Marantz SA-10 arriving Monday!

Iammatthewj, Sharri can answer your question.He is very knowledgeable. He posted on my thread SA10 needed repair.

Iammatthewj, I will try the inverted  phase on my SA10 see what happen.My Krell krc3  can be inverted as well, I think.

@jayctoy , it seems to me that as far as phase goes, there can only be one way that is right and then that the other way must be wrong.  When I first got my SA10, I did try it both ways, and my ears are not good enough to discern the difference.  However, with that last typed, even though I consciously am not hearing the difference, it still may be that my subconscious would find one way more pleasing.  (That subconscious/conscious thing gets a bit deep, but I do believe in it.)   Anyway, you are right, @sharri is quite knowledgeable on this stuff, and I reached out to him in your SA10 thread.

It’s always better to have the right phase. I do have XLO test cd where they demonstrated in phase and out of phase. That’s very informative.Post here what Sharri thinks.

@jayctoy , I have a couple of test CDs (at least a couple) with the in phase/out of phase track on it. I don’t have a real good grasp of this stuff, but the more I think about it, I do not think that this is quite the same thing.

I believe that the test track we are talking about would identify if one speaker was hooked up red to + black to - and the other speaker was hooked up red to - and black to +.

However, I THINK that what the inverted/normal switch on the SA10 does would be to essentially change the signal from red to +/black to - on BOTH speakers to red to -/black to + on BOTH speakers. In other words REVERSING the way the phase was supposed to be set up. I THINK that this may be known as absolute phase, but I am not sure because as I typed previously, I do not have a tight grasp on this.

In other words, what I THINK is that although you could hook your speakers up red to - and black to + on BOTH speakers, the system would pass the in phase/out of phase test track and would not sound all over the place when they performed the "in phase" announcement on the CD. However, I THINK that by hooking up the speakers as I just described, that would still have them out of absolute phase. At least this is what I THINK.

On another audio forum I once asked a question about a preamp I was kind of interested in that I had read the specs on (I seem to remember it being a modded Cary SLP98) and I remember reading that it was wired internally with the phase reversed. (Once again, I THINK that this would have been absolute phase.) My question was why would a manufacturer intentionally do this, and I do not remember the answer, but the solution was suggested to be, when using that preamp, to hook BOTH speakers up red to -/black to +. And that is what I am THINKING happens by switching around the INVERTED/NORMAL switch on the SA10.

Referring back to my original question on this subject, does "the European model of the wiring the balanced outputs on the SA10" mean that it is out of phase with equipment with the balanced inputs wired to the "USA model" and therefore, ideally, should the phase be inverted?
