Linn or rega


I have a 1980s Linn LP12/ittok with valhalla and sumiko BPS. Sounds cozy and nice but I would like a bit more clarity without losing the analog glow.Would a rega P9 with RB 900 be a good upgrade or should I get the cirkus upgrade to the Linn.
BTW I am looking to replace the cartridge as I find it thin and bass shy..

Many thanks to everyone who posted a reply.These were helpful comments.I think I will stay with the Linn.
I recently got a new Rega P9 with RB1000 tonearm, and it is an amazing table tonearm combo.

Ya... Look at me, I got a Linn and I hardly have time to post to Audiogon anymore!! I cannot stop listening to that darn thing! It's great!
I had a Spectral MCR cartridge on my Linn LP12 which was a kickass rock cartridge. After many years with the Linn I was going to sell it. I brought it to a Linn dealer for a pre-sale tuneup. When it was done we did an A/B to a new full-blown Linn deck with Arkiv....I liked my Spectral better. Until they put a Lyra Helikon SL on my "old" deck and it was awesome! I bought it and staying with the "old" table.
Yes, stay with the Linn, but please get a different cartridge! There are several MM and MC cartridges that will work better than the Sumiko.

Twl, I know, likes Denon, while others report excellent results with some of the Dynavector line.
