Had my Yamy 3 years now but was wondering if its worth upgrading. The 3090 first came out in 1996 when Laserdisc was still king, but now DVD has taken over I was wondering if my Poineer 737 would sound better on a new amp. Just comparing the two, Laserdisc and Dvd, Laserdisc still sounds better on this amp. Why? Is it because the compresion on Laserdisc soundtrakes are less than that on Dvd? Two new Yamys have been released since the 3090. Has anyone else made this upgrade and was it worth it? ------------------ Is he the one?
