I have a Rossini Dac (non Apex) with Rossini clock. Latest updates and using the balanced output (2V) to a Grandinote Shinai integrated amp (full balanced).
Some week ago I noticed a clearly lower volume in the right channel and after about 15 minuter there was a moderate ”poff” in the right speaker and all of a sudden the full volume was back. Same thing happened a few times but now the right channel is permanent lower.
The unbalanced output is working ok with same level on both channels
If that is the case then I would suggest that your best course of action would be to contact your nearest dealer - that sounds like a physical fault I’m afraid.
Sorry, the message went away too early, I continue!!
When trying the unbalanced output all was working normally, same level on both channels. And moreover I noticed the overall output level was substantially higher than with balanced output. And to my ears the sound was definitely better as well with more body to the sound. And according to the manual it shouldn’t, rather the opposite.
Has anyone faced something like this? To me it seems like there’s something wrong with amplifying of the balanced output.
Just to add a little to Phil’s comment. Before contacting your dealer try to make sure that the fault is with Rossini and not the balanced input to the Shinai. To check simply swap the Rossini balanced cables to the preamp at the amp end so that right output feeds left input and left feeds right. Does the fault move from right to left channels? If it does then it is a Rossini issue. If it remains right channel it is more likely to be a preamp issue.
Either way this sounds like the kind of fault that cannot be rectified on an online forum. Phil’s advice is appropriate.
