I also really like the ProAcs. (It was probably because of sbrownnw's recommendations that I auditioned them in the first place--so thanks!) I listened to the 148s with The Pixies, Stone Roses, Nick Cave & REM among others; I can attest they handle pop/rock really well. The difference between a good & bad recording was immediately obvious, but manifested as 2d vs 3d imaging rather than any sort of harshness. I also had some Aphex Twin and the bass is extended and articulate. They do have what I'd consider a British mid-range, but I think that's a good thing when complemented by their excellent treble & bass.
I currently have Monitor Audio (Silver 2) & my guess is MA is not what you're looking for. I find them admirably neutral (especially for the price), but so refined they're almost stodgy--though a power amp of your caliber may be able to kick them into gear. Personally I think the Dynaudio & Vandersteens I've heard are better speakers for rock.
If you don't hear something you fall in love with locally, I'd think setting aside some funds for a trip to a show or dealer or even return shipping would be a better use of funds than buying something non-refundable based on hearsay.
