I have a feeling that this unit is sensitive to a shared ground. The no output into my ARC LS16MkII was solved with Interconnects with thinner RCA Connectors. The locking connectors on my Audio Magic Excaliber II cables were touching and it may have caused an issue. I must say this is a great sounding Pre-amp, but a finicky one. I have not heard from either iFI or Music direct yet though. No heat or other issues since changing out the interconnects. Since the AudioMagic Excalibur II cables barely touched I will Isolate them with a barrier since they sound better than the Canre based DIY's
playing now.
From the ifI Knowledge Database:
My unit stops outputting audio, is it possible to reset?
It is DC coupled and can "go off the rails" if there is a large DC input or very high levels of AC (e.g. the 115V/50Hz a "missing earth / ground" audio system floats at).
This "latches up" the device, it needs to be unplugged for a few minutes and then restarted to be reset.
There should be no problem with a properly earthed / grounded audio system, only if there is no earth / ground present.
Does this mean a ground from the unit to the pre-amp is needed other than through the RCA's. None of my other phono pre-amps require it.
Thoughts?
