sound difference MIT ORACLE AC1 vs ELROD vs PURIST

I noticed that especially the BADA is subject to the modifications induced in the power cord. With the assumption that the final result also depends by the system as a whole, but what kind of change can be described with the addition of Elrod? or MIT cables?

I have the latest generation Elrod Silver Statement speaker cables and power cords. I don't find them to be dark at all. If they sound dark in the system look elsewhere as they are tonally the most neutral and transparent products (in their categories) that I have tried.

Thanks Linkster,
I acquired the ones which Zmanastronomy suggested me here on Audiogon. I Will test it and then I Will write here my notes.
one more question, the Elrod PC,s are specialized with regards to the components ? ( like Stealth for example: for amplifiers, for pre ....etc)

I spoke with David about the EPS-2 Sig on my amp. It's touted as a source PC, but he said it would work great on my Tube amp. And it does. In the same line of Signature series, the EPS-3 is for amps. So far the EPS-2 is doing fine.

I have not heard the other two offerings you mention however I can tell you out of all the other pcs, interconnects and speaker cable brands I've owned up and down the scale over the years, that I am EXTREMELY happy and blown away by what the Elrod latest generation cables bring to my system. They bring a transparency, energy, dynamic and realistic musical experience to my room that I did not think was possible and has been absent from many of the systems I've heard over the years at shows, dealers, etc...(even those costing 200-300K). I have Statement Gold PCs on my amp as well as pre-amp and DAC and they work equally well on all component types. You should definitely give Elrod a try in your system...
