Was at Steve's old house, way back in the day when the Zen amp was still in the first 100 serial numbers.  I threw on a Van Halen album, Fair Warning, kind of as a joke, just because I loved the album and I wondered what an "audiophile system" would do with a brash, raw rock album.

I was simply floored by how holographic this album was. You could practically hear the different tracks on the magnetic master tape taking up space in the room. Then when the chorus of Mean Streets came on, you could literally hear all four guys lean into the microphone and belt out the chorus, then lean back. You could *hear* them lean in and belt it out! You could, in your minds eye, see all four crowded around a single microphone...

Then I went on to play some Satriani - Not of this Earth and Steve was like "hey, this is well recorded"
