Mod my Rega P5 OR...time to move on ??

I'm not sure you will notice as much of a difference moving up the Rega line as going to a heavy platter design. Maybe just stick with what you have unless you are finding a particular parameter lacking. 

As a budget alternative I have used ZYX carts in Jelco 750 tonearm and the carts work quite well with the heavier arm.

scm-2 listings that can still be negotiated for less.
The Classic is about double the cost of more mods, and itsa NEW table, clearly superior in build. Since sonics are subjective, just how much "better" it is than the P5?

For a little more, the Prime will have the nicer arm and VTAon the fly.

I will say the modded P5 is reasonably close to the Calssic,but the stock Classic is closer to an uber table more,then any modded P5 will ever be.

Youre treading dangerous waters $$$ dumping more money into that P5

Willie---you can read all about the Audiomods arms on the company's website. They are made by hand by a master machinist, who uses only the latest Rega arm tube, all other parts machined by him in his shop. The design is his own, and contains a lot of unique ideas. A lot of arm for the money.

@bdp24 - apologies - I misread your post. I read it as saying the VPI arms were very different.

I have the Audiomods Classic, so I know about them.

From what I have read the compliance between the two brands is different.

Apologies for the confusion - cheers
