On order, new receiver

The 720 is worth it even for 5.1. The larger power supply give you more watts / channel, especially if you don't use a couple of them. :)

Dweller,
The lexicon is a preamp. I don't need extra amp channels.  I have a bat vk 200 2ch and a b&k 3 ch amp. I will only be using 9 channels.

Eric did u already get this receiver?

Well I did get my new receiver, mrx 720. Spent Saturday hooking up and doing cable management.  Listened to some music and movies.  Overall happy with sound. Tried to do ARC with my Samsung s9,  but microphone is not recognized with phone. Tried ARC again with apple x10 but only the front and center worked, rear kept saying excessive noise, which I know there is no excessive noise because I am the only one home. I have an apple computer, but that software is not available until April.  I have an old lap top I haven't used in a couple of years,  I will try that this weekend. Overall no complaints.  So right now no ARC in use. I set distances and that's all. Sounds much nicer than my old lexicon dc1. Movies the dialog is crystal clear.  I am sure the arc setup will be much nicer. Music sounds great, but nothing to a/b it with.  Using a transparent digital coaxial for blue sound, waiting on a nordost silver shadow, see what that will do. That's it for now. I will update once I get arc working. Pete
