Mr. Bill,
I found that the LS50 needed more power than I was giving them, especially at low volumes. At the time I was using a Hegel H80 (75WPC), and it sounded a bit like the vocals were being projected at me while everything else was a bit recessed. When I really cranked the volume up, they came to life. However, my listening room is small/medium sized, and I'm in an apartment. Listening at high volumes isn't an option. I think they're exceptional speakers, and the bass was quite remarkable. As I mentioned, vocals were very clear and realistic, and that is something I miss now that I have the Tritons. Paired with a slightly warm, high powered amp, I think the LS50s would be far beyond what you can get anywhere near the price point.
Feel free to ask anything else.
Best, Scott
