Kharma, Wilson Sophia, JM Labs I'm confussed????

I too think you have a nice system. Given your room size, I'd be careful about going with a large full-range speaker, it could overload the room in the bass and you'd lose the flexiblity you have with the separate sub to control the deep bass level; if you like the JM Labs speakers you have, the next size up might be a good choice, but make sure it works in your room.

I'm not sure what you mean when you say the REL doesn't have the full range sound. Where (at what frequency) do you cross over to the subwoofer now--perhaps lowering that crossover point will help?

I think a used Kharma 2.0 or 2.1 would work nicely. Easy load,good bass,exceptional mids and highs and will work great in a medium size room.

I have put in dedicated 20 amp lines to the room. I also run everything through a PS audio power plant. The room has had extra insulation, and I'm having my audio guy tune it a little more. The truth is I'm greedy. The set up sounds fantastic today. I just love the full sound of the larger speakers, but the speed and clarity of the Micros may be hard to beat. When I said the full sound I was referring to the total set up and not the REL. The REL does a great job of filling in the bottom range. I just heard the new Divas. To be honest I like the micros with the sub better. Don't we all want everything??

The AG horns come with subwoofers (must get the newer CTRL 225 subs) with controls for bass volume and roll off frequency. In your room, the Unos would be great (do not be tempted to go for the bigger horns [Duos or Trios] in your room - it's too small). Set them up well and they'll fill your room with music.

FWIW I just went through much of the same thing. I was looking at a little different group of speakers, but I bought a pair of Kharma Ceramique 1.0 from a gentleman here on AudiogoN. I narrowed my choices from the Wilson Watt/Puppies, Sony SS M9ED, and B&W Signature 30's. After my looking and studying, I have yet to hear anyone say the Kharma's were not a great speaker, while listeners are more divided about the others.

Good luck!
