The optical and coax inputs connect directly to the main PCB, the upsampler board plugs into a series of pins on the mainboard. I haven't used the AES/EBU input, but according to a Stereophile review it is a subtle improvement. THE best immediately audible cable improvement I have made with the Link is to use the Sound Professionals glass toslink cable,although this won't help you since I don't think the Monarch DIP has a fiber optic output. I sold mine when I installed an Audiocom Master Clock and P/S in my transport.
If you don't want to hassle with upgrades just get the Link II with the Monolithic P/S, use the coax and be done with it.If you change your mind you can always have it modified by ModWright at a later date. Good luck with your decision!
