@mcpherson I wonder what's in those Super BMR to make it so expensive. $3,500 each. $7k for a pair. The HT towers have the same drivers and 2x the amount of the Purifi woofers and only $4500~
To answer your question. I tried a tube amp, 55 watts / channel. Lots of watts as far as tubes were concerned and that wasn't enough. It sounded marvelous but the tweeter wasn't getting enough power but it sounded subdued.
But like I said, the amp has to be really good in sound quality and has to be quite powerful. Idk how powerful the Rogue Magnum 3 is, 100 watts seem sufficient. I believe it would be a good match.
I don't have the BMR anymore, I only owned it for 2 years. ATM I have a Coda S5.5, the Coda is powerful and sounds sublime. I'm sure it would be a good match for the BMR too.
