Cartridge recommedation needed for old table/arm

I'm asking advice for new cartridge for a 20 year old set up: Signet XK50 tonearm on Denon DP 1000 table.

I use to have a Dynavector Karat low output MC with Ruby cantilever mounted on the XK50. The DV cartridge was latter replaced by a Adcom crosscoil hi output MC cartridge but I remember liking the detail and smoothness of the DV better. I haven't used the table in about 10 years but I want to get back into vinyl and figured I'd start by mounting a new cartridge on the Signet/Denon combo and buying a new phono preamp. Also, I would probably buy a new phono cable with DIN connector.

If it makes sense to mount a really good cartridge on this Signet/Denon setup what would you recommend buying new today? Would you spend up to $1,000 on this old setup like a Lyra Lydian Beta? Is it worthwhile to invest big dollars in this old setup or just put a $300 cartridge on it and spend the money latter on a completly new table/arm/cartridge setup? I could always put the Denon/Signet table in a second system and wait and purchase something like a VPI Scout/Lyra Lydian Beta combo when the funds are available.

Here's the specifications from the original owner's manual I was just able to locate in my attic:

XK50:

Dynavector DV/Karat (I don't have anymore but I thought knowing the specs on it may help in recommending something new)

The rest of my system is as follows (all purchased in the last 20 months)

Electronics

So do I put a new cartidge on the old setup and try to work it in to my current system or relegate it to a 2nd system and wait to put the big dollars into something new?

Thanks.
