Rega planar 3 upgrade


Hi,
I'm looking to upgrade my 30 years old Rega  planar 3.  I have the motor upgrade from Rega installed.
I have a Linn Linto Phonostage with a Ortofon Rondo Red MC cartridge (which I hate...too bright for me).
I have thoughts of switching to the Rega Ania pro MC cartridge and maybe replacing the cable of the RB300 tonearm (30 years ago the RB300 came with a very poor quality cable).
1. Any thought on the Ania pro ?  Would it fit the Linn Linto ?
2. What cable can I use to upgrade the RB300 ? Can I use an old XLO Reference 3 RCA cable that I have, strip its edge and mount it to the RB300 ?

I have the P8/Ania...

I compared it to the P6/Ania and I was surprised on the difference in sound.  P8 was quieter and the dynamics was  greater than the difference between the P3 and the P6.

I use my McIntosh C2600 preamp's built in phono stage.

Fuel for thought - I planned for future upgrades to be the cartridge/phono stage.  
I just purchased the Rega Planar 8.
Assuming I have Linn Linto as phonostage, what do you think would be the best value for money cartridge ? Ania pro or Apheta ?
I totally agree guys. You convinced me. After 30 years...its time to let go.
It reminds me a restoration I did to a Suzuki GSX750ES 1985. I gave it my heart but eventually it remained a beautiful but old antique, with a fraction of the fun of a new motorcycle.

The question is now : P6/Ania-Pro or P8/Apheta ?
Seems like Rega P3 owners have been getting the itch lately....

I'd spend the extra cash for the P8 and Apheta, since you're a long hauler
Good for the next  30 years.

Consider upping the phono stage afterwards.

At that price WITH excellent cart, forget the P6 
I think you would be better served exploring the Planar 6 - the table itself is a significant improvement that you would hear the difference using the same cartridge on the Planar 3.
Think of saving up for a Rega Planer 6. YOLO!
I had a Linto on loan once and it was okay. Very tight and a little dry. The basic Croft Micro tube phono amp was more lively and transparent. There is so much more you can do.
