Tube amp with SS like bass

this is the 10 year old father of the VK-55 and has deep tight bass. Looks like new, has low hours on the tubes, and has original box and manuals, I'd let it go for $900.

Of course I meant the Audio Research 100.2 SS amp. May give me the best of tubes and SS. But do I really get an advantage over my VK-200? Guess I'd have to buy and try.

Again trust me Rogue 120's or VTL 300 if Big time power is needed.

Atma-Sphere OTL amps deliver the tightest and most articulate bass of any amps I've heard; all the positive benefits of solid state control with the ability to reproduce harmonic overtones, timbre and resolution only seen with the best tubes. Unfortunately for your budget limit, you'll probably not find an M-60 MkII under $2500 (and the MA-1 for considerably more). But if you're able to stretch your budget and if you have a speaker compatible with the M-60, I think you'd find what you're looking for.

Tvad, you are right on the wall-shaking part - my bad analogy. For me, bass is so important, I would not wish to listen to a speaker/amp combo that could shake the walls if it could not do so with utter control and precision. However, the ability to control the bass is also a matter of sound pressure level, which begs the question of environment. With a smallish room, a nearfield listening position, and efficient speakers (with a relatively high and stable input imepedance across the frequency spectrum, including the bass), any number of tube amps can drive the speakers to satisfying levels and deliver beautiful taut bass. With small-ish bookshelf-like speakers (on floorstanding bases) which only go down to the mid-40Hz region, in an 1800sqft room with 22ft ceilings, I would venture to say the same amp might not deliver the goods.

Gooddomino, I would wait until you have gotten your new speakers to look for amps. Depending on what you go for (PD-series, Freedom series, or something like the Linbrook), your possible amp selection would change considerably. The PD-15s would have pretty darn good bass with some 845-based amps; the F-5 would need a lot more power to drive that room (partially depending on how far away you sit).

If dying to get big tube power (with great bass control) for a low price, the VTL 300s mentioned might do the trick.

Best of luck!
