Hi macbob! As luck would have it, since I received the cables, I've been travelling. Hence, I haven't had that much time with the DHC Molecue SE Fusion. The Fusion is a 3 wire hybrid of silver and copper.
My initial impressions are that it clarifies the sound from the 812. That would be from the silver component of the hybrid cable. It is early days still. But in some recordings, the 812 seems to come off sounding a bit lean. Don't get me wrong: it's still good, but it seems to be that the brightness seems to take away some of the more organic bass decay that I love about the 812. I'll come back again with more once I have received the Toxic Cables Black Widow that was done for me - the difference here is the litz copper will give warmth, body and a more organic sound. And the 4 wire configuration will likely give more details because of greater conduits to convey the information from my amp. This DHC Fusion still needs more burning in, I suspect. Let's see what happens.
