coops, you're very wrong on this one. I don't doubt that you didn't like what you heard when you went to your Cornflake Shop audition. But I had some ATC 50 actives at home for a couple of months and can confirm that they are excellent speakers. Maybe not your cup of tea, but still excellent speakers. If you want hear a piano the way it was recorded (which is NOT the same as saying it will sound like one played in your room, but that's another subject) there are few designs which are substantially better. And most of those cost a whole lot more.
ATC also operate on very sensible margins, Mr Woodman does not drive a Ferrari or anything. Keep in mind that they are entirely made in the UK, mostly by hand. They are pretty good value for money.
