Unpacked.

On first listen, the ADS L620s are very precise and neutral, with a great tweeter (writing as I'm listening). They are much bigger than I'd thought they'd be (I guessed the Altec 3s would be the larger boxes) and more authoritative, this after 3 Art Pepper songs (Art Pepper Meets The Rhythm Section).
This is big fun!
Yes that's a new Marantz in the corner of the shot ( not too soon- both the 1150 and 1070 integrated amps are gone).
