Clearaudio have three tangential arms. I have not seen them. Another approach is put a DS Audio (optical transducer) in your arm, as I have done with my ET-2. Tangential is good for optical transducers because the skating can be well controlled.
I’ve heard the Kuzma 4Point11, SME V & Graham for many years with a variety of cartridges - friends still have them. I’ve had the ET2 for 30 years, along with a few other arms Naim Aro, Dynavector, FR64S.
None of these will "eat the ET2". You are more likely to go backwards.
Give the ET2 a birthday and send it back to Eminent Technology for a full service.
You can get it upgraded to ET2.5 but that will require revisiting air pump requirements.
In terms of soundstage transparency, tracking distortion, and coherency no pivoted arm can match it.
I am..sort of…with @dover on this…at this level, we are trading nits, definitely not LUNCH….i have a Triplaner but could be just as happy w ET2.x…. i agree, get it overhauled, upgrade pump, hush box, etc…
Enjoy the music
Wow. I loved my time w/et2. I sold it as package deal in the 90s. I just stopped doing analog during my child raising years. I would have zero issues returning to one given the years of killer sound it gave me. Some people's narrow definition of what works for everyone says more about them than the equipment being discussed. I trust my ears more than anyone's opinions or religion.
