[QUOTE="Igo, post: 8415802, member: 667005"] Greetings Cincy, I have been installing aftermarket audio in my vehicles since [I]Craig Powerplay[/I] in the mid 70s but have just now started pursuing the same questions you are asking. I'm not sure I have an answer yet but will share where I'm at. Most of us older guys know that easy file transfer and download speeds are why the MP3 came to be. They are a reasonable facsimile of lossless audio file formats when played on modest equipment but they toss roughly 90% of the subtle nuances that give well recorded music depth and character when listened to in a proper listening environment; which for the purpose of this conversation could be anything but a car, lol. There are 2 things that happened in the late 90s that have had a great influence on the norms of car audio even today. 1) Internet speeds reached a point that you could download a 3.5MB MP3 file in just under 15 minutes and hard drives became large enough to start being easy to amass large media library's. 2) With the former being said, everybody jumped on the aftermarket audio bandwagon. But I believe the next great auto audio evolution is on the horizon. This evolution has to have 2 things happen but only one is truly being addressed with any real vigor. I'll explain my thoughts. Car building technology is advancing at such an incredible rate. Extremely high performance cars are becoming very quite inside in cars where the purchaser chooses to buy a car at this performance/luxury/quite interior level. Also, people who really want to listen to the music on long drives are using sound deadening, deflecting and absorption applications in less expensively made automobiles to vastly improve the listening environment of their vehicles. At the same time, processing power and speeds of modern electronics (car stereos) and the prices of these advancements are improving are a blindingly fast rate [I]and[/I] the cost and [I]physical[/I] size of media storage is tanking at an even faster rate while its storage capacity is going up even faster. I believe we are at a crossroads where the MP3 or wma file will soon be challenged for there supremacy in the audio world.

The simple stereo in my car right now is such that I can detect the difference in playback quality in an MP3 and a CD very easily. What a waste modern audio equipment is when having an MP3 played through it.

I don't think automobile interiors are going to become quite enough in the next 50 years to worry about DSD but I certainly agree that it is very discernable the difference between MP3 and wav files as heard in a newer car and I have to agree that Satellite radio is absolutely grating on my ears and I won't have it. I will be watching here to find out if there is more to know than I have been able to dig up in the last few weeks. [/QUOTE]
