Speaker recommendation for a Fisher 500-c

I own a Fisher 500C it needs work and is on the "to do" list. It's not the most powerful thing or most accurate out there perhaps has 30W. I love how they look, simply beautiful.
Dynaco A25's would be a good match for the Fisher. The A-25 would need the caps and tweeter replaced for best sound. All in for under $400.00 easy!
We have a rebuilt pair of A-25's in the living room with McIntosh MX110Z and MC2505 great vintage sound.

I have just the loudspeaker for you and it's a boatload less than your $2500 budget.  I've got a buddy who runs a vintage pair of KEF Calinda loudspeakers that he drives with a Marantz 8B power amp.   This is one of the most pleasurable and thoroughly enjoyable audio systems I've ever heard, at any price.  Really.

Your 500C is about 25 wpc and the Marantz 8B is 35 wpc, so they're in a similar power range and I feel would be a good match for the KEF Calinda.   The Calinda and the Cantata were KEF's big loudspeakers back around 1980.  

Being as old as they are, they're difficult to find, but when you do, they'll be priced at $500/pair or less.  If you persist and are resourceful, you'll find a pair in a few months time.  You'll probably have to spend some money on shipping as well, but given your budget, this is something you'll readily afford.  You will NOT be sorry.  Truly wonderful!

As I write this, there's a pair of KEF Cantata's in Monterey, California.  He's asking $450.  This is the sound that established KEF as a hi-end manufacturer of loudspeakers.  You won't be sorry.

I had a Fisher 500C that I got at a yard sale for $1 modded by BWS Consulting of Arlington Va with Bendix Aircraft output tubes and robust power supply. I got a deal from someone who was closing his store on a new pair of Fulton Nuance three-way speakers. This turned out to be a very good combination. I also was using TG Audio cabling and power cords which didn’t hurt. The Fultons are more extended on both ends and much more dynamic than my previous speakers which were naked '57 Quads.
