Tube amps with BALLS in the low end registrer ???

I've been very pleased with the bottom end on my VTL MB-450's, full and extended (as John mentioned they couldn't be called moderate power, though in triode mode they're about the power you're looking for).

why not just biamp? get a 50 to 100 watt tube amp for the top and a mega watt solid state amp for the bass. you might could save some dough by going with a digital amp for the bass.

My system have a huge balls.
And I think most of us like it soft and wet.
Bi-amping might be the way to go.....for you.

Cheers

I second Kaicable's response re: Kronzilla DX. I have the KRonzilla SXi with half the power of the DX (50 watts/channel) using 90db sensitive speakers and the way the Kronzilla grabs hold of the low end and still remains extremely musical is astounding. Take Bela Fleck's Flight of the Cosmic Hippo for example. Thinking of the bass on that cut makes me smill.

I think you'll find that low end response with tube amps will correlate with output transformer design. VTL amps excel in this regard. I have a pair of VTL 300 monos which provide the most controlled and musical bass of any tube amp I've tried. They built a few model options in the 200-450 watt range.

Must say I'll add my agreement with John that 200-250 are hardly "moderate power" but I would say for ANY amp.
