The best I heard was on my Ikeda 407 for the 103r. It did sound surprisingly decent. And I’m sure other expensive high mass arms are nice to. But I would never restrict my expensive arm to a cheap cartridge. With my FR64fx and Basis vector the denon wasn’t as smooth or refined sounding. As someone stated already, the 103d, I had one in the 80’s and really liked it. I can’t remember the arm, it was not an expensive arm and was lower mass. It was on an Ariston table, similar to the Linn Sondek. This would be a better choice. Buying a 103 in my opinion is for budget reasons so the arm is going to be budget too or just get a better cartridge. I get the whole idea with getting a cheap cartridge to sound good is fun but there not so cheap anymore. I bought 2 about 5 years ago for $275 each including shipping. Quite a bit more pricey now. Still have one with about 15 hours on it. I find for a single cartridge owner it’s too expensive to get these to perform good that there’s better choices to be made.
