I have upgraded my system, a wee little bit.
I purchased a Paradigm Millenia 20 center speaker for the "B" room. I also upgraded the Anthem MRX500 to an Integra 80.2.
I have to say, as good as the MRx500 was, the notice in sound improvement after adding the Millenia 20 and Integra was noticeable.
I also ditched the cable tv feed for a satellite system.
Not wanting to leave the MRX500 lonely and stranded, I bought Paradigm MilleniaOne satelites (2.0), and the MilleniaSub. My thinking was to setup a mini-system in my bedroom. Of course, the DVDO IScan is back in its' box now that I have no use for it. And I had to take the 79Avi out of the rack to make room for the satellite receiver.
Unfortunately, it takes time and thought to plan upgrades properly. As it stands, the following is just sitting in my basement, along with the IScad Duo, waiting for active duty.
I'll update my pictures later, showing the Millenia 20 and Integra 80.2.
