> How high would you have to go to better the performance of the cosmos?
An unanswerable question, one calling for an informed and critical opinion of one who has not only heard the Cosmos at length but who has extensive experience with, say, Rockports, Caliburns, TW Acustic, etc., etc. I would speculate that those folks are few and far between - and then there's the issue of listening biases to take into account.
I'll stick my neck out and say this. I think that it's unlikely that my Cosmos - with Triplanar arm and (currently) ZYX Universe - is unlikely to suffer in any comparison that could be devised. I have no doubt that better exists, but how much better? I personally feel that I'm at the cliched 'law of diminishing returns'. Of course, others will argue that this point occurs with the (excellent) Rega P5, for example...or does not occur until you hit Walker territory.
