Salami have you listened to any jazz piano or solo piano. The piano is what first blew me away. I am not sure but I think the horn driver and the mid/woofers are time aligned. I think that is why some recordings sound very good and others show some flaws.

We are discussing HF drivers on another forum regarding rather ferrofluid damping is a good thing. I also have a pair of Focal speakers that do not use ferrofluid in the tweeters. I do not know if the horn tweeter uses any and if not that may explain it's speed and detail. The Studio 5 series are amazing for the money.
