Well, thank you, I will think it over ....I have such excellent cartridges with original needles as Victor x-1/II, pioneer pc-600, shure V-15III, AT 150MLC, sony XL-45, all MM, and only one but very excellent victor mc-5E (MC),
I wonder is Grace F9 U at the same level, and will I hear more wor different of what I hear already with what I have?
Is Your Ruby Grace F9 your best cartridge and what you compare it with?
