Well okay, I guess I was a bit brash...
This is where I come from. My high-end journey started out with QUAD 57 ESL speakers (no-brainer!) but I had to let them go as they too up too much space.
Roxy, I should have included the next few lines: Please note that I use the word "conventional". My B&W P6 speakers had the most lovely tweeters; io, they disappeared in the sound-scape. They were most certainly not conventional. Metal alloy dome, very powerful magnet, small baffle space and good weight behind them (well coupled).
The QUAD 21L speakers have "conventional" tweeters and they draw too much attention to themselves.
Spendor S9e speakers have bloody fine tweeters.
B&W 704 have sexy tweeters.
Sonus Faber Cremonas have elegant tweeters.
Yeah... I am p!ssed. Pardon that. I just cant stand a bad tweeter. My quest continues for better speakers.
