The description of what you would like sounds alot like the Thiel 2.4s. Are you sure that these were properly broken-in, set-up, and system matched when you listened to them? If they sounded dark, then perhaps a change in the CD player or amplifier would remedy the situation. I think that out of the speakers you listened to, the Thiels outclass the rest. You might also want to listen to Avalon, although I think the Thiels are a better value for the money.
