Feickert blackbird, kuzma 4 point which cartridge

İ am planning to buy a new cartridge for feickert blackbird tt, kuzma4 point tonearm, full asr electronics. İ have budget around 5k. Lyra, koetsu, shelter, dynavector, zyx, miyajima, ortofon are very popular i think. İ never had a chance to listen except ortofon models. Reviews are very confusing. İ really like to hear your opinions about these manufacturer models, and your recommendations.
