The HD800's bass is one of its best qualities IMO. It's subterranean and hits hard when called upon - and it's fast, nuanced and distinct instead of smeared, lumbering flab.
The HD650 doesn't dig as deep and its low end is characterised by that mid bass bloom but there is still good presence in that region. Through my system it's bass is taut and textured.
Have you heard the Senns through this system?
