Very Early Impressions:
1. Best Binding Posts I have had the pleasure of working with.
2. Really Incredibly Heavy.
3. Quite a bit better sound quality than the RR2150 for 2 channel when using the RR2150 as a pre and the 7900 as the external amp. This is driving some Tyler Acoustic Linbrook Signature speakers. Sounded *very* good.
No big HT test yet, sorry. When I get the chance I will post that.
