speakers first (naturally). but if rock/pop is what you love the most, maybe not. the recordings aren't that good (for the most part) anyway.
but if you LOVE Blue-Note jazz, or string quartets, etc. then yes, that's a good place to start. Try listening to Eggleston Andra speakers (ver.1, 2, or 3) or similar speakers (Joseph Audio, Aerial Acoustics, B&W, many others) and hear much more going on as well as a better integration between the different drivers. If you have the space and DON'T need POW-POW (dynamics), Magniplanars are ridiculously good speakers.
