I have not said anything against RME, in fact I have been using it and was very happy, can even recommend it, but its features were just overkill for me. It's all about choice and what you prefer.
I'm not supposed to answer your questions regarding your tone of your replies, but I will make an exception here:
- foobar w/ abx plugin with friend's assistance
- true rms multimeter for level matching
- RME set to Sharp, Topping set to filter 5
- 44.1kHz/24 bit FLAC files via ASIO
- everything on RME (eq, deemp, etc.) turned off, Topping sound control turned off too
- I'll give you two specific tracks with which I've been 100% able to always correctly pick Topping in the test: Nosferatu - Wild Side and Bon Jovi - Always
Make anything you want from it. And to all of you ASR cult followers who strongly believe that SINAD transparency threshold is always the only variable to imply that two DACs will 100% sound the same and that you cannot hear any differences between them, I would strongly recommend that you better look at THD vs. frequency plots and make your own conclusions from it.
I think there's lot more to it than just looking at the APx SINAD-king dashboard.
