I want more from my Rega P5

The Shelter 301/501 will mate better with the P-75.Use the "enhanced " with these cartridges.The upgrades on the Rega will also help,along with proper footers under the table.

First I would make sure your set-up is correct.... Is the 'table level? Do you have the cart aligned properly? How is the VTA? (you would have to add shims, or some other after market (Teres) fix if it's not).

If all this checks out OK, then start changing things around... I have never been a big fan of the Rega sound, but you should be able to blow away most digital front ends with your rig.

I think one of the first equipment changes I would look for is to get some tubes into the mix. Depending on your budget there are some nice used phono preamps out there for 1-2K. Something like the ARC PH models, Conrad Johnson, etc.

it makes a significant difference. The P5, without the PSU, sounds closer to a P3.

Have to agree that with the comment that the Dynavector 10x5 and P75 combination is a little lackluster. Used both with a Nottingham Spacedeck. I preferred a more dynamic stage (a Plinius Jarrah)with the 10X5. In your case, a good low output MC (Denon, Dyna, Lyra, Shelter etc) will probably be a good move. The denon carts would be an inexpensive option.

Don't waste more of your money--it's upgrade time...
