OK, I've decided and ordered a Phantom.
My bottom line reasoning was (a) it has the adjustment flexibility of the Triplanar, but the adjustments are easier to make, (b) its craftsmanship, fit and finish are up to SME standards, (c) I called Bob Graham and he told me that his personal TT is an SME 30/2 and he developed the Phantom on the 30/2 and on an available 20/2, causing me to reason that the Phantom should be at least as synergistic with the 20/2 as the SME V and probably even more so since it was developed more recently on SME's current TTs and with the current best cartridges, (d) the guy I bought the 20/2 from is replacing it with the Grand Prix Audio Monaco TT, an unsuspended design I believe, and he evaluated it with the following arms: Dynavector, Phantom, Triplanar & SME V, which finished in that order top to bottom, with the Universe, XV1S, top of the line Lyra, causing me to reason that the Phantom should work very well with the Galibier tables, a theory I hope is born out when Thom does find the time to evaluate the Phantom with his tables (so it should work equally well for me with Galibier), (e) Bob Graham put a lot of time and resources into developing a current state of the art arm so it should have bettered most if not all of the current top arms out there, (f) being among the latest designs-redesigns among the top arms makers, it should be around a while.
In other words, I've listened to the many excellent points made by each of you on this thread, and I think the Phantom satisfies more of those points than either the Triplanar or the SME V, at least for my purposes.
BTW, Bob Graham is a really nice guy, very approachable and easy to talk with and he's using a new bearing (Swiss-made, I think) with the Phantoms he's making now which he says surprised him at how much better it was than his initial bearing.
Next up, which cartridge with the 20/2 and Phantom?
Thanks and best to you all. I will keep you posted.
