Not necessarily. To test all this I did an interesting experiment last night. I have an Arcam Transport / DAC and I plugged in my Mac via optical. The Arcam DAC (Delta 250) also functions as a sort of digital pre-amp because you can switch between 7 digital inputs (via remote) so there is no issue with comparative volume levels. All these then fed a Naim pre/power set and Ruark speakers.
The Arcam transport playing redbook sounds better than the same material via uncompressed AIFF straight from the Mac's internal HD no question. Intersting. What about comparing another copy of the same disc playing into the DAC from my DVD player (Pioneer DVD-575A) via SPDIF and switching between all three sources?
The Mac HD and DVD player are hard to tell apart. Maybe the DVD player has a slight edge here and there but this could be the SPDIF sounding better than the Optical from the Mac, even using a high quality glass optical interconnect.
But the Arcam transport sounds a lot better than either adding a sense of dimensionality and realism to the recordings. This is a fairly decent set up which would have cost around 3500 USD about 10 years ago, so not madly expensive.
Why does the the Arcam transport sound so much better? one possible explanation is jitter. It's coupled to the DAC via SPDIF but also has another optical coupling which carries clock data. Another perhaps is the Philips swing arm mechanism sounding better than a DVD transport.
Bottom line for me is if I want to listen to digital music I want the best reproduction I can afford and conventional CDs still offer this, mainly because the hardware is more mature I think.
Yes the ipod is convenient and lossless sounds great on headphones on the move, but at home I am prepared to put up with a little more inconvenience, choose which piece of music I want to actually listen to from the shelf and slap it in the drawer, when I can't be bothered with firing up my turntable of course....
