This is interesting.
I know there is a vast amount of difference between CD transports and digital sources but aren't we just talking digital information here, 0s and 1s. I've always been of the school of thought that just as long as you get those 0s and 1s to the DAC fully intact then I can't see how it can affect the sound, the analogue conversion at the end is what we hear, why would the transfer of the digital bit to the front end make any difference? Its the DAC thats the most important bit.
I know of a number of players which use very cheap transports even the Naim DVD5 player for one. IIRC its a very inexpensive Teac DVD-ROM drive that simply been adapted to work in the player. These Rom drives could be picked up for less than £20 at one point. Another 'high-end' CD player to use this exact transport was a Resolution Audio Opus 21, which again uses 1704 chips although a slight variation I believe 1704 J's.
These days however it's usually files we play from 'sometimes' even solid-state storage, so I can imagine the digital transfer method is only going to be even better, well maybe not better as there is only one way to deliver a 0 or a 1 fully intact, let's say faster and more stable then. The naim DAC was supposedly one of if not the first ever jitter-free DAC as well so as long as those 0s and 1s are getting there I can't see the point of spending huge money on anything that doesn't do any more than this.
