I have a pair of the original Celius 202's with the original tweeter and x-over since 2005 when I got them NIB for $900.
I've had lots of speakers - Advents, Cizek's, DCM Time Windows, Maggie MG-1, DQ-10's, Aerius, ML SL-3; and the Celius is better than all of them - modified. It's not as good as the Verity Parsifal (any generation) but the cost isn't close.
I'm talking easy mods:
Re-cap the xover - if you use moderately high end caps, the focus in th mids and highs jump.
Replace the thermistors (for protection) and replace with resistors of the same Resistance at room temp. It makes them sound much more coherent. Unless you are pumping them full of watts you don't need the protection (Pass X-150 driven to clip from time to time in my system with no ill effects.
Also put in a high pass cap for the tweeter - cuts high end hash to a large degree.
