Upgrade to sound quality of Dynaudio Heritage speakers


Folks,

My current system consists of Ideon EOS DAC/Streamer (I haven't pulled the trigger on their Time re-clocking unit yet), Dynaudio Heritage Special stand speakers, two REL S 510 subs driven with a PASS Labs INT 25.  I'm thinking I can get more out of the Heritages if I upgrade the amp and was looking for some input for a piece of nice gear in the $10K-$12K range that would upgrade the overall sound of my system.  I like to listen to rock/jazz, etc.  My listening room is 15' x 27'. Any thoughts or suggestions?

@jmascian my amp pushes 80 pounds. It sits on a piece of 2” thick sandstone, sitting on the floor, picked up from local purveyor of cut stone to builders and landscapers. 
However that is about to change. 1.5” x 22” x 36” oak butchers blocks with metal legs.

I am fortunate enough to have a real lumber yard not so far away. And they will make up butcher block slabs to order. Oak, Cherry, Hickory, Ash, et al,.

I paid $180 out the door for the aforementioned block, $36 for the 8” legs from Amazon. Finished the block with a Howard’s beeswax/oil product. 
For such a simple thing I’ve managed to over engineer it. C’est la vie.
Food for thought. 

Folks,

It's been while, but I finally hooked up the new Pass Labs INT 250 about a month ago.  Shazaam!  I'm hearing music I never thought possible through my speakers.  The deepest defined bass I've ever heard.  Chris Squire never sounded so good.  The drum sounds as if the speakers are downward ported but they are rear ported.  Great definition. It sounds as if Billy Cobham's kit is center stage.The unit isn't even broken in yet, so I am expecting more surprises.  I think my next move is to treat the room with acoustic panels and sound diffusers.  I am so excited.  Thanks for all your expertise and enthusiasm.  

Congrats on the Pass 250. I’ve had one for a couple of years. I have 5 other intergrated that I rotate, but the pass only gets used  in fall and winter. It heats up my small room to much any other time. I also had a pair of heritage speaker, I believe they were too much for my room. I have used my special 40’s with the pass with much better results.
