I believe you. It's usually the difference in output voltage at the terminal. They do vary from DAC to DAC and CDP to CDP. Once you match that voltage during testing, the audible difference becomes much much harder to notice, more like they become indistinguishable regardless of the price difference between equipments compared. There are some exceptions but I don't think you are referring to that, unless you've performed the voltage match during your listening tests. Did you? If not, you should try it before inviting people over for listening tests.
Whether or not you prefer the difference an external DAC makes in a particular system depends entirely on your preferences.
I agree, what I prefer depends on my own preference.
I know what sounds good to my ears and that's all I care about in this hobby.
I may be wrong, but you seem more concerned with proving people wrong with science and measurements than enjoying the music. That's fine if that's what you're into, but please remember that some folks are willing to spend money on their system even if it doesn't make a measurable improvement. That is their choice to make. If they notice an improvement and it makes them happy, then who are you to rain on their parade?
I don't. My replies aren't exclusively to you or anyone who just won't listen and think about. There are many lurkers on this forum looking to learn about AV gears and application of them (I was and still am one of them). While it's none of my business what people buy with their money, when they come on a public forum like this and start posting claims without any evidences to back up with or make no distinction between evidence and opinion, I certainly can call it out.
Now, if you are are just trying to justify not making upgrades to your own system and saving money, then I can completely relate.
I can relate to you because I used to be like you. I have done what you are doing (posting such replies on internet forums). Thanks to members on various forums who took time to call things out, I had an opportunity to learn the right things in audio and end up with a fantastic system without wasting money. I hope you will have the same opportunity as well some day.
