I have to agree with Heinz here. I tried this song with the Mysphere 3.2 on the WA11, the Nagra Classic INT and a Luxman p1u. In all three cases, I found no issues with the bass at about 100db ear point. Bass is restrained but I cannot hear any distortion against the 1266 phi with the same material. As far as I can tell sub-bass is about 4-5 db off from the 1266 phi, but that's to be expected given the 3.2's design.
