Had a pair of A-50v's bridged and driving Eidolons and felt it was a beautiful synergy. The Eidolons like power, and the 50's never even blinked, even at high spls'. Auditioned the Lamms driving a pair of Kharma Exquisites 1-b's, and that too was wonderful. Thought the nod went to the 50's as far as bass and dynamics and overall musical involvement, but this must tempered with the fact that the speakers were different.
