Hi
Been busy w/work (yes, that 4 letter word) and have not been real current here...
I'm interested in getting a different/better sound than my M10a's. I've moved them all over the room, they are now 3 ft off the ground and better...
What would be an upgrade to these ?
I've seen RTA15's advertised...
I've read some think that anything higher than 11 might have a muddy sound...
