Conrad Johnson ACT2 against Audio Research Ref 3

"What Guidocorona said was that he had the wrong setting for the type of I.C. that he was using. You don't set it for S.E. and then use balanced cables or set it for balanced and then use single ended cables."

Guido as much as I am a believer in the Ref 3, Agaffer is right on and absolutely correct in his observation. There should be absolutely no difference in SE vs XLR balanced output on the Ref 3 other than approximately 6 Db of gain

Oneobgin, best thing is to try things out. You can likely perform some tests before I do. Please let us know your results.

I understand completely what you did with the remote. There is a button that determines SE vs balanced. Your demo was running balanced cables but you hit the SE button which reduced the gain in your system demo. I am not even certain because I haven't tried it with my Ref 3 (but I will) what happens if there are only balanced interconnects and not SE and you hit the SE button on the remote. At the very least you will suffer a 6 Db drop off, but maybe even worse because you had no SE cables.

Bingo Doc. But it could be even worse than that. . . the button likely shuts off one half of the Ref 3's circuit--that is the signal return path. The 6DB signal drop off is but a sideeffect.
I should like to point out that when the event happened, raising the volume on the remote did not correct the degradation of the signal. Furthermore, I was not alone at the time, several other people, including Aris Audio's Scott haver observed the degradation.
On the other hand, it is quite possible that a sound difference might be detectable only on some totally balanced systems.

Oneobgyn, Guido -
As you are both owners, see if you can find out (from ARC?) or elsewhere, what the purpose of having that button/circuit change is for. Given that there is an audible degredation of sound, it appears that the REF3 works best in balanced mode rather than in SE mode, or am I mistaken.
