Chat, A-S class D and Klipsch

Room is 26 x 14 x 9, 16 panels on walls, 12 panels on ceiling, 70's rock is my main listening, little bit of jazz. 99% digital these days.

currently have revel f208 and svs subs, I like the sound but I would describe it as very neutral.

it sounds stupid to say but I'm looking for something more "musical" or engaging. 

I found it interesting that AI suggested speakers I would more associate with tube amps or low watt class A's than the D's 

Using Luxman 590AXII (30 wpc class A); plenty of power and sounds great with Forte IV's.

If you have the extra dough, I would go for the Klipsch Cornwall IV.  Much better bass, and a much fuller sound.  If I wasn’t already committed to my JBL’s, that is what I would go with. They are extremely efficient and will go with any amp. 

I agree and think a horn/folded horn speaker or single driver speaker might do the trick. I have Charney Audio Companions (with the AER BD3s) and also own A-S Class D amps. My system is very musical while still revealing details. No fatigue whatsoever on long listening sessions. I also pair these with SVS subs. I have not listened to the A-S Ds with Klipsch, but also previously owned Rethm speakers which had very similar attributes to the Charney's. These high efficiency speakers really show the magic of the AS mono amps.

The speakers you (AI) mention have a fairly dramatic price point difference. It may be helpful to know what your price point is. I don't know where you are located, but you are welcome to have a listen here (New Orleans) and Charney Audio is located in NJ and would definitely be worth a stop.
