I only voice concerns based upon trying to give conservative advise. I have heard of the Nottingham Space Arm, WB arms, and Graham 2.2 giving what the owners called good results with the 501. It is possible that your arm may work well also. I'm not sure.
My concerns, as stated in the past, regard not whether it will play in the arm, but how close to optimum it will be. This is something that you will have to decide for yourself. If you feel that it works well, please pass the information on to us, so that we can have some good user info to work with on future questions.
My general advise is to buy a tonearm with the cartridges that you plan to use, in mind. Then you don't get caught in a position where you already have Tonearm X, and then hope that it matches with Cartridge Y.
If the 501 works well for you in that arm, you are in for a treat, because the 501 is a really nice cartridge.
