If you read the Stratus and Stellaris threads, you will realize that these are HD 800 amps. Even the Super Dupont mod inventor is a Stratus owner and thread poster. If you want to see a beautiful headphone amp, Go to Donald North Audio website. I have 10 more months to wait for my Stratus. Meanwhile I have my Cavalli LC 2.0 and Ragg to entertain me.
