Good questions, Tomcy6. I'd also want to know how long people listened, whether they took breaks, whether the units were warmed up equally, etc. FWIW, I don't compare components over what I'm assuming was a relatively short period of time, however. I listen for days (or longer) before switching to an alternative for days (or longer). I have found making judgments based on relatively short listening sessions can be confusing, and prone to erroneous conclusions.
In any case, I'm still interested in the comparisions of the two different modifications stated in my original post. I've gotten feedback from "seasoned" audiophiles I trust about the modded 95s (although no one so far had done a specific comparison of Exemplar and Modwright). Everyone has been very happy (and some raved) about how much better the modded units sounded. I also have owned two modded Denons in the past. Those experiences made it obvious to me that mods can improve these less expensive units dramatically.
