I have a Pro-Ject Debut Carbon turntable. It is fitted with a factory-installed Ortofon 2M Red MM cartridge. I find that even though I have an all tube system, the cartridge lacks warmth and seems bright, if not etched at high frequencies. I really don't like listening to it at all. Is there a cartridge in the $300 to $400 range that would provide a more pleasant listening experience that I could fit to the tone arm on this turntable. I'm not sure that upgrading to another Ortofon is the path to go here; I think some other brand of cartridge is probably what I need to try.
