Wow, this is kinda like (fun) work! I've spent about 20 hours over the past 4 days listening and reconfiguring my system to test out the ZenWave power products:
1 Surge-X with a PL11 power cord
1 PL11 with very pretty Furutek carbon fiber Rhodium-plated connectors
1 PL14 with solid and serviceable copper Neotech connectors
I'll jump to the conclusion--while I didn't have any epiphanies, the Surge-x is transparent, and did nothing negative, which given it's protection value, is a good thing. The PL11 power cord did change the sound ever so slightly, which surprised me as a power cord skeptic. Both the power cords and Surge-X could have a bigger positive impact in a different setting. The quality, fit and finish is outstanding, and I love the look of the Furutech carbon fiber connectors.
My system is described here:
SystemFor the test I used my fall-back evaluation music:
1) Bela Fleck Live Art: Improv/Amazing Grace and Shoobee's Doobie (for audience ambience, bass slam and attack, PRAT)
2) The ARC Choir Walk with Me: Shady Green Pastures and Walk With Me (for male and female vocal timbre, air, ambience, and imaging)
3) John Rutter Requiem: Praise Ye the Lord, The Lord is my Light and Salvation, and Out of the Deep (for sibilance, male and female vocal timbre, air, ambience, bass, clarinet, cello, and violin timbre
4) Miles Davis Kind of Blue: So What (for horn timbre, drum kit reality and sibilance, emotion)
I also did some casual listening to some Jethro Tull Aqualung, The Who Quadrophenia, Delirium Poem, etc.
Surge-X: For the test I removed both Richard Grey Power Stations. The Surge-X was plugged into the 20A dedicated circuit via my DIY 9ga silver-plated copper quad hospital outlet. I tried different combinations of amps and subwoofers into both the quad outlet and Surge-X with no audible difference, which tells me the Surge-X provides plenty of juice. I left one amp plugged into the Surge-X for the remainder of the testing. I did not hear any difference between the Surge-X and Richard Grey Power Stations in any of the tests I ran.
PL-11 with Furutech Rhodium connectors: I did seem to hear slightly more detail with this power cord when plugged into my Oppo 105 CD player than with my reference DIY cord, and perhaps a bit less grunge. I didn't hear any difference on my pre-amp compared to its stock cord.
PL-14 with Neotech connectors: I did not hear a difference on either the CD player or pre-amp with this cord.
Thanks to Dave for the opportunity to try out this gear.
