One thing that ought to be mentioned is to be careful the burn-in status of speakers if you get a chance to audition before buying. I recently purchased a pair of KEF LS50 Meta loudspeakers, which people say needs at least 100 hours of burn-in. I ran them 24 hours a day for a week straight and the sound barely improved. It took more like 500 hours of burn-in and now they sound absolutely night and day compared to new or even with 100 hours burn-in. Auditioning speakers that still smell like the packing container won’t give you a proper impression of what you’re getting!
