Recommend cartridge for JVC QL-Y66F

I was lucky enough to find this gem in Craigslist over a year ago, in mint condition. The TT has an AT 142L cartridge which is not bad but I would like to get something better. I tried an Ortofon 2M Blue and even though it is a good cartridge I sold it as I thought it was a tiny bit hard. Any recommendations up to $400? That's way more than I paid for the TT, but again, it is in great shape.
The DV 10x5 is a great all around cart for the money. Its high output so you can use it with a MM phono stage.
I have a slightly older brother to the QL-Y66F, Mine is a QL-Y5F. It has a similar ED tonearm, S shaped rather than straight as in yours but both support medium mass cartridges. I had a Denon DL-110 and it's a great sub $200 cart for it but I recently bought the high value Shure M-97xe and my purpose will be to buy the Jico SAS stylus for it. However even the stock Shure stylus works great with this arm.
