Dear @edgewear : The issue is not about FR but what showed your Anna in those both FR tonearms that just said the FX truly was and is spot-on with.
The Anna is not only a " so so " tracker along those 16grs. on its weigth.
I owned the MAX 282 with all its 3 arm pipes and two but the J shapped 237 and I mounted there bad bad trackers to exceptionall trakers/ heavy ones and not so heavy and never had any single trouble with mistracking in any MM/MI/MC over 100 cartridges in cluding Ortofon but not the Anna. The gyroscopib MS tonearm bearing is really a beauty..
About the SUT issue it's not that I'm " against " it per sé and for several years I used SUT's , many to name it here including the best best SUT ever made exclusively to Denon by Murata : Denon AU-1000 that still I own and it's modified by me ( obviously not the transformers. ). Now a " few " years ago and even been owner of the AU-1000 a close friend of mine started and finished a " new " Phonolinepreamp that in those times outperformed in my system FM Acoustics.
We took around 2 years and a half to been finished and I still use in its version 3180, @lewm own the 3160 version and other gentlemans the 3150.
Why took we the responsability to build that kind of unit? easy: because no SUT/phono combination and top full SS active high gain units as the mentioned FMA truly even my way demanding analog targets till appeared the 3150.
All versions came with two totally independent ( including power supply ) dual mono phono active high/low gain stages even time to time I use its MM stage along the AU-1000 and is enjoyable.
Btw, we are thinking to re-start that phonolinepreamp design maybe with 4-5 latest version including one for me. This is in the desk because is not my business way of life and each unit time to build take a lot of time . We will see.
