    Topping E70 Stereo DAC Review

    Perhaps, to be more clear, I'll add sterile as well. But, as I wrote above, I don't feel like getting into polemics. There are as many people on earth as there are individual judgments about sound, color, etc. Here I have shared what I feel, but by no means would I want to impose anything...

    Topping E70 Stereo DAC Review

    Yes of course. Otherwise, why waste my time, money and warranty, if I can't hear the difference? This action was not dictated by "someone said, it was better", but the result of many experiments and DIY projects. I hope that's enough and I don't want to get into unnecessary polemics.

Regarding the D10s SMPS, as far as I remember, there is no SMPS filter, and it is possible to break its...

    They could put audio capacitors where necessary, but Chinese, as always, want to go as thin as possible.

    SMSL SU9-n issue

    I think the Si5351A is not the right one. Please check the pinout of Si5351A and PCB layout if they match. Good luck!

    Measurements: "ESS Hump" revisited (Khadas Tone Board V1.3)

    That's right. Anyone can make it from a piece of 2mm copper wire.

    In fact, removing these SOIC-8s takes about 2 seconds if there is no thermal pad.

    Topping D10s USB DAC and Bridge Review

    Look, I'm sorry to say this, but I have neither the strength nor the nerve to argue on the subject. Buy OP and test. I said what I meant to say.

    Topping D10s USB DAC and Bridge Review

    Not good idea. OPA2134 is mediocre quality today. The best sound, from the experiments I have done so far, were ADA4898-2 and OPA1612. OPA1656 is not suitable, or at least not in this buffer variant. But, it's best for you to figure out how you like the sound the most.
