You know I recently saw Frank Shroeder observe that the “two best cartridges in the World” were the Denon 103R and the Audiotechnica AT95 – both inexpensive, practical cartridges. I listened to both on YouTube and in A:B comparisons, they each sounded about the same as cartridges costing many, many times more.
I listened to the A:B comparison between the Denon 103R to the expensive Lyra Delos and could hardly tell a difference between them. It's a bit surprising how subtle the differences are between many cartridges, including some of the most expensive ones.
So... I'm going to start out with the Denon 103R, and maybe the AT95. I may never need to go any further. They both sound superb.
And... as a few have suggested, I will likely begin with setting up my Linn Sondek again and trying the Denon 103R, before "I plunge into deeper waters."
