It's been done to death, long before he made his measurements, with clear instructions and explanations. It was his choice to release incomplete and erroneous (in the case of the iPod) measurements.
The TP lives in its own reality distortion field anyway, given its ridiculous price, its utter lack of features and its obvious technical flaws (high frequency roll-off, high output impedance). Measurements will only convince those who are already convinced. Audiophiles will buy it no matter what. Subjective and objective comparisons will be rejected on both sides, respectively. This is a dead-end.
Do you actually know that the iPod measurements are erroneous? He suggests more than once that he thinks the device is faulty. I've now seen different people assert that the test or tester is at fault, not the device, but nobody says why they think so.
Does price matter in assessing sound quality? I think price is subject to very simple market forces that Mr Altmann seems to understand very well (and which may account for his cheerful writing style).
As far as I can tell the high frequency roll off is inherent to non-oversampling DACs and this is not being introduced by a low pass filter or by his design error. In this case are they all technically flawed?
Can one say that a device for playing music is flawed without hearing it, on the strength of some apparently inadequate measurements? If so then why would anyone need to perform listening tests?
How awful a crime is 10 ohm headphone output? He publishes the figure and states prominently, clearly and more than once the headphone he used in designing his player. I have similar Koss 60 ohm earphones running from a receiver with 8 ohm headphone jack and it drives them well and they sound really nice. The same earphones on the Clip+ sound quite unpleasant because despite its better/lower impedance it hasn't the power to drive them. So power matters as well as output impedance and sometimes it matters more.
In saying "This is a dead-end" you might be right but then why bother commenting?
The part of the article that interested me the most was its short description of non-oversampling DACs and links to more detailed discussion and description. I tried to remember all the CD players and DACs and receivers and MD recorders I've owned, dating back about 20 years, checked the specs via google and I'm pretty certain I never owned a NOS DAC. I realise that I might never have even heard a non-oversampling DAC, or at least been aware of it. I also can't afford one right now.
I can read Mr Altmann's entertaining prose without feeling tempted to make him richer, or angry that he makes stuff I can't afford, or annoyed by his claims or methods. I don't see anything from him that justified some people suggesting he is dishonest or deceitful. I have seen that he is disliked and even libelled by some people who have no relationship with him, and that his player is disliked by people who have never heard it.
