Hello friends,
i used the search function, i sailed the whole web, i did my due diligence.
Well, this DAC
https://www.aliexpress.com/item/1005002810554110.html?gatewayAdapt=glo2deu
which seems to be 100% analog to the teradak here
https://home.teradak.com/products/107.html
seems to suffer with a low level hiss (how could i define that? HF intruding anywhere?), which with audio files with low DR (classical music mostly) is really a pain.
My config is an underclocked (though it did not help) rasp 3b+, isolator board OSA electronics (with and without board no difference), the tda1387 dac.
At first I tought it was a faulty item, so i bought it again, the deluxe version this time, to discover the problem is common.
I don't know whether any of you experienced this issue or it is a common problem, it's quite a pity since the sound coming out of this system is very pleasing...
Is there any known diy workaround?
Thank you as always,
Mike
