Na realidade um Fiat 500 e um Rolls Royce...são dois carros ...MAS...!!!

O Fiat 500 é melhor para dar um passeio na praia e ir à esplanada no verão.

The naivety and cluelessness  of this article are so fresh. Was it written by a 14 year old?

It could have made sense in 1986 or perhaps even 1996, but 2016?!

Talvez seja porque a SOS é uma publicação destinada a DJs, produtores etc. A pessoa que escreve o artigo é consultor técnico, mas deve estar mais á vontade com material pro, provavelmente.
Em 2016 ainda era norma os DJs usarem cds para os seus shows, mas isso também já passou á história.

We are all a little naive sometimes... but, and focusing on what is important, something untrue in the article?

It assumes bit errors are what separates cheap from expensive transports. This has been proven to be a red herring some time in the 90s and is even easier to prove today.

Can you provide proof?

Done this at the time when i still used an optical transport - more than 10 years ago. File received from spdif stream bit- compared to file obtained from EAC. Tested on two transports with unscratched cds. I bet it is possible to find a transport which introduces bit errors, or even easier: find a defective cd with unrecoverable errors. But a reasonable quality transport and non defective cd generally produce no errors.

Besides, thousands of HDCD encoded cds have been successfully played on single box cdplayers and transport-dac combos. The nature of HDCD encoding demands bit perfect reproduction in order for the hdcd decoder to work. The easiest way to confirm bit perfect stream is to monitor the active pin of the hdcd decoder. It was fun at the time, but getting really tedious today. Who uses cds anyway?

Not that much has changed today. Non-optical transports continue to sound different despite being bit perfect. Engineering types continue to scratch their heads
