I am not a hobbyist. I am an electrical engineer. Was raised in 1960s with analog design, put myself through college by repairing electronics. And spent 35 years in the industry and then semi-retiring. During that time I managed the development of both hardware and software products. I own a high-end AV integration company right now so I remain in the industry. I also write highly technical articles for magazines on deep concepts such as psychoacostics, digital audio, acoustics, etc. I was the owner of the first Audio Precision analyzer when I found out about the company shortly after they started while working at Sony (back in early 1990s). If this doesn't qualify me to measure the output of the DAC, then I am not sure anything will.
I am open to my measurements being in error. I always am. I have spent thousands of dollars of my own money purchasing the equipment I review (only a small percentage are donated currently). I am using an analyzer that retailed for $25,000 for the work I am doing. My goal is to increase the amount of information out there. You want to "flip the bozo bit on me" you can. But please don't give reasoning that makes no sense.
Remember when an automobile reviewer assess a car, we don't demand that they be an engine designer or they are just a random hobbyist.
Ultimately I agree with #2 though. It is totally up to manufacturer to decide what to do with my data. As I have said, some reach out to me to investigate, try to improve their products, etc. Others just get mad.

I am pleased to see Mike not being in the latter camp.
Anyway seems like we are just getting argumentative. My apologies to Mike for furthering that. If there is nothing technical you all want from me, I am going to depart so that regular programming can continue. My sincere appreciation for Mike for letting me interject for a bit.
