Hi Joe,
As of January 2015, we still find that downloading a 4+Gigabyte 24/192 album in a raw PCM format just takes too long to be practical. The bandwidth just isn't as widely available as it will hopefully be one day. I think that is why others compress their files into FLACs.
I do not know how iTrax works. That said, as far as I do know, those services that currently claim to offer raw PCM in the form of .aif or .wav files, as opposed to formats like FLAC, are really sending FLAC files, which their "download manager" software then expands on the customer's machine. Personally, I don't find this acceptable for Soundkeeper (as I wouldn't purchase such for my own listening -- I buy my high res on DVDs and then load it onto my server).
Aside from the fact that I'm don't want our files to undergo the extra conversions, our business model is for direct sales, so that the artists get the compensation we want them to have, without compromising this by introducing a third-party.
Best regards,
Barry
