Tube integrated with real bass. Does it exist?

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 have heard "real" bass with ARC, ROGUE, and VAC integrateds driving PSB, Magnepan, Sonus Faber and other popular speaker lines at least in a modest not large showroom. 80w/ch + or so needed. No low pipe organ notes in any demos I've heard though so can't speak to those.

Those are the three lines I have heard and like most that I would go for. I'm sure there are others.

I bet a lot of people would like to see Atmasphere offer an integrated.l I think I asked Ralph about this once and he said it was a possibility.

Its worth noting that they may be all you have to go with but efficiency specifications are quite loosy goosy typically and hard to bank on either way.

Usually, if speaker is small, chances are bass will be limited with most tube amps. Those speakers that can do extended flat bass out of a small box always require more power and current to achieve it. No free lunch here that I have ever seen or heard. If it appears too good to be true, it probably isn't. if you punt on the extended bass aspect of things though, things become pretty easy. Low bass is where all the hard work happens ie large efficient drivers and or smaller drivers and more power/current to move them. Its basically the limitations of physics that cannot be undone even with the best and highest quality designs.

Cronus Magnum is respectable with most speakers I have heard it with. Use a powered sub or two with it (or most any tube amp) and cross it over properly and you are golden.
