[QUOTE="pwatts, post: 700140, member: 146"] There are a whole bunch of folks who claim to hear the difference on their streaming endpoints made by down-trottling CPU speed etc, claiming that higher CPU activity leads to a slew of afverse effects such as power supply-induced jitter etc. Considering that modern CPU's can cause spikes of several Amperes it's not entirely implausible so I'll at least be willing to hear them out. Now a FLAC file requires real-time decoding which means increased CPU load and thus susceptible to the same concerns. Therefore, my (implausible) theory is that the claimed differences are not related to the difference in content, but the difference induced by virtue of raised playback efforts. By the same theory, if the entire file is pre-decoded into a RAMdisk and the raw PCM data replayed from there afterwards, it should sound the same as a native PCM file. ...lotsa use of words like "potential" and "perhaps" in this theory though.
