I tested a PS audio directstream DAC. It measured poorly in low frequencies. After a bunch of back and forth with claims you believe in, it turns out that for cost reasons they used low quality transformers that produced more distortion! Multi-thousand dollar DAC used low quality parts...
Don't be so naive. All manufacturers have price points. If you do not like the sound of their DAC, move on. Buy something that sounds better to you or tear them all apart until you find one built like you want it. Danny, a real audio and measurement guy tests and tears down speakers costing thousands of dollars and shows us the low cost parts inside. The speaker was built to have a certain sound and performance for its price point. It is not a gotcha game. It is the realities of business. Danny also designs upgrade kits for these speakers that one can buy if they are interested in improving the sound. Every piece of gear has room for improvement no matter the cost point.
Something more useful might be durability testing. HALT testing (Highly accelerated life testing) on gear to find the weak points and define the useful life of the gear would be interesting- but costly.
