Cartridge for Rega Planar 3 / RB300

I'd like to set up my analog table so I can enjoy some old vinyl again and thought I'd ask for suggestions. The cartridge I have on the table is an older Supex 900 Super with an in-line (read el-cheapo) step-up pre-amp.

Since I've been out of the loop for awhile, I thought I'd ask the collective conciousness. I listen to acoustic/folk, jazz, and classical music primarily.

If the suggested cartridge requires a step-up to line-level, I'd also be interested in hearing recommendations for a new phono pre-amp. BTW, I've heard good things about this Lehmann Black Cube (with the upgraded power supply) wondering what the local wisdom is on these?.

I've considered replacing/upgrading the table, but I think for now, my table has a great deal of potential if partnered with the right cartridge and pre-amp. Any help would be most appreciated. I'm trying to keep my budget under 1k for the cartdrige and preamp.

Downstream components are a Levinson 380, 332, and B&W 802 Matrix III speakers.

Thanks in advance,

Alan
