The 8005 has a killer phono section and is a wonderful amp. We love our 8004; however, for you it might be more of a different flavor than a large step up. Your MF is no slouch.
If you're itching to play with tubes and want to take a true step up, I would skip the Sphinx and go straight to the Rogue Cronus Magnum II, new or used. Several Triton Two and Three owners are using it to good effect. There's also a good review of it on Enjoy The Music that paired it with the Triton Three.
