Get the Cullen mods if it's stock.But if one has the dough going to Rhea or Ear432 no comparison.One thing that my friend likes with his .23Mv Dynvaector is that he has dual volume control on unit.Not sure he'd be so happy with that cart and 89 db speakers if he didn't have Cary Sli80.Also when you compare gain section of cheaper op amps in GCPH versus better circuitry in pre or integrated thjat would be A/B.Sure purity counts but I have gone passive route for same end and didn't get dynamics or bass.And there is quality difference in same.
