I am not an audiophile but (for a very weird reason) I recently received two pretty high end systems, a couple of 70s Electrovoice interface 1 speakers coupled with a just as old pioneer SA-7800 AMP while the other system is pair of KEF ls50 wireless II. I'd like to know if between the two setups there is a clear winner since I can only fit one pair in my room, what do you think?
