I've been offered Arcs and Discoverys, anybody any opinion on how good these are cheers?

What about Revel Ultima Gems, does anybody have or has had a pair of these in the past thanks?

Heard Revel Ultima Gems years ago at a dealer in the US. Sounded reasonably good driven by ML integrated but I can't remember much of the details. Nice looking speaker. Think there's a pair available on the Wam or PFM
