I found myself entirely too busy at work to listen to my hi-fi rig at home and ended up taking a 4 week break. Upon return I simplified back to the 400i, BUDU, and Bifrost and once again am very pleased with the fidelity coming from this setup. If you are looking for and end-game setup, and a BUDA cannot be found, the Magni 2 Uber will suffice.
If you can return to your rig day after day and never find faults with it you probably have something special.
Another excellent setup is the Bifrost, Mjolnir 2, and the Audeze XC with microsuede pads.This combo offers a soft yet detailed treble, smooth midrange, and clear and defined bass without sounding boomy.
