I do not know about Analog v.s Digital or endless variations in obtaining desired levels of performance ....... it is all very subjective.
On the other hand there are those reporting great results with Squeezebox Transporter (Modwright modified) and other computer based systems.
I can only comment on what works for me:
MacBook Air to Empirical Audio Offramp Turbo and feeding RWA Isabellina HPA DAC. DAC is used as a digital preamp as it features variable analog out and it has remote volume control. RWA also offers the option to power components like EA, Wadia iTransporter, various chip amps via optional power out (will share its battery power supply with one other component) on Isabellina DAC. This will ( has potential) have entire system of the grid. ITunes are controlled with help of iPod iTouch and free remote application from Apple.
I wouldn't go as far as comparing two formats or vote in either favor (although I have my favorites) but it is somewhat possible to enjoy computer setup without regrets.
