i heard the $30K Edge monoblocks at CES and was mighty impressed. they rivaled the Halcro as my favorite solid state amp and would probably be the ss amp i would buy for ease and musicality.
i do prefer the Tenor OTLs that i have but the Edge made beautiful music; piano, violin and vocals sounded real and natural to a degree i have not heard on solid state previously. i am not enamored with the case-work or the fact they are not balanced.....but they delivered the sonic goods.
i did not hear the less expensive Edge amps so i can't comment on those.
