Tube integrated with real bass. Does it exist?

Dorkwad,

The KWI-200 is a neat product, but entirely solid state, so it does not match the OPs criteria.

I took a look at the Modwright, it's transistor design not tube.

Cary CAD 120s amp, maybe bigger woofers is what you really need.

Define "real bass". Don't most tube integrated amps have it? At least if used in a smaller room and/or with suitable speakers?

The problem is more likely that there are relatively few speakers that can do bass really well with most tube integrated amps. Ones that can are likely very big and very expensive.

When the amp has limitations, the speaker has to take up the slack (easy load, high efficiency, etc.). That's the case with tube amps.

With SS amps its the opposite. Speakers can be smaller and less efficient, which the evidence indicates is what most people prefer.

Doesn't make one better than the other necessarily... just different "paradigms" as they say.

I think the PrimaLuna Dialogue Premium HP (high-powered) would do the trick for you. You can use EL34, KT88, KT120 and KT150 tubes and run it into ultra-linear mode or triode. It will do 96W X 2 into 8 ohms running ultra-linear with KT150 tubes.
