MSB DAC II vs DAC III or others?

I'm doing similar research, but I thought I read that the were not much different electronical, that the Link III was just an easier ugradable version of the Link II either way you might want to check out MSB's Trade In policyhttp://www.msbtech.com/upgradeoptions.html Good luck

Yes, My understanding also is the Link I, II, & III are the same unmodified. Each improvement is just an easier upgrade.

Might consider checking Stereophile this month has MSB III review. Regards

MSB dealer told me that he couldn't tell the difference between a nelson upgrade or not...he says its not worth it, better to go to the updampler or power supply.
