On digital amps: they have to convert back to analog at some point, unless our brains are going to be modified. We don't listen digitally. And pushing the digital compromise further down the chain doesn't improve things. I listen to some of the best digital front ends on the market every day, and they still suffer a 4-8:1 cost disadvantage compared to analog, and never actually catch up.

A large chunk of higher resolution material (35mm film) has a huge advantage over a sensor 2/3 the size with lower resolution. If you want smoothly graduated grainless tonality, film is still IT. Full sized sensors get you closer. Medium or large format digital backs get you closer still, but now we're up to the price of a subcompact car.

Digital sources and cameras win on convenience and ubiquity. I use my digicam for product shots for the web and trade show coverage. I use film for personal satisfaction. The digits still lose out on quality. IMHO. YMMV.
