warm sounding cartridge for rega arm

Grados will likely hum as you get to the inner grooves. I tried a Grado on an AR table and couldn't take the hum. The Shure may fit your bill, but so may a Rega cartridge such as the Bias 2. I would pick the Bias

i assume that the stanton and rega cartridges meet my definition of warm. i am not looking for detail. i am looking for euphonic coloration.

when i called music direct, a salesman recommended a $299 soundsmith cartridge. i have no experience with any of the cartridges suggested so far, but i thank you for your input.

Well i can suggest the Ortofon 2m Black
Very nice cartidge !

Looking forward to trying an AT AV33PTGII on my RP6, which has been described as a great tracker with its fine line stylus and just a touch on the dark side of neutral.

Sumiko Pearl. With VTA set a little low, you'll get exactly the sound you describe, with excellent midrange resolution and solid tracking. With VTA set correctly the Pearl is warm-to-neutral--the treble roll-off is still there, but the mid-bass bump is reduced. When I say neutral I don't mean "bright" or "detailed"--I mean relaxed and musical, placing brass and wood and gut and human voices there in the room with you. I love the Pearl.

I just switched to the Pearl from the Shure M97XE. The Shure meets your "warm" requirements perfectly and tracks well, but build quality is poor. I bought two styli for it; both were badly misaligned. Also, the mounting block and cartridge body are two separate pieces _glued_ together--mine fell apart and had to be super-glued back together. My glue job held up better than Shure's. Now it lives in a drawer.

The Stanton 500 is wonderfully midrange-rich and involving but not the best tracker. I'd love to get one again to have as a backup cart.
