Bit perfect in music has another variable - time...and their lies the problem. So it has no meaning if bit perfect is being retrieved and sent to the destination with timing errors. That's why there are so many expensive sources like innuos. Computers are noisy sources. The innuos minimizes the timing errors by big and clean power supplies and avoiding switches. people need to realize electric circuits do not understand 1s and 0s. It is all volts/currents and errors are in various forms. Consider reading a book on digital circuitry and you will quickly realize how complex this topic is and cannot justify by saying bit perfect.

There is only less bit imperfection with better power supplies and clocks. A simple computer is completely bit imperfect. A computer is bit perfect though otherwise it would not work. Signal integrity includes the clock, jitter, noise etc. an eye diagram is a perfect example, the whole point of them is to ensure the data received is the same as the data sent. Using USB or ethernet allows the data to be buffered and then we only have to worry about the DAC local clock, instead of reading 256 bits for every 16 bit sample in real time (allowing for Reed Solomon) from a spinning disk...

The PS audio is not even using a dedicated cd transport but a oppo dvd player transport In an era of streaming network-attached digital music sources you might think the time for listening to music as played from spinning silver discs is past, but that isn’t necessarily the case. In fact, if you have read between the lines of commentary from many of our reviewers you might have noticed a quiet trend; namely, a softly spoken preference for the sound quality of music played from discs as compared to the sound of the same music played from network-connected players or servers. It’s hard to say what accounts for this preference, but one explanation may be that top-shelf disc players are able to harvest audio data from discs with very few read errors (and thus minimal intrusion from error detection and correction algorithms) and can likewise present that data in as jitter-free a manner as possible. If that’s the case, then high-quality disc players may still enjoy a worthwhile performance edge vis-à-vis typical streaming solutions, meaning our prized disc collections might in turn have a new lease on life Its the audiophile Luddite syndrome: CD's are better than streaming. LP,s are better than CD's... Ralf11, crenca and jabbr 2 1 Link to comment

So the best way to understand - is to listen - otherwise we will be blue in face talking in theory especially since this is not an IEEE forum but an audio forum. What theory, there has been zero technical content... We are not in the infant stages of how electronics work, or how signals flow... Thats why 5G is being rolled out and we now have LIGO...

Popular Post marce Posted January 10, 2019 Popular Post Share Posted January 10, 2019 I really hate this reaction to science and engineering, if its not sitting comfy with your beliefs its trolling... But only when its the so call objective side doing it... How do we promote being an audiophile as a hobby and attract new younger members? Maybe not be as elitist. jabbr and Ralf11 1 1 Link to comment

It's a reaction to the superior and baiting attitude adopted by a newbie poster. Ok I can agree with that especially since you have previously mentioned Orbital and Sasha (many a happy night at Reconnaissance in the 90's). The_K-Man and diecaster 1 1 Link to comment

marce Posted January 16, 2019 Share Posted January 16, 2019 I presume you did see the smiley face on the post that started all this, never mind the snarks comment. It was a more humorous reply to recent activity, the emoji should have indicated this... It was a GUTB response. At the end of the day its not what you listen on its the music that's important.

My limited understanding is smoothness could best be measured using data logger, which is much more of a measurement on the driver than of the car. In racing, I believe many dynamic characteristics of the car can be tweaked on the fly these days on the steering wheel in top echelon classes like F1 and WEC LMP1. This strikes me as rather different from the fire-and-forget mentality that many in pursue of audio accuracy are shooting for. Car #86 in MF Ghost is red. MFG is the sequel to Initial D. Yep racing wheels have very complex electronics these days, a single board computer with DDR all the interfaces and graphics. Link to comment
