Hello, I have the premium sound sound system (but doesn't matter for this particular issue). I tried to play a 24/96 hi-res album (outstanding recordings from Blue Coast Records - Piano "While She Sleeps"). The rendering is superb on my home stereo. In the Tesla, the file is playing really bad - lot of back ground sound and the actual music is playing at a rather low level compared to standard recording sounds. The file is a hi-res wav - But I have also tried converting it to flac : same sound : same issue. I am sure the file is ok (as I said : plays fine at home - and when I play it on my mac via iTunes (where it has previously been converted to itunes format - but still 24/96 hi-res) is it still ok : no loud back ground pink noise. So ok everywhere, except in the Tesla. It is not about 'is premium sound worth the upgrade, and so on'. 24/96 files from Blue Coast Records (one of the best recording studios in the world) are playing at low level with very much back ground pink noise. It is not an audiophile question - I mean the issue is very obvious and can be heard by anybody. Car is new from June - So it has the current firmware (6.2.xxx). Anybody with the same issue ? Explanations ? Solutions ? Thanks a lot.
