I find that an interesting post, especially about the improvement in the dollar to sound ratio. I am playing with a new iPOD, I will buy a Wadia dock, demo or used, in a few months. I am wondering of the existing DAC in the IPOD is likely to be better than the decade old outboard DAC and separate jitter reduction box I already own. It will be interesting to find out.
It also addresses my other issue, misuse of the language. If today's $500 gear outperforms $5K gear of a decade ago, was that gear ever 'moderately priced'?
