Hi Perrew, it certainly would depend on the cartridge I want to use/listen to.
If the cartridge of choice would be any of the Lyras, Dynavectors, Koetus, Phase Tech or similar (means : medium to high compliance - most top-flight cartridges today do belong in this group) I would most certainly go for the MAX-282 or EA-10 as these would be the most versatile 12" tonearms and both are dynamically balanced and both can handle any cartridge weight.
I would go for the 12" versions whenever possible because of simple advantage in geometry (yes,... I know.... others have other favourites and do not see the big advantage in 12" vs 10" or 9").
But I see - and hear - it.
I would always go for a dynamically balanced tonearm ( the physic advantage is again obvious and beyond serious discussion (in real world applications as well as in the theoretical - again: if others have different opinions ... fine with me, I neither want to "know" nor "learn" their point of view. That is way past me.).
So - yes, it comes down to these two very similar designs.
Not because they are vintage, but because they are the most versatile and do offer the 2 key design features I know will give superior results and sound.
Cheers,
