Thanks @clio09. I don’t know what Cervantes looks like, but I may have met him at one of the appearances Roger made at Brooks Berdan’s shop. He did one for the introduction of the RM-10, which I attended. I was putting together a pair of stacked Quads, and asked Roger if he recommended a single RM-9 to power them, or a pair of RM-10’s, one for each pair. He answered an RM-9, and I countered with questions challenging that opinion (how impudent ;-). The next time he was at the shop he told me he had been reconsidering the points I had made in favour of the RM-10’s, and had changed his mind, the RM-10’s were now his recommendation.
I ended up going instead for a pair of Atma-Sphere M60’s, but now have a single RM-10 on a single pair of Quads, a marriage made in Heaven, where both Brooks and Roger are now listening to Angels sing.
