So…a few years ago, long before Verdant, I had a very similar system I chose to upgrade. My speakers were Performa3 M105s. I had a Rogue Hydra power amp with an Ayre preamp. Rega table. I actually auditioned the RP5 and really liked it.
My experience was that for a modest increase in price, I was unable to find a speaker I thought was “better.” I could find ones that were different. Something like MA gold is definitely different but I am not sure if it is better. I waited for the BEs and was not in love with them when I heard them.
Basically, you have a REALLY good sounding system that is well balanced tonally. Each of the speakers above is going to change the sound. Special 40 warmer, B&W will be brighter, etc…. You may or may not like this.
Given that I really loved the Revels, I struggled to find anything I liked better under avoid $6k at the time. This was 5 years ago. With inflation….
I ultimately bought Raidho’s which were a huge departure and a mistake for my room as I lacked the space I needed for them. I ultimately restarted the search. Failed and built my own speakers as they were what I ultimately liked better.
I am 100% sure I can introduce you to speakers you will like better than the Revels but not on an ~$4k budget. By all means search, but hold out till you find what you love.
