I currently have the setup in my sig and am seriously contemplating a major change. I plan on upgrading my amp to the beast that is known as the AVC-A1XV and starting to replace my speakers with M&K S150's to replace the KEF TDM THX speakers i currently have. Primarily this is because i want to wall mount and i prefer the sound of them. I then want future automations to do a trap door system for my plasma to "minimise the look" of my home system. The reason for the AMP upgrade is more HDMI ports etc. Is this worth doing or should i just stick with what i've got?
