VPI Classic 1 to Prime Signature upgrade question

[jdsher]

The oldest piece of equipment in my system right now is my turntable, a VPI Classic 1 I purchased in January of 2013. I had a Lyra Delos originally mounted that I upgraded to a Kleos about 2 years ago. I love this turntable and find it difficult to imagine that a turntable upgrade could sound any better, but I was considering a move up to the Prime Signature. I like the upgrades of the "Prime Signature" vs the std "Prime" and feel it's worth the extra dough, but I would love to hear any suggestions from those in the group that have listened to both.
Thanks,
Jon

I haven't heard a Prime Signature, but personally I would consider just upgrading to a 3D tonearm. You'd also need a new pivot spike which is about $100 from VPI to use the 3D arm. And you can also upgrade to the HW-40 feet if you'd like.

Thanks Maks for the response. I hadn't considered upgrading the arm, but I have already upgraded the feet to IsoAcoustics Gaia II and that did make a difference.

Ah so the upgrade bug has bitten...
