I wasn’t at the Denver airport. I was at Centennial. But no one knows where that is. second Denver International is KDEN Third, KKIA is not an airport I can find in the US. No electron left behind.

Ralf11 Posted September 8, 2019 Share Posted September 8, 2019 I know where Centennial, Wy is... The new Denver airport was a huge candal and apparently a LOT of payoffs, corruption etc. was involved in its siting - certain developers made out big time. KIA is a joking name/ID for it.

AudioDoctor Posted September 9, 2019 Share Posted September 9, 2019 Centennial Airport is just south east of Denver. Centennial Airport 7800 S Peoria St, Centennial, CO 80112 (303) 790-0598https://goo.gl/maps/G6wSrAZzBTzK7kaL7 No electron left behind. Link to comment

Until next time boys... Funny in the context of MQA. They delete Will Smith's fingerprints to make him anonymous. But MQA claims to fingerprint DAC's and make corrections per DAC model, while in reality the filter coefficients appear all the same across different brands of MQA enabled DAC. Proof of DAC specific tuning still needs to happen ... All those canned MQA articles which claim this, and more pseudo facts which were already debunked (like that absurd third unfold), are similar to what happens at 02:33 in this video: esldude and Archimago 2 Designer of the 432 EVO music server and Linux specialist Discoverer of the independent open source sox based mqa playback method with optional one cycle postringing.

In the example wrote that was quoted on this forum, the PCM data fed to the DAC chip has a bit depth of 24 bits and is sampled at 192kHz. Nothing more, nothing less. John Atkinson Technical Editor, Stereophile All MQA certified DACs display the samples are actually authentication flags, i.e. this is similar to Roon displaying 'Authentication' in the signal path. It does not report the actual samples that goes to the DAC chip. This can be very misleading by looking at the DAC's display and assumed it actually 'unfold' to '192k' or even '384k'. To a average consumers, they will take it as it is. In my opinion, this is 'cheating', it does not reflect the inner working of the DAC😂 MikeyFresh, lucretius, Dr Tone and 4 others 5 2 Link to comment

It is covered by the authentication, so any alteration would make that check fail. Faking the signature isn't possible. lucretius 1 Link to comment
