I've got a pair of the PSB Gold i and think that the tweeter sounds pretty natural. It took me a while to get used to them after being used to Infinity emit tweeters. I admit that sometimes I think something sharply defined like the Nautilus 805 might be nice, but that's a different kind of sound. What kind of sound are you looking for?
I found that bi-wiring with a fast cable like Nordost and a source with clear highs like SACD can make the Gold's tweeters sound pretty good. The guy (Paul) who developed the Golds spent a fair amount of listening time when developing them, but I suppose this audio hobby is about getting out that last bit of performance if possible.
I'd like to hear how your changes turn out.
