im looking at the denon 4310 ci 130W and it has the Anchor bay chip like the yammy so that is a good thing. see them roughly 1300 after digging some more. its wortht he couple hundred if this things are stable at 4ohm and can run them without an amp and if I need to in the future go with an amp. Im glad I checked on here before pulling the trigger. Now I can wait a couple of weeks before buying the receiver and go ahead and order the speakers as well. I think my ears will be very very happy. I actually have an electronics degree but seldom use it in the IT field or hi quality sound field smile so I like to tweak things and muddle with them. Also the denon 4310 has 6hdmi2out. AWESOME! So m80 and vp180's here I come.
