A mono cartridge doesn't have as many issues to deal with when mounting compared to a stereo cartridge.
But do you still worry about setting it up for two null points? Azimuth isn't much of a factor, is it?
A friend pretty much destroyed his Benz Ace, and had it made into a mono. He's loaned it to me since I have a sizeable mono collection and he has none. Between how it sits and my increasingly bad eyes, I was having to guess a lot when installing it. (By the way, it actually sounds pretty darn good, and I may make him an offer on it)
I know Charles has a mono set up. Anyone else around here? Is there a go to guide for mounting mono?
