I like my KEF LS50 over my previous Revel Salon1 on the higher frequencies (bass was phenomenal on the Salon). So I would choose the KEF over Revel.
I am using a Parasound A23 that I got from eBay for $500 with my KEF LS50 and it WAS a very good match for the price. After about 4 years now this amp is failing on one channel so it is going to be replaced by the Benchmark AHB2 amp. I would recommend the Parasound amps with the KEF LS50 for a relatively low cost solution for very good sound. In fact, KEF use to demo the LS50’s in the USA with the A23. I think they wanted to show that you could get great sound without breaking the bank.
Another option is the ACTIVE KEF LS50. Reviews of this new speaker should be coming out now.
