Hello Olddude55, I have read that you are using a herbie's mat excellent eay on a Dual 1219. I have the same turntable and I was considering the same mat as alternative to the stock one to replace the lack of an adjustable tonearm height, but I was hoping to hear an improvement in sound, did you heard something like that or nothing at all?
Thank you in advance for your attention.
