Thanks. I have read through this on Cary Direct several times. It isn't terribly thorough.
No, @billpete , the Cary manuals are not well detailed when it comes to tech info, but I am thinking that you will be hard pressed to find much else available. Thanks to @harpo75 on these last few threads, I have learned way more about my '05 than I ever learned from the owner's manual.
I don't see anything in the owners manual that says the function of the 6SN7 slots as to which ones do what.
@harpo75 could probably help you out with that also, or maybe you could find a review online (such as Stereophile) that might talk about that. (They actually did on my '05.)
It does say that the SLP 98 is phase inverted so that speaker wires should be reversed.?????????????????? I have not reversed mine and I certainly do not think that I'm out of phase. Wouldn't I be without bass?
I think that now we are getting into the difference between absolute phase and relative phase which is another (of many) subjects I am terribly bereft of understanding on. Possibly @atmasphere or @harpo75 would help us out on this as well but my initial thought is it might be a good idea to try red to black on BOTH sides as it would not hurt anything, and seeing as how Cary is saying that it is phase inverted, it might actually be an improvement of somewhat. I remember that you said the highs were somewhat shrill at times, and who knows(?), reversing speaker cables on BOTH sides might have a positive effect on that. It is free and easy to try, and if it were me, I would try it.
