I have been thinking of getting some new powered speakers to replace the old eons I have been using. I haven't been lurking here in a while, but this was the first place to check out for recommendations and reviews. Before I was finished reading this thread I placed an order for one last night. Thanks to all who have participated in this thread, and especially the ones who took the time to write a review.
One other factor in my decision to purchase this amp was Aspen's involvement here. His honesty and his offers of help to people sealed the deal for me (sorry, I don't remember user names, but specifically the one with a Bb hum, and the offer to the person in Sweden).
FYI, Sweetwater called today to inform me it was on backorder, there were several people ahead of my order, but they hoped to have the next shipment by the end of December. I look forward to receiving it.
Again, thanks to all.
