Apple have rendered the digital outs included with their products worthless.
After moving to OS X I've never looked back until now. Despite recent improvements in the windows itunes incarnation, itunes for mac os X is now implementing poor quality sample rate conversion regardless of settings in the audiomidi setup utility (applications>utilities).
Try it for yourself listen to a track on VLC, then on itunes. In fact I'd noticed this difference before even hearing about what os X is doing. This may well be unnoticeable to the casual user, but having invested money and time in hard drives to store lossless CDs an external DAC, good speakers and a half decent amp I feel let down by Apple because they have taken this step backwards from bit transparency and negated my expenditure. Unfortunately VLC does not come with any form of Library. I'm now looking for alternative media/library players.
Why there isn't an on off feature for sample rate conversion and even sample rate switching as opposed to mac OS X's poor sample rate conversion is beyond me. I was ready to accept being tethered to itunes by apple's array of snappy products, which when considered as a bundle represent good value IMO, but now I'm thinking of moving away.
I invite apple to address this issue NOW instead of messing around developing better versions of itunes for windows before OS X looses any more credibility as an audiophile system.
