Interesting thought- Linn &

Zavato,
I was once a Linn fan and had an LP12 for years.  I never was able to get my LP12 to make me happy no matter what the upgrade. But thats me. I do remember swaping out my power supply and motor, but I don't remember to which one.  It was expensive and I had my Linn dealer do the work.. My point is, that it made not one bit of difference in the sound. My dealer kept trying to convince me that I would hear a "world" of differences and experience spooky black backgrounds and incredible dymanics, etc, etc.. My wife and I couldn't hear any change whatsoever.  

If your'e looking for improvements in your Linn, maybe consider a new tonearm or cartridge?  Or do what I did.. Try and old idler wheel drive table.  I rebuilt and old Dual 1229, replaced the tonearm with a Grace 747 and never looked back. It's the quitest, most dynamic table I've ever had in my system. I also have a grease bearing Garrard 301 with a SME 3009 that is equally as dynamic.

Maybe your Linn dealer has a table fitted with the upgrade and you do a "A/B" comparrison?

Best,

Norman

Zavato,
Unlike Norman above, I added a Radikal D to my Linn and the difference was easy and clearly heard. The Radikal D is a huge improvement to the Linn TT.

Do the 'AB' with the the VPI Prime...and compare it to a Linn LP12 Radikal D; I suspect ( strongly) that the idea of adding the Prime will quickly fade away, LOL.

I'm not dissatisfied at all with my LP 12- mine works and sounds great! But I do like variety. Why in the world would I own 3 distinctly different headphone amps? One is an OTL tube amp, the other also a tube amp but not OTL, and the there's a SS amp. It's for variety 

It just appeared to me to be fun to have an alternate table- I can imagine the Prime with a Dynavector cartridge! 

If you want fun then invest in a Direct or Idler drive like the Technics SP10 Mk2 or Jean Nantais Reference Lenco or a Loricraft Garrard 301.

An LP12 with Radikal is a much higher level of playback than the Prime IMO so you will not exactly gain in terms of fun.
