I’ve finally had a chance to really listen to my new amp and I have to say it’s impressive. I’m listening to Jackson Browne, “ the Pretender”, at pretty high volume and I’ve never heard my Aerial 7t’s scound like this. The bass notes, the drum strikes are just amazing, the presence of the music in the room is incredible. My Vincent amp sounded pretty good but this is just another level. Using my Vincent as a pre amp, the 452 just seems to make the music come alive.
