Tube integrated with real bass. Does it exist?

So something does exist. That's good. Modwright is mentioned quite often on this forum. They must be doing good things.
Two inputs are just enough - one for phono and one for deck. You can run digital through deck monitor if you have to have it.

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.
