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

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.

I had a couple of Benz Gliders a few years back, one a mid output, the other low output. Both rocked well on Zep Sabbath, Blue Oyster Cult etc, but I had them tracking at max VTF. My current favorite is Lyra and they make the Dorian that fits your price range.

What arm are you using with the Shelter?

An alternative to the Dyna 17D3 is the 20XL, which is a real bargain at its price.
