PS. On computer-audio differences, resident IT experts Marja & Henk had this: "It's a fact that with network communications (computer data transmissions) there are differences in ethernet cable quality. CAT 5 was superseded by CAT 6. When a standard CAT 5 cable for audio purposes gets switched to CAT 6, there's already a substantial audible difference. But it goes well beyond cables. Think hard disks. We notice differences using various hard drive makes/types for audio playback. In our XXHighEnd dedicated Windows PC our WAV/FLAC files store on USB 3 hard drives. From there data is intermediately stored on another disk before being transferred to memory from whence actual audio ‘playing’ is performed. The kind and type of intermediate disk has an influence on the perceived playback. Western Digital sounds less good than Toshiba where SATA disks are concerned. Disks spinning at 7.200RPM sound better than 10.000RPM spinners. Using a solid-state drive is not as fine/good as a slow-spinning SATA. So far the best is a RAM disk created in physical memory. Audiophiles have trouble wrapping their heads around the fact of no real time component since all data is cached and/or buffered somewhere along the path yet everything still has an influence. The only thing we can think of is that it has something to do with transitions between protocols. For an analogy, computer hacking occurs at the most vulnerable side of software - its protocol boundaries. When HTTP (which is nothing more than a copy protocol) transfers data from server to client (a web browser receives or sends data to a server), there's a conversion of protocols. At that crossing point hackers can interfere. It goes far deeper but the general idea is that at each crossing point from HTTP to XML, SQL or whatever protocol is involved, there's a weakness and an opening. The same seems to be true with audio content at a low level. In computer audio data migrates from one protocol to another. At every protocol translation point there's an influence."
