It was not a reasonable or genuine 'audition:' when I heard the M5 it was with a music server unfamiliar to me. Nonetheless, they did not sound as sweet, in a musical way, as the V2.
The M5 may be able to handle greater volume of music, namely operatic scale performance and complex symphonic passages, or fill a larger listening space but I generally listen to smaller scale music.
For that type of playback, the V2 speaker, on first and careful listening, was stellar. When I've heard them again, compared directly with Verity Parsifal Ovation IIs I will comment again. It should be a reasonable comparison, as it will be in the same room with the same electronics and cabling. More to come.
