"Too much Stokowski."Sergei Rachmaninoff in 1940, reacting to a demonstration of a stereo recording of Leopold Stokowski conducting the Philadelphia Orchestra
I don't remember when, but at some point during the past few years I realized that, in my home, mono cartridges outnumber their stereo counterparts. A few weeks ago, my collection of phono equipment took another step in the same strange direction: After receiving from Ortofon a sample of their CG 25 DI Mk.II mono pickup head ($902) for review, I was so impressed with its sound that I asked if I could buy the review sample. Now, having put check in mail, I own twice as many mono cartridges as stereo ones. Take that, multichannelism.
