You explained it yourself why Soundlabs don't get much attention. They need 600 SS or ,I assume, about the same tube watts to sound their best. That's what? $30k or so? Or more? Few want and can afford this set up.
What does one purchase after owning horns?
I have owned Avantgarde Uno's and sold them because of the lack of bass to horn integration. I loved the dynamics, the midrange and highs. Now faced with a new speaker purchase, I demo speakers and they sound lifeless and contrived. The drama and beauty of live music and even the sound of percussion insturments like a piano are not at all convincing. I have an $8k budget for speakers give or take a thousand. My room is 13'X26' firing down the length. Any good ideas will be appreciated. My music prefrences are jazz/jazz vocalist.
