Tube Amps With Good Bass Qualities

While the Atmasphere OTL Amps with the right speakers trump almost everything out there, I recently have been subjectively amazed by the VTA ST70 I put together, in terms of soul massaging bass, for a small fraction of the above price.

Thanx Ralph,
I think you just want them to recommend your amps:)))
I hear you about the financial aspects of the audio business. Not any different from any other consumer oriented activity. I include medicine in that category.
Atma-Sphere amps are expensive because a human has to sit at a bench with 13 rolls of colored wire and a soldering iron hooking up one wire at a time on an awful number of tube sockets. There are no circuit boards, another profit increasing approach. I would rather support an American worker than a Taiwanese robot. There are many solid state amps of similar power that cost a lot more although the MA-3 is seriously up there. (twice as many tube sockets)  

@mijosyn,
From what I read, I did not find Ralph extolling his amps, but only providing an overview about what happens and why.

Even with the smiley emoji, I think it not fair. 
Especially so when there are other dealers on Audiogon who would be much more blatant.
My 2+ cents...

Bob, the smiley face was to indicate that I was kidding. I was simply responding to his comment about not wanting to mention other manufacturers who he seemed to think were inadequate to some degree. Ralph does not need to make any enemy's in this business and remaining politically appropriate is important especially where humans are concerned. IMHO they are vicious animals. Lighten up!

+1 On Primaluna Especially the HP (they also have a sub out tap)

Found Atmosphere's response fascinating. 

If I understand correctly that you have Klipsch Heresy’s w/ a frequency response of 58-20,000 Hz..then a sub couldn't hurt. 

I run a small sub (many to find used) and wow. With a PL too under 5K.
