Not to try to create a bad vibe,but the Triplanar does have some important warts,that the mfgr has NOT,to my knowledge corrected.Since so many of us are so critical about the most minute detail of analog,I have to mention two of them,and would be a bit surprised if(unless they have been corrected)owner/defenders got uptight.
Firstly,the VTA "dial" on top,has too much play.It is useless in terms of "sighting" in a numerical setting,and being able to "for sure",go back to it by sight.Sure it can,and should be set by "ear",but after having an arm that is supremely accurate here,after owning the Triplanar,the accuracy and repeatability can easily be appreciated,and is more than easily dismissed!
Secondly,since it has become almost painfully obvious,how incredibly small amounts of downforce(1/100's of a gm)can affect sound quality,in a really good rig,the Triplanar's "hunt and seek" twisting/pushing of the counterweight is,let's say "not fun".Especially if you want to zero in on specific downforce weights.Once again,when you have had an arm that does this much more accurately,and easily,it becomes "more" of a big deal.There are arms of similar performance,and maybe a bit better,that offer these features.
None of this is of earth shattering importance if one doesn't mind fotzing around,in some cases for an afternoon!Obviously,the Triplanar is a wonderful arm,or it would not be so popular.I DID like mine.ALOT!!
Also,my Graham 2.2 is FAR from perfect,though it dispenses with the problems I just mentioned (the criticality of that darn fluid is not a "fun thing",if you want to go all the way,with performance)and the cartridge choices can be somewhat limited,which I'm not wild about.Yet,it is a HECK of alot better than many 'scribing here can/will know.I have no axe to grind,regarding any of the great arms,we all love to talk about,and am not going to "go off" about anything,like the past,but fair is fair!
Truthfully,I believe any of our favorite arms,discussed in these threads,will have their own specific idiosyncracy(hope I spelled that OK),but we DO lean,a bit too much to the "chosen few".That's perfectly OK with me,btw.I love to ponder them all!!
Best!
