Does Gryphon Diablo 300 Benefit With A Costly Mains Power Cable?

@ryder I reduced the cost of my Dragons by purchasing one metre lengths. I paid no more than $3500 to $4000 each for them, from a dealer.

Audioquest 230v and 120v cables are not interchangeable, regardless of plugs.

My Diablo 300 is powered by a Synergistic Research Atmosphere X HC (L3) powerchord with excellent results .  I have used Audience AU24, Audio Quest (not the Dragon…), as well as others.   The SR pairing led me to change my system to a complete loom of SR Atmosphere X Euphoria cables and power conditioning.  Not sure brighter is something you will achieve with the Diablo 300 as I don't believe it is in it’s DNA but a dynamic very large three dimensional soundstage with excellent and engaging detail are all present in my room.  

I’m an owner of a Gryphon Diablo 300 and when I replace the power Cord the on the Gryphon the sound difference between a DIY power cord that I have and the Nordost Heimdall 2 was noticeable in favor of the Nordost. Maybe this may help.

Congrats, the Diablo300 is fantastic, one of the best sounding amps that I have ever heard. 

I have tried a few PCs with it and to me, they all make some level of sonic difference.  In the end, I liked the Audience front row best. The hurricane aq was powerful but a little mushy on highs, the Elrod golden signature was good - kind of an inside out sound - but rounded the highs and bass, while the Audience was just right. 

Regardless of the naysayers that exist, trust your ears and see what you like best!

Tip - the 300 benefitted from some isolation feet in my system, so dont be afraid to try those as well.

Happy listening!

An old SR A/C Master Coupler improved dynamics on my Diablo 300. The swedish Gryphon distributor uses Nordost PCs.
