As this is your first jump into "higher end" (really can't call this high end as it is more mid-fi which is where 99.5% of us fall) I highly encourage you to head out and listen to as much music on as many speakers as possible. Go listen to some B&W's, Paradigm, Energy, PSB, Monitor Audio, ProAc, Kef, Vandersteen, Von Schweikert, Aerial Acoustic, and the list goes on. If you are anything like me this is what you will find most enjoyable! Once you have what is is you were seeking, you will want to do it again and you may also come across a great dealer. This contributes a lot to the upgrade bug.
There are many that do love the sound of these speakers (myself included), but you are not everybody! Your ears will be different and this is why I encourage you to pack up your fav studio discs (little jazz, good female vocals, blues, and some classical) and head out to Almas, Audio Video Alternatives, Audio Dimensions, Gramaphone, and every other local mid-fi/high end place you can find (there are many around). If you have any questions, I've been to them all more than once.
