Tube integrated with real bass. Does it exist?

8 Watts and great bass with the right speakers? That's incredible. Air Tight and VAC are on the very top, as I understand. Lamm doesn't have integrated, Vladimir Shushirin just doen't accept the concept, I guess. But I bet his integrated would be a success.
Anyway, the other day I was listening to my modest set-up, and everything sounded quite well. In fact, everything sounded wrong. And the cause is quite clear to me - it is solid state. Tubes all the way for the future serious upgrades.

I would bet on the Rogue Cronus Magnum II KT120 Integrated to fill that bill. I have the Rogue Stereo 100 and it's very powerful, extended and articulate in the deep bass. My friend has the Cronus Magnum II and it's got great bass too. And it sounds quite musical and detailed in the midrange and highs as well. List price of the CM II is $2495 and I don't think you can go wrong.

I use my Rogue on the Legacy Focus SE speakers, which has two 12-inch woofers per speaker that extend below 20Hz... I previously used very good solid-state amps to power them but I like the Rogue KT120 amp better--yes, even in the bass!

I will say that regarding most OTL tube amps, they do have ample bass if they provide enough power, but they will also accentuate the bass quite a bit at the speakers bass impedance peak, which is neither natural or real--only overblown.

Sorry Inna, I didn't see tube in your request. My fault.

Amazing how many here bit at what is a silly and pretentious question (OK…I'm biting)…but I'll state (or re-state) the obvious: the frequency range of most well designed modern tube amps provide plenty of bass if matched with speakers designed to reproduce it. Also obvious is the benefit of a good sub to any system other than one with a large and efficient main speaker (Tannoy? ZU? Vintage Altec?). If you have the clams for it, the Rogers integrated KT150 200 watt per side is pure muscle…I've heard one…pricey but cool. Tube amps, if they have some cajones in the design, seem to have more muscle than SS amps, but I could be basing that on how they sound…weirdly.

If I were to go with an integrated tube amp to replace my Luxman 505ux (which has much better bass response with my Harbeths than the Rogue Cronus Magnum), I would check these out.
