Tube Integrated with deep bass

I don't know which speakers you have but if you want an integrated amp that has the qualities of tubes but a solid state output check out the Pathos. You will have the tight bass you want and an excellent midrange and top end. Deep bass to me is a coloration. A good amplifer should deliver the quality of the recording and the essence of the recording. It should be neutral. From what I have heard the Pathos is a good beginning. Visit your local dealer and give it a listen. I do not own the Pathos yet but it is on my short list when I stop using separates and go to integrated. It's just one of the integrated amps that sounds good period. Don't expect many tube based integrated to have tight bass. Finding a tube amp to go deep with control is the problem. And last how they integrate with your room and speakers is the next problem you have to address.

Ditto the Pathos. Audiomat is a very good all-around tube integrated, but the bass might be what you are looking for, even though the lower mids make up for it.

Deep bass is most a matter of system integration rather than a sonic signature of a specific integrated amp. I own an Audio Note Meishu integrated which integrates in a very favorable way with Avantgarde speakers developing clean and articulate bass response.

Plato,
I own the Dialogue II and even though it's a great amp it does not reach deep down like my previous tube amp. Granted, my previous system was separates. Anyways, I have changed power cords to MAS ( Audioone Reference ) and also BMA Pinnacle Gold ICs and it's getting there, deeper and also more defined. I was wondering if switching tubes to something besides the KT88 is going to help.

KR Audio Kronzilla SXi. Goes down deep and never loses its grip. Not too shabby over the rest of the spectrom as well. Really shines with Duke's Audiokinesis Jazz Modules.
