New high end processor

If your not going long distances, like over 10 feet, I would go un balanced RCA type. It will say you some money. Most people say you cant tell the difference on short runs .

By the way, when I contacted Accessories4less and enquired about the warranty on a refurbished 8805 he told me it was a factory warranty. He then told me that I could get a brand new one for $200 more by using code upgrade200. Pretty cool. $3400 delivered.

Luv my ht especially for DVD and blu Ray concerts. Have fun with your new toy.

Take a look at the Monolith HTP1. 

The AVM60 and MRX1120 share the same toroidal power transformer = better noise isolation and power distribution over the MRX720 and MRX520 receivers. The AVM60 has a balanced digital section and is truly balanced across all channels on the output stage. All current MRX Receivers and the AVM60 Processor have HDMI 2.0a 4k HDR w/Dolby Vision. 2.0b gives you eARC (enhanced Audio Return Channel in this case) and whether that actually gets used will remain to be seen with HDMI 2.1 now on the horizon. If you need to decide whether you can’t live without current eARC compatibility, here’s a good article explaining it:

The most complaints we received from Dealers was that we should have priced it at $5000.00 retail instead of $3000.00. :)
It is on sale right now at 20% off till May 31, 2020.

I hope some of this information helps you in your decision making process if you ended up disappointed or decided differently?
Thanks,
