I've heard only the Mk II. I bought two sets after trying them out. I bi-amp vertically and have the Links on both the upper and lower. The result is quite significant, in the same way a good interconnect or speaker wire is able to remove a layer of haze or noise, the Links will do the same. I have experimented with them while using a number of different speaker cables. No matter how clean the signal is, they always cleaned it even more.
So why clean your signal? The result is less fatiguing, cleared highs. Better leading edge of notes, better imaging and a bit more definition of sound stage. I recommend the High Definition Links strongly, but the cost is an issue. If the over all set-up has any major weaknesses I'd consider addressing them first. The Links are not the final tweak, but they come well after good components and good cabling.
