Overtureaudio, I'm happy that you've raised this issue in a public forum so that it can be discussed openly.
Over many years of experience with Spectral, I will state that in my system (dmc30sl, 360's, 2000/3000), the ZII on the preamp and digital sounds closed in, dark, and dulled. It may be fine in other applications, but not with Spectral's best components. The Oracle 3 is not a great choice for the preamp either, contrary to my year-old discussion above. However, since you are recommending the Oracle AC1, I believe that MIT themselves state that the Oracle 3 ( Oracle 3 = Z III), when used with the old Z-stabilizer box is very close to or the same as the Oracle AC1or AC2 cords. Therefore, I interpret your statement to mean that you think the ZIII should not be used alone, but instead with a line conditioner (?)
Since you say you don't recommend the ZIII for use with Spectral at all, can you give technical reasons (inductance, capacitance, shielding, dielectric) why not? I use ZIII's with the dma360's w/o conditioning and with the 2000 into a line conditioner, and find that they work well there, so I'm surprised at your conclusions.
I'm also interested in hearing from Spectral owners on what a/c products work well with the dmc30sl and digital. Power cords that do justice to fast sold state and retain the detail and dynamics, along with transparency and a lack of coloration are not easy to find among the plethora of a/c cords on the market.
