Ihave had the 775 for about 5 months now, and it has been playing almost 24 hours a day since then (so it should be broken in) and I can say that the MIT cables did make it sound much different. I used to run it straight into the DAC on my Sony TAE-1000ESD pre-amp, because it just sounded less digital. I am running a optical cable into a Audio Alchemy DTI jitter box then MIT T3 Digital Coax into the sony. When I added MIT 330 Plus interconnects, the sound really smoothed out. Not so much as with the jitter box, but really close. But it did have much more detail that was getting lost by using the digital out (although the vocals seemed more seperated with the digital). On badly recorded CD's I would switch to the DAC, but on most material would leave it analog. The IC's cost me $50.
