Thanks Nic, lets wait until I receive my 568.2mm.

I goes like this. My system has been unplugged, an all cables removed for a few years. We have had our house gutted for remodel. Years ago there was a Meridian dealer in Albuquerque who I bought my DSP mini theater from but has since gone out of business . To be honest they tried, their best to start a high end audio store but failed. They never had both subs working when they installed my system so maybe that adds to why they are no more.

Regardless, we are now finally starting the entertainment room so I took out all my Meridian gear and for a novice it is a bit intimidating. I read a lot here and got motivated to make it all work correctly. Run cables in walls and lay some PVC in the slab to hide a lot of cables and put all the gear in a ventilated closet.

I bought (it's on the way) a 568.2mm as this seemed like a upward move and decent first step from my 568. So it's a waste of time to do anything with my old 568 right now as I will first need to upgrade firmware on the new 568.2mm before config the unit anyway.

One question is, althought I have a copy of the 2.5 upgrade, the Meridian site only lists the 1.0 firmware. I think the 2.5 was a beta. Anyone have any issues with it? Any regrets from updating? Why does Meridian not say it's the most current. I would hate to run the update and have issues . Attempting to go backward to an older firmware I have not read about here. I hope the unit comes with the original software in case I need to go back to it.

G61R, HD621, 3xDSP33 (front, center left), 2xD1500 subs, 2xDSP420 (rears), Sonos everywhere.
