Sorry Syntax, not sure I pick up on your drift. Do you concur with Djcxxx and me, or do you have a different view.
Btw, I left my PH-8 on all night and listened the next day. No question now about warm-up. Here's my updated reaction. I think the PH-8 might (??) have a lower sound floor than the PH-7. As a result, I think my vinyl playback has less hiss and noise. Does this relate to the PH-8 or wishful hearing, I don't know. Nevertheless, overall, I still think the PH-7 and PH-8 are cut from the same sonic cloth. And I am not convinced yet that the PH-8 is worth twice the price of a mint used PH-7.
Btw, btw, I called ARC to see if there's something else going on that needs a tweak, or if I need the services of an audiologist. Should hear back next week. If I learn anything worth passing along, I'll share.
