I have the passive and I am soon going to be running it with Benchmark AHB2 amp ($3k) + Benchmark DAC2 HGC ($2k) which will be replacing a breaking down Parasound A23 amp. I would recommend you get the ACTIVE version from Amazon or KEF Direct web store. Since the performance is very high with the ACTVIE and you would likely need to spend a lot of $$ like me to equal or better the ACTIVES.

I likely will get one of the following integrated amps (including DAC) to drive the passive LS50’s when I move the LS50’s to a bedroom from the office (likely next year).
NAD C368 ($800 - $1200 with ROON Ratt module)
Rotel A14 ($1299)
Hegel Rost ($3000 Apple support)
Peachtree Nova 1500 ($1700)
I will get something bigger for the office where the LS50 currently reside. Thinking of getting something like the Magico S1 mkII or S3 mkII or the new Yamaha NS 5000 for the office.
