Looking for Speaker Recommendations - Halo P3/A21

Hi,

I've been upgrading my system lately and was wondering what the group would recommend for speakers. There are two primary goals to my speaker upgrade.
1. Not feel the need to change or upgrade anything in the system for several years.
2. Have a reasonable WAF.

My system was Adcom 555 and GTP-500 for amp and preamp along with Arcam Alpha 7 CD player and Castle Harlech speakers for the last 15 years. I recently changed out the amp and preamp with Parasound P3 and A21. Have settled on an Oppo BDP-95 to update the CD player which will be purchased very soon. I feel these three items will be a huge upgrade/improvement over what I was running. So at this point I see the speakers as the weak point in the system.

The Harlechs have been a very good balance for this system in terms of price and sound and appearance. We don't have much room for speakers so a tower arrangement like the Harlechs would probably be best.

I see a lot of recommendations for Thiel and Von Schweikert that look like they would fit in my budget but don't know if they would be a good fit for the Halo electronics. Some of the B&W Nautilus models fit my budget and appearance requirements but I hear they are somewhat bright.

I listen to CD's exclusively and lean to pop, rock, and R&B selections mostly.

I have a budget up to $3000 but I see where a $5000 budget might get me a pair of Wilson Audio speakers and wonder if those would be appropriate for my system and keep me happy for a long long time to come.

Any and all input is welcome.
