It's been a full two month wait and I've only got about an hour of playing time on it so far, but here's a short initial report. The amp arrived very well-packed, but this turned out to be no defense from the shipping company. This is a heavy brute that apparently took a shortcut or two along the way. There was something rattling around inside and it turned out that one of the 6550s had broken clean off. Man is this thing OVERBUILT! Anyhow, it took a while to extricate a few errant bits (thankfully only plastic and glass), finally get a new tube in there and tentatively flip the power and standby to the "operate" position. Good to go! One of the reasons that I had thought to buy this amp "new" was the excellent warranty, handled through my local dealer. One way or another they're going to replace all of the tubes (so that all are properly matched), but in the meanwhile I am fully operational. There's something to be said for that little bit of insurance. Now to drive home, trying not to get a speeding ticket along the way. To say that I wasn't prepared for this amp is an understatement. The sound is HUGE!!! To be honest, I'm not sure what I expected. I was hoping for something comparable to my Trace V8, but this is a whole new level. There's more than enough power to drive a pair of Acme Low B2s, and at levels seemingly comparable to my PLX3002. Of course there is a little less headroom, but digging in yields that trademarked Aguilar tube-y goodness. To my ears the sound is closest to a vintage SVT than anything more modern that I've heard, it's just that there's a bit more of it. Hey PBG, what are your thoughts? I know that you recently started playing with one of these. Comments welcome. I'll follow on with a full report in short order.
