With levels matched, the same tracks hit much lower instantaneous peak levels, even though average levels are exactly the same. Switching back and forth between the 1502 and an MC275 feels smaller, significantly smaller, and the MC275 is no slouch. Even with somewhat compressed Motown tracks, Diana Ross’ lead vocal in “Standing at the Crossroads” Jumps up 20db with ease. Meanwhile the softest parts of this track fall all the way down to 55 db, with the room going “silent” at 29db. Listening to The System’s hit, “Don’t Disturb This Groove” at a modest level of about 82 db, I’m surprised to see that the sound level app on my phone is recording 112 db peaks. And in this case the new MC1502 delivers incredible dynamic range. ![]() Much as I like small Class A solid-state amplifiers, SET tube amplifiers, and small tube amplifiers like the hallowed MC30 amplifiers from McIntosh – there’s no substitute for power. ![]() Much as I like to dismiss measurements when it comes to the subject of hifi, there’s one that I find intriguing – sound pressure level, which relates closely to dynamics.
