I watched the video Zeos posted about the xDuoo TA-10 and thought to my self, i want a tube amp, i have wanted one for ages.
So then I went online and bought the TA-20, figured it would be great, also it is balanced with two tubes.
I have now received it and tried it out, I have not used it for that long as of writing this (3-4 hours) but I am at the point where i want to throw it at the wall!
I feed the thing with balanced audio from my SMSL SU-8 (I ordered it along with the xDuoo amp) but the problem is that I get a constant humming and hissing sound from the amp, does not matter if I trie balanced or unbalanced source.
I have also tried to feed my other amp (Schiit Jotunheim) with audio from my new SMSL SU-8 DAC and that works like a charm, total silence while I do not play any music.
The headphones I have tried are the Sennheiser HD 800S.
So here comes the question, is this hissing and humming sound from the xDuoo TA-20 amp normal!? Is it supposed to be like this!?
