MM Cartridge for music on the heavier side

For this tonearm and turntable look for Stanton 881s mkII or Pickering XSV-3000 cartridges with Stereohedron tip, within your budget you can find even unused samples probably. Another absolutely killer option for the money is Audio-Technica AT-ML150 OCC with MicroLine stylus.

read this article first.

For a better cartridges you will have to expand the budget for MM, each brand i have mentioned have higher models for higher prices, they are better, but what i recommended is already great! 

P.S. I have a pair of Sl1210mkII with all the mods (fluid dampers, isonoe footers, complete rewired etc), not in my main system, but i know this turntable very well. 

Look at the Nagaoka MP-150.
Fits your budget at a hair under $400 new and delivers everything you ask for and more.
Still my goto cartridge for rock even though I have much more expensive options in my drawer to choose from.
It is a new current cartridge and replacement styli are easy to come by and fairly inexpensive.
Although I must have 600 hours on mine and it shows virtually no wear so you should get a long life from it.
Good luck.

Great advise Chakster. Thank you.

Thanks Uberwaltz. Never heard of Nagaoka.  Will o some research  on it. 

Never heard of Nagaoka.

It is a lowish compliance cartridge with bonded elliptical tip, nothing special, you can look at the specs (the compliance is so low ). You will never get a proper frequency response and a nice low and high extensions with such stylus and cartridge. This is an entry level modern MM and the price is very high for such mediocre modern cartridge as Nagaoka MP-150 (i paid $60 for it and this is what it worth in my opinion).
Also the life span of the elliptical tip is much shorter compared to the most advanced profiles like Stanton/Pickering’s Stereohedron or Shibata, LineContact etc. In my opinion paying up to $400 for this Nagaoka is a nonsense when Stanton and Pickering available online even for lower price (normally $350) ! Just make sure the stylus is genuine, this is Pickering D3000 for XSV3000.

Here is more about Stereohedron stylus from the manual for my Stanton.

Simply search online for users feedbacks about Stanton and Pickering models, people who really understand what is a good cartridge sounds like are fans of Stanton/Pickering.

I am pretty much adore them, the only difference is that i prefer higher models like signature Stanton SC-100 WOS (specs here), Pickering XSV4500 and 7500. Those cartridges are truly amazing.

Also if you will loot at the Audio-Technica AT-ML150 OCC you will find not only superior cantilever (Gold-Plated Beryllium), but also absolutely amazing MicroLine stylus tip (it can be used for 1200 hrs ! ) and PC OCC coil wiring and connection pins.

In this situation, taking in count the prices, i think the Nagaoka MP-150 is definitely an outsider.

This is the reason why professionals prefer Stanton, Audio-Technica, Technics in this artricle. They are definitely have an ear to handle disc mastering process.
