The Linn is a decent turntable, but that is about as far as it goes. If one listens using a blind A/B, you'll never choose the Linn over a good idler or direct drive table. There are so many 'reviewers' who used to use Linn as a reference. Art Dudley for example. I was so excited when I bought my Linn, then when it was home and set up it was disappointing. My dealer told me to 'let it brake in', months went by, then a year. Then a cartridge upgrade, tonearm upgrade, bearing upgrade, motor upgrade, power supply upgrade, cables upgrade, plinth upgrade, it was never ending. Within three years time we had literally rebuilt the Linn. I had a Dual 1219 prior to the Linn, with cheap crummy cables, and it sounded better in soundstage, bass, definition, etc. It was just a more 'solid' presentation. To me… and that's what mattered. I bought the 1229, rebuilt it, replaced the tonearm and am very happy. I then rebuilt a Garrard 301 and mounted a SME 3009 and it too is wonderful.
I have less than half the cost in the Dual, tonearm, Garrard and tonearm then I had in the Linn and that was with a custom plinth for the Garrrard. I am now going to be tackling a EMT, but that is going to take quite a bit as it's kinda rough and parts are expensive. I will do some of the work, then have a local shop finish it for me. It has to be perfect.
Enjoy your Dual, when you can, and only if you feel the need too, upgrade. But make sure the upgrade is an actual upgrade in sound, not just in cost.
Playpen, sounds like you've found some good tweaks to make the PE even better! =)
