Incorrect. And I am not referring to the specific brands you chose but the theme of presenting a high res powerful SS amp as more resolution than a SET. I have heard a few systems with Boulder 2160 including comparing the amp, and while it is a high resolution amp, the system resolution has always been quite poor compared to good analog playing through a low watt set into highly efficient speakers with simple crossovers. Because the latter is more closer to straight wire as compared to putting loads of junk in the middle of the signal path
Correct. Ron is looking at the preamps in isolation, not in the context of the rest of the system without which the preamps can not make a sound. To take his "non-partisan" certainty of the claim seriously, we need to know the context in which the "observable fact" was "subjectively impressed" upon the listener. And was it presenting pop girl playing guitar on an '80s recording?
