Is it an intermittent connection, with any cable?

Hmmmm...maybe its the cables. Perhaps both my 2.5 and 4.4 cables have failed simultaneously. I pulled out the 3.5 cable (almost forgot I had it) and no problem.

My MMCX connector got bad some time ago and I soldered the cable directly , they have nice construction and they are not hard to open , you may change the connector without too much effort as well

If needed I will muck about. Perhaps my quick fix will be to buy another 4.4 cable; the old 3.5 seems to be working after all. It is actually the first time I have used the single ended cable.

Man, I hate to hear that Snuff there are some talented guys out here who dabble, if it’s just a wiring issue you can probably get them repaired.

Might just be cables going bad. Hope that is the case; it is a cheaper and easier fix!

Most likely, the problem is still in the iem's connector. I also lost contact, and then the inner half of the copper connector in the earphone fell off. I gave it to the local master, he changed the connectors on both iems, and he said that the native connectors were of poor quality.

Have you been changing cables on it? Or stuck with a single cable all the time?
If you changed then it could be the mmcx socket on the A7, LZ mmcx is not very good...(my A6 is dying because of it)

Yes, I had been changing cables. Last night I was bummed when I changed from a 4.4 that was acting up (actually not acting at all in one channel), and went back to the 2.5. It also had the same problem so I assumed the issue was the A7. But another comment inspired me to go find the 3.5 cable that came with the unit. And sure enough that worked just fine. So I am concluding, for now, that the problem is cabling and a new cable is due on Wed.

Nice enough, Penon offered service after I sent a late night email. Which I thought was very responsive. I may not need the service (to be determined) but I was happy with a quick response. Makes me even happier to purchase from Penon from time to time.

I did discover that the lower noise floor does make a balanced cable approach worthwhile. I had thought this was black magic but there was a subtle difference.
