vonhelmholtz - Thank you for your insight into Shunyata's power conditioning options. Unfortunately I'm currently not able to pursue a high quality power conditioner at this time. I agree with you completely that cables matter, all cables.
I've explored upgraded recepticals and I recently used the Furutech GTX-D Gold. I found it was lacking in low frequencies and momentum. I've also considered the Shunyata outlet however I'm currently using the AV Options Deep-Cryo Hubble outlet. It works well with Naim equipment. It has much better dynamics and low frequency extension than the Furutech GTX-D Gold so for now I'm satisfied with the Hubble's performance. Today the X EF power cable is sounding very musical with greater resolution than my previous cable. The pace and clarity is very good today. Musical instruments sound more authentic than with my previous cable.
My intention is to keep listening to the new X EF for at least thirty days to get a full understanding of it's potential. If I decided to keep the cable it will continue powering the Naim Supernait 3. My intention is to consider another X EF for my Naim nDAC's Digital section and a Shunyata Venom V10 NR to power the Teddy XPS power supply that's powering the Analog section of the DAC.
