Cartridges

@OP,  the folks who put down the uni pivot is because it is too difficult for their level of mechanical knowledge to adjust it properly. I change carts back and forth often enough that I can get to fully satisfying results in an hour every time, any cart. Upgrade the cart, forget about those few hot stampers, you want every record to sound better.

I go with @dogberry 

There is magic in many LPs.   Get the cart.

@baylinor   Forget unipivots.  They offer nothing a properly supported arm cannot and will always be unstable.  I have tried them.  You cannot 'adjust' a flawed design.  What to 'adjust'?   It just hangs.

A good cartridge will improve all your records. So if you have lots of records, the answer is obvious.

Last night, i pulled my very nice-sounding ART-9 MC cart, and put my Acutex M320 III STR cartridge in.

I haven't listened to it lately, but after some adjustments with the settings on my Modwright SWP 9.0 Sig phono stage, I was amazed at hearing the best sounding music I've ever heard from my system. I don't know what I did differenly, but I was captivated by the extrordinarily great sound I was hearing.

I know you can spend any amount you want to on a cartridge, but my Acutex only cost me around $90 a few years ago, yet deliverers mind-blowing sound (to my ears), on my middle-of-the-road system, but whatever you do, enjoy the music!

What an arrogant statement.

Not in my case mate.

I have listened to VPi unipivots for 30 years, set up a few, along with many other unipivots - Hadcock, Mayware, Audiocraft, and many others - still own a Naim Aro.

It is the VPI unipivot that is the issue - it's not a great arm. It might meet your standards, it doesn't meet mine - and has nothing to do with set up. The Naim Aro or even an older Graham unipivot will leave it for dead.

Lunacy to put a $5-12k cartridge on an average performing tonearm. Yes, it will sound better, but upgrading the tt & arm for the same budget will yield much more.
