Please,reccomend "rock" cart. for under 1K

I know it might sound like hyperbole by now, but Zyx cartridges are extremely dynamic, especially in the bass. In this regard, it is leaps beyond anything I've ever had.

I second the Dynavector 17D III. Recently installed it on my Lenco/Rega and it is excellent throughout the the freqs. Beware that it is a tad finnicky to set up. The "cantilever" is unusually short and part of the stylus itself. It barely clears the surface of the LP so VTA is critical.
I have had very good results with the Deonon 103 and they are cheap.

Shelters are good rock and roll cartridges.

Even their top models do not offer the delicacy, finesse, and sophistication of the better moving coils but they do rock and roll quite well.

A Decca Super Gold, about $1,100.00. Big Fat P-R-A-T. Amazing extended mid and low bass. Drums and cymbals sound extremely life-like. Huge 3-D soundstage. Digs deep into the grooves uncovering detail you didn't know was there. It will get your pulse racing.It loves UK rock pressings. Has a very very high output, 5mV. I had to have the output changed(lowered) in my Audio Research Phono Pre to accommodate this puppy, but it was well worth it. It rocks yet does all the other music as well.
Whatever you get do, take your time and do your research. Google and lurk the forums. There are always less expensive options such as MM's.
Luck!

I have used the 17D3 (what i am using currently) as well as the DL103R and plain DL103...I would suggest that for rock n' roll the 103R may be right up your alley - it has great presence and dynamics. it will also allow you to save a few bucks for more LP's!
I must add that the Dynavector is quite hard to beat at its' price point, and fits for all types of music.
