D’Agostino Integrateds

@maxwave Sorry if my thoughts wasted your time.

@creditingkarma You are right.  The YB MK2's don't require 400w mono blocks.  I bought the amps as part of a plan to do a significant remodel that would have given me a much larger listening room and an opportunity to try bigger speakers.  For reasons not related to audio those plans changed.

My current listening room is small.  It's kind of an L shape, 12 x 16, widening to 15 in the rear.  The shape is the result of a bathroom and two doors.  The room is below grade and very solid so the sound right now is great.  It's a very quiet room, <30Db background.  The Estelon's image really well though they are short on deep bass.

So yes, I originally planned to move to bigger speakers.  Plans changed and everything sounds so good right now I'm reluctant to change.  I finally have a turntable with two tonearms and I'm enjoying experiencing different cartridges.

I was asking a question about Amp/speaker  possible integration.

My complete set up : 2 Channels  and  Home Theater is over 200K $ 

And I have plenty of time  😉

@g9taylor I understand on the room size. I went from Atria II to Cygnus. I loved the Cygnus but had an issue with the pair that I got and decided to go with Estelon. My room is 15 X 17.  The XB diamond play really well n the room and are not bass light. They are not flat down to 20 but they play well below 30hz with great authority.

Classy , elegant . Not  ostentatious .  The magic is rather inside

The remote is like a small computer . Always commicating with the grears .

Speakers like the Atrias are relatively tough impedance loads. As such, when paired with most tube amps, there is a mid-bass boost, hence the warmth. Actually, tube amps create this effect with the vast majority of speakers (why peeps claim tube watts sound more powerful), even many high sensitivity speakers if they don’t have a mostly resistive load.
 

You are probably experiencing a much more linear response with the D’Agostino. If you don’t have the luxury of experimenting with speaker placement, you can try reversing the speaker cable polarity. That may cause a bass boost or null depending on your room acoustics and the amp’s output polarity. Otherwise, if you haven’t had the amp for long, you might do well to give your ears more time to adjust to the new sound.

Chances are that upgrading to a “better” D’Agostino amp will not provide the missing “warmth.” Maybe consider a Sim Audio or Boulder integrated.
