I apologize to Joe for taking so long to reply. The Electraglide S.O.T.U. is a very good cord, especially for the prices that I've seen it selling for on auction. FWIW, I now have two of them. Their positive attributes are speed, clarity and resolution, similar to older Electraglide cords. However, they are not quite as thin sounding as the older cords, IMHO.
I would lump them in a camp with the likes of Nordost Valhalla (I prefer the S.O.T.U.), Stealth Dream ( I prefer the Dream) and the Ridge Street Audio Poiema!!! Signature's as far as clarity, speed and resolution are concerned. However, if you're looking for a cord to add warmth or musical weight, the S.O.T.U. is probably not the best choice.
My speakers are warm (Verity Parsifal Encore's), I'm using the S.O.T.U.'s on a VAC tube integrated amp and a Marantz modified CDP with a tube buffer stage. So the added speed, clarity and resolution fit well in this system. YMMV.
Cheers,
John
