Upgrade suggestions

Over the years I have owned a lot of turntables, cartridges and phono preamps, and based on my experience here's what I'd suggest -

First, you already have a very good turntable and arm. I wouldn't mess with replacing either if they still function properly. Instead, I would suggest doing the following - look for a good pre-owned phono preamp on audiogon - a good choice would be an EAR 834P. The 834P can handle most MM and MC cartridgesThen, I'd purchase a Nitty Gritty 1.5 record cleaner, which will do more to improve the sound of your records than any other tweak you can buy. Then I'd take the balance of the $3000, whatever is left, and buy a new cartridge fro Shelter, Clearaudio, or Grado -- you might call the good folks at Needledoctor, if you don't have a local dealer you like, and ask for suggestions.

Or simply spend $500 on a mint used $1500 cartridge. I've done it here more than once. The last one I acquired, a Benz wood SH scoped out as a new cartridge would...the stylus showed zero wear. Your table is fine, now it's time to deck it out with a better stylus...there are a ton of nice used cartridges always for sale on AG. Buy one from a reputable seller. Better to make one change at a time so you can hear the differences you're making in the system. You can always upgrade or change electronics at a later time...baby steps...life's rule, not mine :)

I'm guessing your PS Audio phono stage is the GCPH phono stage which is no slouch. That phono stage sounds pretty darn good and if you try to replace it (without spending a fortune) I think you might be disappointed. I agree with others that said replace the cartridge. And I absolutely agree with Coltrane1 one change at a time.

If your preamp is the Ayre K1, it probably has a phono preamp in it...line 2, but maybe not indicated. If it doesn't, you can get Ayre to put one in...I don't know the cost, but it is a fabulous phono stage.
