Opinions greatly appreciated

Hello All,

I just recently purchased a creek obh 9 mc phono stage at my dads request for his turntable assembly. To his mistake he found out his shure v15 IV is a mm phono cartridge. He finds the sound bad which is no suprise. He is considering possibly replacing the cartridge or just selling the phono stage for the creek obh 8. Does anyone think it would be worthwhile or even possible to find a MC cartridge of better quality than the shure v15 IV for $75-$150 new. Or would it just be better to just get the mm phonostage.

Thanks in advance
