Whats your budget for speakers?
Also, bring along a list of your CDs/DVDs that you know very well from a sound point of view and a note pad so you can take notes about the different speakers you'll want to audition. The notes should include likes, dislikes about each speaker. Make notes on how the bass, mids, and highs sound. Bass fast and tight or loose, flabby and 1 notish? How deep does it go? Mids sound life like? Male voices sound naturual or do they sound chesty and artificially bassy? Trebles nice and smooth with lots of detail ? Does the treble sound harsh, fatiguing or does it sound smooth and inviting? Little things like like this that you should note down.
Speakers too look at;
PSB, Paradigms, Def Techs, Energy, Totem, DynaAudio, Polk, Mirage, Athena's, Klipsch...
Let us know how you're making out.
