I've got a Technics SU-R1000 which I think is pretty brilliant and is the first "digital" amp that I have really liked. I also had its baby brother in to play with for a couple of weeks and thought that was excellent as well. I had a NAD M33 for about three months and couldn't get rid of that fast enough.
It's tough to compare the Technics to some of the others because of all the additional features that it brings to the table, so not really apples to apples. There is a gentleman in the area who has the AGD monoblocks and I would love to spend a day with him comparing the Technics and the AGD. I may see if my dealer is willing to loan me his AGDs for a long weekend as well.
I'd also be interested in comparing the Peachtree with the Technics G700M2 as they seem in the same price ballpark. Sorry I can't offer more, I just have not heard any of these in the same room with the same equipment.
