I have a Denon Home theater amp with BNC capability, or I could go direct to the plasma with DVI. Is there a big difference in quality? (Source signal(s) being PC, DVD, and cable)
It would be more convenient to go through the amp as I would have a single point of consolidation and control.
In theory since DVI is digital and BNC (component) is analog, DVI is best. But in practice, you may not be able to tell the difference depending on the incoming signal, the specific equipment used and your eyes.
