In the fall I had a chance to home demo a full set of JPS SuperConductor 3 ICs in my multichannel system and a single pair of JPS SC3 speaker cables to front left and right speakers for a few weeks. I found the JPS SC3 to be very "beautiful" and even "beguiling."
I got one pair Grover SX non-teflon dielectric w/aluminum incoroporated speaker cables and the first 2 pairs Grover SX w/Al and non-teflon dielectric
ICs just in time for a one-weekend overlap while the JPS SC3 speaker cables and ICs were still on hand.
I initally found the Grover SX w/Aluminum to be sonically "competetive" with the JPS (and much more affordable).
In comparison I found the JPS SC3s to sound too "sweet" (beyond natural) in my system to my ears.
I sent the JPS SC3 set back on that Monday morning.
Below is my December Audio Nervosa post re Grover SX w/Al and non-teflon dielectric ICs and speaker cables:

After placing my order for "upgrade" to Grover SX I asked Grover and he confirmed that he did have examples of his previous cable versions on hand. I discussed with Grover by phone and e-mail my impressions on previous Grover IC versions up through Grover "SC" and "SCdot" and even particularly highlighted what I felt was pretty much an overall consensus that the Grover (S) "graphites" had exhibited the most "edge" or "grain" of all his designs and that the Grover (S) white/white were perhaps liked the best (detailed yet balanced frequency-wise and with perhaps the least edge or grain).
Grover acknowledged that some iterations could have been sideways moves or even a step backwards in some areas.
Grover sent me 2 pr. Grover SX with non-teflon dielectric and aluminum incorporated for audition.
These were very good and for first time I felt this particular version of Grover SX were if anything a tad on the "musical" side of the detail vs. musicality "knife edge" and might could be further tweaked to regain a bit more detail and extension while still remaining sufficiently "musical." I conveyed my impressions to Grover.
On November 14 Grover e-mailed "...Sorry for the delay, I changed the Sx again so you'll be getting even better cables. ..."
On December 4, I finally received my order of 6 pairs 1-meter and 2.5 pairs 2-meter Grover SX ICs w/ RCAs. These are, as I asked for, an apparently "finalized" version with non-teflon dielectric and incorporating aluminum.
Grover's e-mail said "...these new cables are much more labor intensive. The good news is I don't plan any changes. "
These ICs were installed in my system and have been in use probably 6-8 hours per day since late on December 4.
I find these to be "neutral" in frequency balance (very well balanced top-to-bottom) and to convey more detail and to be slightly more extended in the treble and with great bass definition, while still remaining musical to my ears in my system.
My impression is these also provide a stronger signal but with no increase in noise level.
In combination with the Grover SX speaker cables (with non-teflon dielectric and aluminum incorporated), I find the current Grover SX ICs to provide an excellent balance of detail and musicality and to be an excellent value. "

With further time using the IsoTek CD Enhancer disc and more listening to music time, I find the Grover SX w/ Al ICs and speaker cables to be very special indeed.
An added bonus to going with the Grovers over the JPS is being able to afford full multichannel IC set upgrade
and an Oppo BDP-83SE now at ModWright for "Full Multi-Channel Mod with Master Clock upgrade" (in process).
I feel that the Grover SX w/Al will allow me to hear the full potential of the new universal player upon its arrival...
