Unless you use a Rega cartridge, something might be off. I think if you had bought a Rega turntable with arm attached, this would not be an issue, but due to the variables of making, attaching and aligning carts, you will have to go through an initial set up. Man, I had to go almost retail for my arm, because of my "newbeism" when it came to different arms and cartridges. The distributor took a good 1-2 hours getting the arm with place back on a hole for the same brand of arm, getting it aligned and everything else. The tools he had used, cartridge weight, alignment disc, leveling bubbles etc...and the basic setting up of weights for anti skating was nothing to sneer at.
No Randy, you are not being anal. Perhaps, you may better call it "sensible."
