Amp Recomendation - Aguilar DB751 but smaller?

I love the Aguilar DB751 I bought a few years ago. It is so clear, articulate, fast, and punchy. It is also phenomenally loud. Much louder that I need.
I'd really like the exact same performance and EQ in a smaller package, but I don't know if that exists. When I try to go back to a Mesa D800+ I can't find the tone or the assertiveness my DB751 has with it.
Any suggestions?
 
If you like the heft and the slam of the DB751, you still need to wait for a light head.
IMO, none of them match the DB.
The light heads have come closer and go loud, but none of them match the slam of the DB751.
The light heads low end sounds castrated by comparison. IMO
The closest light heads that I have found, so far, are the Aguilar AG700, Eich T-900, GK MB800 fusion, and the GR Bass ONE 800.
For medium weight, the Mesa M6 at 26 lbs was respectably close.
I've been trying to find a light DB751 for over 7 years.
After you have a DB751 and it is the sound that you like, it is difficult to find anything like it in a light package.

You feel that there is something particularly unique about the build of the DB751 that gives it a tone that can't be reproduced by a class D? It isn't just the EQ?
 
Call me crazy, but all of the light heads that I have tried, do not go as deep as the older heads. They will push bass, but not the real deep bass that you normally hear through an audio subwoofer.

Whether that is from damping, transformer, mosfets, HPF cutoff set at 30 hz vs. 25 or 20 hz, something else, or a combination, I don't know.

To my surprise, many bassists don't care for the heft and use HPF filters set between 50-100 hz to remove it.
IDK, why play bass if you are going to remove the best part? I am in the minority though.
Not all cabinets can produce the depth properly either, which may be why some cut those frequencies.

Some bassists prefer a "piercing" bass vs. a full bass too.
 
Agree with @J.Wolf, the Arkham BOBW utilizes a James tone stack and can be dialed in nicely. I use Arkham preamps and love them. If you don’t mind a power amp/pre combo, the old Demeter VTBP-201 is very clean, punchy and stays that way at all volume levels.

IMHO the sound and feel is more related to designer intent than anything else. IMHO, my 30W Ashdown LB30 Mk2 has huge lows and massive slam, so huge power reserves are not necessarily a requirement.

I think the contour of the frequency response and how the amp reacts and recovers when dealing with transients are the primary factors. How the amp reacts and recovers is essentially the shape of the compression envelope. One other factor is damping...I.E. how tightly the amp's output section controls speaker excursion. Tube amps tend to have lower damping than solid state, but the designer has some control over this factor.
