sound difference MIT ORACLE AC1 vs ELROD vs PURIST

I have at one point and it proved to be a great upgrade for the entire system as it brought great power to the main distribution point for the entire system. At present, I have it back on my amp and am planning to find another one as soon as this is practical to connect from the wall to my Purepower unit as I want that performance jump back in the system :-) !

Just arrived the Statement Gold.
I insert it between the ac outlet and the distribution. First impression, (a couple of minutes only) more reality in every musical instrument. The mids are much more natural without the slightest hint of hardness. Fantastic cable, it is also nice, a statement which made ​​my wife smile a lot.
Having read many comments around, I guess I'll have to wait a certain period so that the cables are able to give their best. After this period will insert my contribution.

The cables do sound great on day 1 however you'll want to give them a few days to start to settle in and at least 300-350 hours to fully break in. Enjoy!

I had a bit of time over the weekend to test and enjoy the Elrod Gold Statement PC.
The sound of my system in general has become more deeper, natural, real, with great presence of details while maintaining and enlarging the third dimension. The presence of detail it goes with the sweetness of midrange and treble. The sense of palpability of the instruments is real, truthful.
The audience never gets stressed out by the vehemence of special instrumental passages, especially in the case of orchestral pieces.
I am truly amazed by how it has changed the whole system sound

All the things you mention are consistent with what I've heard when I've added them to my system as well. It's amazing what a great PC component of this level can add to a system and help it realize
