The Sigma XC at about half the cost of the Omega works very well with the Everest. Also my 6000T benefited from Shunyata's better PC'stoo.
I’m a fan of Shunyata and my system is powered by their products. But an $8k power conditioner that needs a $7k power cord to function well, makes me question if the Everest is really my next step...
Doesn't get much better than that. Job well done. DIY can be very rewarding (sometimes not). Plus you learn a lot and have fun doing it.
