new Cartridge for Rega P1

New speakers have really revealed some deficiencies in my vinyl listening. Records sound muddy and boxy compared to CD’s. I’m after a more bright mid and highs. I also get some IGD. My TT/cartridge is about 13 years old.

My setup is Rega P1 w Elyse (purple), NAD PP1, Marantz 5009, NAD CD, ascend sierra 2 & rythmic F12 sub.

Budget is < 250. Pref ~100. Based on other threads, I’ve been considering Rega Bias2 or Elyse 2, Ortophon Red&Blue, Nagaoka MP 110. Probably the Nagoaka is of the most interest although the rega cartridges would be easier to install.

I’d probably install it myself. So I’d like to avoid anything where I need spacers.  But I've done it before.

Any recs?

Thx!!
