It's none of your business who designed any of my boards.
If you look at the board characteristics it's fairly easy to see the board houses each board came from.
Oh, it is absolutely clear. You took a board from a respected designer and ruined it by sticking it in that box of yours to sell with no regards for safety and performance of finished product.
Wow I guess that makes me an awful fool. Nobody who works with us would waste a second of their time around here. I can assure you of that. However they have been following this shit show for a good laugh
The shit show we are dealing with are your posts. In time I am sure the industry people will read these posts and realize to be very careful in dealing with you on ethics front and surely on competence. They would be much better off going to source of your product as I linked than dealing with someone like you who doesn't know the meaning of the word professionalism and truth in communication.
So I will confirm and unless you put forward any data that can be verified, these are the facts:
1. No measurements of your entire DAC exists. You don't have the equipment and necessary knowledge to measure it as evidenced by incorrect quoting of specs.
2. Your DAC board was designed and created by someone else. You have no knowledge of its internal design and any credit for good performance belongs to them, not you.
3. No industry person with professional engineering experience would ever, in a million years, defend the kits you have put together from safety or performance point of view.
4. You have no understanding of measurement science or psychoacoustics. You ramble off subjectivists PR line while at the same time raving about component specs that those people don't care about and at any rate, are not for the whole product.
Those are the facts and would be evident to anyone with an ounce of engineering knowledge.
