Best Cartridge for Less than $500


I have a SOTA Comet turntable with a Rega 300 tonearm and a Grado Gold cartridge. I would like to upgrade my cartridge and am looking for recommendations. My budget is $500. (The rest of my setup includes a Dynavector P75 phono-preamp and Aragon 8008BB power amp.)

Thanks.

BTW my dad has the ACE and I think it is warm, mushy and pretty boring.......it sounds fine but never thrills, it is way too polite.

Great cartridge for the $$
By the way Adidio, there is a new ACE in town, which I have not heard. Benz just released new versions of their micro line - The "S" series. The prices went up...so the ACE is now $700. If you could find an old benz cartridge to trade in that would get the price closer to $500.

Here's the link to the news on their websight:

If I had to choose the sound character of the ACE - I would choose Warm over lean, so I could see how Chadnliz might think that is sounds "warm, mushy and pretty boring". I am guessing that Chadnliz probably likes a more sparkley and lean sound. I would never say that it sounds mushy and boring. Warm...yes, probably more on the warm side than the cool side. That's why I was so surprised by Audiofiel's statement that the cartridge was lean and harsh.

Be careful what you match it with. I will say that I pared my ACE with a warm "Polite" integrated (Magnum IA170) and it does make the sound to warm and fuzzy for my tastes. I am in the process of upgrading everything and I will definitely be looking for a new amplifier.

As you can see, everyone has an opinion. A lot depends on how the cartridge is set up. A lot has to do with what components it is mated with. Anyway, good luck with your venture and let us know what you decide.
