@glenewdick,
Thanks for the reply. I absolutely believe theres a synergy between ears, mind, listening equipment and environment. It’s not exact because I’m using a dac, but technology have definetly advanced. Unforfunatley as it advances some features sometimes get taken away and we pay a higher price for that same feature down the road. For example, treble and bass control taken away from bottom line boom boxes. My other example is listening to oldies vs newer versions. A comparison between a single tweeter and full range. This may seem off subject, but shows lineage in advancments that could be comparable, at least as it pertains to an ever changing world.
The copper advancements seem worthwhile. Geomtry might have some comparison like a tesla magento in an ideal world. We hopefully see a difference between silver and gold in conductivty. Eddy and grain structure are intersting with noise floor too. And I have heared stories where engineers tweak equipment and songs, which seems like it could make or break.
Thanks again.
