I've got all my music stored on a server in my basement. It's all FLAC, ripped our bought (or borrowed ;-). I'm now looking around for a good DAC and Amplifier (or a DAC amplifier combo). in that context I ended up talking to the owner of a local HiFi store who made some quite remarkable claims I find hard to believe.
The first claim was that playing back a FLAC could never sound as good as directly playing the CD is was ripped from, no matter how good your hardware. I found that claim hard to believe. Electronics is deterministic. If you play a bitstream to a DAC the result will depend on the quality of the bit stream and the dac, but should not depend on what is producing the bit stream. A CD transport feeding a DAC should yield the same sound quality as a network transport feeding the same bitstream to a DAC.
The owner then said that the source of the bit stream mattered, and he went on to claim he could hear differences between CDs pressed in the US versus those pressed in Europe. (and ofcourse the Europeans sounded better....)
Is that possible? Is it really that two CDs, which both contain the exact same sequence of bits, can sound different because they were produced at different plants? I find that a rather far fetched claim.
