Dynaudio Special One-Anyone heard/own these?

I'm new to Audiogon and really loving the wealth of experience and information!
I recently found a pair of Dynaudio "Special One" and other than the Dynaudio home page, there's very little info I can find. Has anyone heard or owned these? If so, what amplifiers did you like to power them?
I'm running them w/ Carver TFM-15cb 100w per channel,
and it runs hot compared to other speakers. I know the Dynes are 4 ohm,and 84 db sensitivity. Do I just need to get a monster power amp to light these up? (They do sound very,very good-but I don't think I'm really getting the full impact).
I'd be grateful for any suggestions you might have.
Thanks
