Avid Diva II SP or keep my Linn

The Ittok is a damn good arm, IMO.  If it's bottom you're looking for, I would consider experimenting with the shelves.  I have never seen a turntable more affected by what it sits on.  Mine was mounted on a wall shelf and we started with a plywood shelf I think.  We then changed to a Neuance shelf and the setup guy looked at me, as if to say - "Are you kidding?"  The whole bottom end opened up tremendously.  So fool around with that if you're so inclined. 

I have heard the Avid models. Avid Volvere and above are very good TTs. The Diva is nothing to write about.  The Diva actually sounded bright and somewhat digital like.
Instead a Rega RP6 and above are much much better. You get a serious TT from Rega with very good analog presentation.

My rack is fairly dense. would a lighter table help??

Did you hear the Diva or the Diva II SP which is twice the price?? Thanks for your input.

That is exactly what Linn says not to do.  Try building a mini-shelf on top of the rack.  Use a piece of Corian or whatever and put 3 or 4 cones under the shelf.  I guarantee you'll hear a big difference.  Better or worse?  That's up to you.  The Neuance was sort of a hollow piece of foam, sort of like a surfboard.  It was about 2" thick and very light and rigid.  But I also found that Corian worked well.  Even glass on the Naim Fraim, which is usually a no-no.
