Tube Integrated with deep bass

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.

My 2c.

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.

I agree with Plato,this amp digs deep and is a tube rollers dream,no fuss ,just plug in play.Hard to beat for the money and sounds fantastic on klipsch speakers or any speakers that you do not need a ton of power.It's a no brainer........if you need more bass, get a sub..
