So you're accusing Emotiva of not using differential output on their XLR connectors? I can borrow my friend's O-scope, but I highly doubt that.
I never accused anything. I asked the question with honest intent 3x's on the Emotiva's forum thread for the 7030 processor. I was attacked by a couple of Emotiva readers, but my question remains unanswered by Emotiva mods or staff. I asked the question as simplistically as could be asked, given the scenario I have RCA cables, if I get XLR cables will there be any noise reduction potential with using the XLR jacks on the 7030 XLR output over using the RCA to my Sherbourn 7-350 amp or are the XLR on the 7030 just basically adapters and not trully balanced output. Three times I raised the question. The mods answered other questions around mine. Someone in this thread got an e-mail and posted it publically where the Emotiva CSR said the XLR adapters are not balanced output, but only balanced input. That would mean that the XLR outs are effectively adapters and not truly balanced. The question I asked was simple. There were multiple mod postings around my question to other questions, but not to my question. Based on the above, and still yet unanswered question in the thread - I am forced to surmise they are effectively XLR adapter outputs and will not produce a benefit over using the RCA output jacks on the 7030. No secrets here and no ill wished. I was just trying to get an answer.
RCA to XLR cables are passive, cheap, and to the majority of users will make not difference. It could EASILY be wired this way internally. In fact, if the 7030 does this it wouldn't necessarily be a deal breaker for me. it was the other bugs that scared me off. Though I would like to try true balanced XLR outputs because I get a soft hiss out of my pro amps and the 7-350 amp from the RCAs now on my Oknkyo AVR TX-NR1007.
Here is a $4 adapter that convers from RCA to XLR passively -- Obviously the connection wouldn't be balanced - but would be unblanced and still work (without the noise reduction benefit) I have cables like this I use now.
