AUDIOPHONICS MPA-S250NC Amp Review

So then Audiophinics reply to me that it is normal and that the EMI filter causes this in all units is not true...

Maybe it's my ears' i don't know

Not even if you put your ear close to the unit?

No. It's dead silent.

Ok. I'll guess I have to write to them again then Here goes nothing.

I am sorry to hear that. I recently bought it and my left and right channels where reversed. Audiophinics did not help me at all and actually told me to open it up myself and switch the connectors inside. It is actually going against pretty much every regulation you can go against. I hope my unit will last longer, but I am never doing business with them again.

AUDIOPHONICS MPA-S250NC left and right channel reversed

So I just got this and to make left and right separation I actually have to put the left hand speakers into the right hand output of the amp. I am guessing this is not normal behavior and that my amp must be faulty right? Already tried another preamp to see if the fault was there but same result.

Glad you were able to fix it.

Yes but there is still that buzzing sound though...

I’m using the XLR version to power an open baffle dipole sub by Siegfried Linkwitz (LXSub4).

This amp works perfectly, initially I planned using a Topping PA5 II but had no chance driving the speakers.
