Da FUCK? I'd rather listen, with bare ears, to myself take an angle grinder to the inside of a rusty fuel drum with AOD's generator providing power. To each his own, tho'.
I found an old Krokus cassette awhile back, and went out to the shed where the only device I still have that can play it is located. Jeeeeeezus did they suck!
Must be your cassette version that is making it sound bad, as all my CD's of Krokus sound stellar !!!
