Hey Brother DB94,
Oh yeah, the 3000 is a beautiful piece of gear. However, being the Senior Level EE that I am, I always study Schematics, PC Board Layout and overall construction of expensive gear prior to purchase. I bought the service manuals ahead of time from Yamaha to do so. I could have afforded the A-S3000, but could not justify it technically or sonically. So, I made a judgment call and bought the A-S2100. I have a friend at Crutchfield, so when brand new ones for both of my integrated amps ended up as special purchase, he hooked me up with kick ass deals. In ~ May of 2015 I got the A-S2100 new for $2499.00. In ~ May of 2014 I got the A-S2000 new for $1399.00. I've been happy with my decisions as I re-pieced together my current 2 CH system using vintage stuff I had and adding the newer stuff along the way.
