I don't know about anyone else, but if I didn't have a cartridge that didn't play Reggae as well as classical, blues, operatic, jazz or pop-pap, then I wouldn't entertain having it in my system because a good cartridge should be well capable of 20Hz-20KHz, with dynamics, trackability and resolution enough to do all musical genres justice. The Zyx can and so could the Shelter in my system before that. Now if we're talking about loudspeakers, then that's a different story. Few I listen to can do all music the justice it deserves. For me, a do-it-all speaker has to (by definition) be capable of full range performance, have adequate resolution and measure reasonably flat with good driver integration and phase response. That rules out around half the speakers sold today. Since not everyone has the room (or budget) for a good full range speaker, then taht is really where most compromises lay, and I go along with Jerry here on the speaker front since some are better at some genres than others. That, or we learn to set compromises we can live with.
