Was the D-Premier upgrade a waste of money?

I think expectation bias plays a huge part, both ways. Without a doubt, it does for me. As is the case, I suspect, with just about all listeners and with just about all quality electronic audio equipment.

And, in my opinion, it goes hand in hand with why reviewers never submit themselves to robust blind tests (recognising as I do the imperfections of that process).

These things gladly keep much of the industry in place, and therefore lots of choice of big boys toys for us all.

I find the corollary of what you are saying rather depressing. It suggests we can't trust our own senses let alone the judgement of others.

Black/blue vs white/gold was a salutory reminder of that, if one were needed!
