100.0% agree, normal engineering. Nothing special, just I made it as for myself, that's it. In most cases poor design could be explained not only ignorant "engineers" were involved but "economy" if not say greediness. I remember I was shocked when I saw the DAC+HPA with 100 pounds retail with nickel-plated 3,5mm jack! The difference vs gold-plated is a couple of cents, and in case 100mlns pcs/year it is worth to go but this is the same useless DAC like cobalt and other junk(my snapdragon855 based android has comparable power, and a lot better THD+N, SNR!), no way to sell more than 10000/year. So what is that, /year is economy? Some buddy asked me:
- why you care about the gold-plated PCB in your DACs if nobody can see that?
Ha-ha, I can see that, and it is enough
PS: about MQA, it is lossy compressed format like mp3, aac, aptx and so on, I don't understand how marketing-guys did explain that it so nice and even "improves" original uncompressed tracks. I tend to think about that like about the mp3 rebranding, if finally, users pay for that, marketing won.
