Don't forget the basics

I dug out of my LP collection a Shure "Audio Obstacle Course - Era III" that I may have gotten through a Stereo Review offer around 1973. It's to test the trackability of your cartridge by showcasing some difficult-to-track passages at increasingly loud volumes. But at the beginning of the disc, they had some basic passages to adjust balance, etc. One was to see whether your speakers are out-of-phase, and it turned out mine were. A quick switching of the wires on one speaker made a tremendous difference in the sound of my system. I mention this because I only played the LP on a lark, and it returned something of real value.

I have a copy of that LP and still use it when I take my gear apart and have to set it up again.

I have the Shure V-15 Type V Audio Obstacle Course LP. Sounds like it is slightly different than the ones you have. I don't have a Shure cartridge; does that make a difference? I suppose I should give it a try in any case.
