"Good" is relative. No two sets of ears are the same. The point of this addiction is to please your own ears.
As stated above, playing around with speaker positioning can make a HUGE difference. Start there. If after some experimenting you still aren't satisfied with the results, go for an amp change. The Adcom 555 or 555 mkII are great amps for the type of music you listen to. Plus, you won't find any lacking in the bottom end. The 555s have plenty of slam factor and can be picked up used quite reasonably.
