A surround sound processor is the sum of all individual parts. Thus quality of both analog and digital sections play a pivotal role in sound.

How does a Proceed AVP Dolby Digital surround processor compare to a middle of the road Dolby TrueHD setup? Am I better off using the 5.1 TrueHD analog bypass or letting the AVP decode AC-3 surround material?

In it's day, the Proceed AVP sold for close to $5000 and featured balanced analog section (Left,center,right channels) and discrete d/a converters for surrround channels. The analog section still beats the pants off any mass market Japanese gear.

I'm wondering if uncompressed 24bit/96hz Dolby True HD will beat 10 year old AC-3? Should I feed the analog 5.1 Dolby TrueHD from a Blu-Ray player through the analog bypass?

Moving from Dolby Pro-Logic to Dolby Digital AC-3 was a quantum leap back in 1997. I don't expect Dolby TrueHD to be more evolutionary rather than revolutionary.

Can someone here please provide anecdotal evidence supporting the difference between Dolby Digital and Dolby TrueHD? Thanks!
