Listened to a Philips recording of Mozart's Requiem that is one of my favorites, and once again, there were several significant differences with the Cryo-ed plug. Improvements were most noticeable in the clarity of brass and the audible movement of air in woodwinds. All percussions were more clearly defined and placed.
On to a bit of pop/rock with Sting's Brand New Day. This one was scary in the differences- huge differences.
Soft background vocals appeared that I hadn't heard before. At one point (about 1:00 AM) I looked behind me to see if the wife had gotten up and had said something. Instrument placement greatly improved, percussions jumped with each strike. These were the kind of improvements that occurred when I moved up from a midfi pre to my Dodd- but the Dodd wasn't $10.
Summation in my system.
Percussion, bass guitar, lower piano register, lower guitar register all more defined, better placed, with less smear in time. Vocals more clearly placed and moved somewhat forward in the soundstage. Increased detail of instrument placement. Better soundstage depth, but not width especially (except on Sting, in which the changes were just spooky

).
Conclusion- In general, I am amazed at how the cryo outlet affected my system.
If you are still using the original outlets in your house or apartment, do yourself a favor and pick up some decent cryo-ed outlets- do it now. The Pass and Seymour's that Dave sells are an excellent value, and I'm sure that others are available from other sources that will also do the job.
