I've a DVD player at home that I use primarily to watch Concert DVDs, I have a good collection of titles. The setup is as follows: the signal goes to my TV (both audio and video) and there's also a digital output that I send directly to my hi-fi stereo. When I watch a DVD I silence the TV and enjoy hi quality sound through my chain. I was wondering what would be the benefit to switch to a BlueRay platform and what I could "gain" in terms of experience as I watch concert on Blue Ray. Any significant pro?
