Hello Ron,
I used them briefly with my Mephisto amp.
I had a chance to compare them with my Shunyata Alpha HC and Transparent MM2 power cords.
Silence: 1) Shunyata 2) Gryphon 3) Transparent
Focus: 1) Gryphon 2) Shunyata 3)Transparent
Body: 1) Transparent 2) Gryphon 3) Shunyata
Speed: 1) Gryphon 2) Shunyata 3) Transparent
Stage size & depth: 1) Transparent 2) Shunyata 3) Gryphon
Overall musicality: 1) Transparent 2) Gryphon 3) Shunyata
Detail: 1) Shunyata 2) Gryphon 3) Transparent
I chose Transparent at the end since musicality and emotional connection with the music is my priority. Now I have the new XL ower cords and they are much more detailed and focused than the previous version without losing its famous musicality.
Gryphon's VIP power cord is a nice cable but should not be bought without tying in your system. It has strange/unusual bass. It's deep but a little disconnected from mids and highs.
All of my findings are limited with my than system (magico q3, dcs, gryphon pandora & mephisto) and my ears.
Love and respect,
Cagdas
