Upgrades or a different table?

If you listen to classical music, speed stability and striking 33.3 rmp is most important. Look to the classic Japanese DD of the late 70s 80s. If you can afford new prices, look at Brinkman.

When using older TTs with rubber mats, replace them with a product from TTWeights or the like. The compliant rubber creates small flex and lost music retrieval.

I am not familiar with your cartridge. However, a Denon DL-S1 is a very fine choice at a reasonable price (Comet Supply or Galen Carol).

I would replace the Phono asap

Phono preamp is always a good move. I haven't heard the PS audio it may be a good unit. If it were me I would put an Audiomods classic arm on the Rega. This will be a substantial improvement since you plan on keeping the Rega.

What phono are you guys suggesting as a keeper, considering the rest of my setup.
I think i can do better in analog with upgrades on my p5, i appreciate so much your time helping me with this.
The cart is brand new, i guess i have to sell the ps audio and get a different one but so many to choose from!
Regards

I had owned a blown out totally upgraded P5 for 3 years.
GT Su-platter, GT Delrin, Michell Technoweights, Dual White belts on Lim dual pulley, TTPS, Dyna 10X5, Limm feet etc.
it was excellent!

I wanted to change (nuts) so I sold it as is. The buyer got one hell of a deal and a superb sounding P5.You don't see very many around this upgraded being sold.

I would not do the upgrades unless you were planning on keeping the table for some time. You will not recoup the $900+ as I had invested unless you sell these parts separate and you will not get it back either way.

With all that I have since purchased something else that surpasses the upgraded P5.

Simple, if it is a keeper upgrade.
