What do you consider the most musical speakers—$15000 & under

Hard core hobbyists know that the term "musical" is code for mushy, indistinct and bloated. The term "accurate" is code for brittle, dry and clinical. 

What you really want is a speaker that is neither musical, nor accurate. ;) 

helomech, the performance range of audio systems is FAR greater than many realize. Experience in the home is often the only thing that can change that perception. The change which caused your  jaw to fail is a small part of a broad spectrum of performance change possible in the realm of systems.  :) 

I owned the 1B and 2CE in the past, and there is a nice bump in performance in the 2. Don't worry that you wouldn't hear a significant difference. 

The 7's are quite nice, but imo not inherently superior to many other super-speakers. YMMV 

You may wish to hang on to the Spendor speakers for a while, and conduct comparisons as time goes on. That would be informative. 

helomech, I did that very thing; moved from the 1B to the 2CE and it was in a compromised setting where there was an entertainment unit up close between the speakers and they sat about 1 foot from the wall. I put some sound absorption behind them. Great upgrade, never regretted it. Would do it again if in similar conditions. :)
