Cartridge recommendations


I am interested in upgrading the cartridge in my current basement system:
it includes a Rogue Audio Cronus integrated, Project Tube Box Se-II phono stage, a Project Debut turntable, a Denon 110 cartridge, and Dynaudio Focus 220 speakers. I am looking to upgrade the system primarily by changing the cartridge. I am looking for a bit warmer sound, and would consider a Grado, but I have some concerns about hum with the system. Any recommendations for a cartridge that would be $300 or less?

I second the Benz Micro wood cartridges, I have an LP which is a wonderfully neutral cartridge, but just on the warm side of neutral, as opposed to the Zyx Airy 3, I used before. Unfortunately, they seem very expensive in the US, compared with Europe.
Another thought is Koetsu. I used a Rosewood signature and now a second hand Onyx, both great cartridges. It is very hard to choose between the LP and Onyx, so I am keeping both, long term.
As Chadlesko says, do'nt be afraid of second hand. Retipping Benz's is fairly cheap, Koetsu's not, but you effectively get a new cartridge. As a cheaper option, try one of the smaller retipping companies. The Expert Stylus company in the UK, provides a first class, reliable service. They have been in business over 20 years and I have never heard a bad word about them. Recently retipped my 2nd hand Koetsu
Another good choice for tube phono like your is the Grado Statement Master 0.5mv
Great mids and a well balanced sound
I'm just selling one!
Thanks for the suggestions. The idea of a Grado is appealing, but I have some concerns about hum. Has anyone used a Grado with a Project Debut to know if that combination is associated with the dreaded "Grado hum"?
Considering your sonic priorities, equipment and budget, why restrict yourself to MC's? There are probably dozens of MM's that provide the sound you're after for less money, and with no Grado hum (or dance) issues. Why go looking for trouble at 2-3 times the cost?

Check out Raul's lengthy thread on MM vs. MC and ask the people there (including Raul, especially). I'll bet they'd have good recommendations.
Hey Droz............Are you hearing any significant difference between your Cronus' built-in phono stage and the Project Tube box ??? To my ears, the MM phono stage in the Cronus is really, really good, and works quite well with mid-priced MM cartridges. My Rega Exact 2 sound absolutely great with my Rega arm and table. In your price range and on your Project table, you might want to check out the Ortofon 2M series. I agree with Dougdeacon that a moving magnet is the way to go for you. Save the $$$ and buy more LP's !!
Good Luck, and Happy Listening !
