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?

Try contacting Clearaudio directly or call Bes at Music Direct. I had a brief conversation with him about these cartridges as i too was somewhat interested in them. From what he described them as sounding like ( nothing like the stereophile review and recommendation ), i decided to leave well enough alone.

Music Direct supposedly has a new "demo room" now with a small selection of the electronics that they carry set up. I'm going to have to stop by there sometime soon and see what's new and exciting. They are about a 1/2 hour drive from me, which is pretty convenient to say the least. Sean

I have a used (200 hours) Grado The Reference ($1200 new - $500 used), and it sounds fabulous with my Rega P25/R600. I have not had ANY problems with hum, and it seems to be a good fit without needing VTA tweaks.
Allison2, I know it may be pushing your budget, but for $650 you can get a Shelter 501 MkII, which is a substantially better cartridge than any of the ones listed above, and indeed competes with cartridges costing $2-3k. If that is a little too far out of your budget, the Denon DL-103 or DL-103 Pro is a good second choice.
