can't do, and that's one of them--increase the diaphragm area to fill a larger space.

With that big of a room I'd still use the subs, but cross over around 40 Hz.
