To me this is funny because it is choosing to accept and repeat a subjective review because it fits with the desired outcome. Where is the call for a double blind test?
Anybody that would say they prefer the other equipment based only on sighted listening would be dismissed and told to do a double blind test.
Accepting expectation bias in one direction is not very scientific.
What are you talking about? By mentioning some trends I see on a traditional audiophile forum I'm only reporting we I see. I'm not justifying what members say there one way or the other. In this case going on about double blind testing strikes me as gratuitous.
Members' impressions are what they are. IMO, if it's reasonable to assume anything, it would be a long-term expectation bias against class D amps and solid-state amps in general; that was the case for the 20+ years I've visited the place.
