@ehoeft & Blackdevil77: Thanks for the hint, after an hour of reading in this thread on Mark's forum I'm pretty confident about the Cats. I can agree to the evaluation about the Genelecs being extremely detailed and in some ways "brutally" honest in their sound. To be honest, I can't really understand why Genes are so popular as home theater speakers in the US. I personally don't like them for music at all and I doubt this would be different when watching movies. To my ears they sound sterile and extremely analytic, without any emotion, harsh in the highs and mids and as said in this thread very fatiguing. If Cats don't sound this way, a bit less detailed and more warm and full of dynamics, they are in my opinion much more suitable for simply enjoying music or movies, while the Genelecs are rather a workhorse developed to dissect sounds in a studio.
@zamboniman: Thanks a lot for your comment. You are stating what I already supposed. Given these specs on paper, Cats must be incredibly powerful speakers with tons of dynamics and headroom. To put that clear: SPL is not a mean category for me to decide on a speaker. Distortion, transparency, dynamics and precision are much more important for me. I just want to make shure, that these speakers are able to outperform my current monitors in almost every aspect, for this would be my goal in a purchase of this dimension: To buy the last speakers of my life (and this does not mean, I'm gonna die next year
) and, as you mentioned, "cure my upgradeitis". The categories mentioned are the ones where my Opals rule. SPL is just a nice side effect of a high powered active speaker which only gets interesting when it comes to the rare opportunities, when I use them for smaller parties at my place. I intend to use them in a couple of different occasions, such as music listening, movie watching and celebrating partys. They should be suitabel for every kind of use, and I'm meanwhile pretty shure that Cats are.
