Dtc,
All else was equal in my evaluation of Lossless vs WAV & AIFF, error box was checked, I used I-tunes & Squeeze Center. With the audio playback gear I use the difference was clear. It was a disappointment as I had ripped hundreds of cds in Lossless based on what I'd read in the forums. Then when I received a highly modified Duet from Gill Audio run through the Gill 'Ellise' DAC, I was totally underwhelmed, I thought there was something wrong with the Duet, but was told to try a WAV file... and there it was, all the subtle cues that make music. So I don't know if Apple Lossless is losing info or what, I do know that on a revealing enough system it sounds flat and lifeless. I would hate for someone to rip their collection to Lossless and sell the cds only to find later that it isn't as good a format as had been said.
thanks,
Lou
