I don't believe anyone is saying all digital transports are equal. This is quite apparent especially when looking at home speaker components (e.g. Accuphase's implementation of transport vs other brands, etc.). What we're questioning is if the digital out optical differences between AK1x0 & AK240. The assumption I personally made was that iRiver wouldn't have invested into changing the optical out from the AK1x0 to the AK240 but would be pleasantly (& welcomingly) surprised if they did.
Good but then why do you limit the possible upgrades (between Ak100 & Ak240) only to the implémentation of the optical-out ? Can't there be also upgrades in other places before the transmission-out ? ( reading, packing data...)
For exemple the Aurender x100 & w20 are Said to share the Same USB Implémentation, but I am sûre that the big brother (5 Time more expensive) still sound better even through USB. The price différence between the 2 can't be only in the output ports !
Same for AK ? IMo
