Let me suggest the Clear Audio Aurum Beta S MK 2. I have recently purchased this cartridge (actually its predecessor) and I am very impressed.
Best all-around cartridge for 500.00 new
I just purchased a Rega P25/RB600 and am shopping for a worthy cartridge. I listen to almost anything and spread my listening time among most genres about evenly. I've only got a few dollars left to spend and want to get the best all-around cartridge available. Any thoughts on the Grado Sonata or am I just asking for trouble with hum?
