While the stock caps supplied with the std Pi and Bottlehead stuff are fine, when you have very high quality drivers and/or finicky ears, then upgrading the caps can make quite a difference, especially in the trebles you're discussing. I suspect this is a large part of what you're trying to achieve. I noticed large difference in my Bottlehead stuff with better caps, and I'm using P4's with JBL woofer and B&C DE250. I also used Auricaps in my xovers, except for the big one, I used an Obligato film that sounds very good and was much cheaper. When I just replaced one small Auricap in the high-freq compensation part of the xover, the highs smoothed out (to my ears) quite a bit.
I have a soviet teflon as coupling cap in Seduction, with an Auricap output cap, and all Auricaps in the Foreplay and Paramours. Others like different caps better, but the Auricaps are a safe buy. The Paramours also improve substantially with the better output xfmr, most notably in the quality of the bass. I think your speakers may be revealing some of the other limits in your gear and may not be all room issues. Most of these changes in the Bottlehead gear are quite ez to do and give a large bang for the buck. As with all this, it's subjective, but you're way up on the speaker food chain, and could upgrade some other parts to get all the benefits.
