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.
