What genre do you usually listen to?
I have only tried it with two cables before, namely the Whiplash TWag V2 and my own Stage93 93spec.
The TWag V2 makes it sound more quick and edgy, cuts down a little of the lushness and also a shorter but sleeker note delay with a lil more 'bite' which many will find it just nice for the right genres.
I would personally prefer the TWag V2 for EDMs;Dubsteps etc, genres that requires a quicker, sleeker response with wider, left-to-right horizontalally expansive soundstage to boot.
On the otherhand, 93stage makes it sounds a little more lush-sounding yet less thicker note at the same time with more transparency, Vocals shine a lot more and takes the center stage with improved transients which is the smoothest, liquid sounding of the 3 (among Stock, TWag V2 and 93spec)
I would prefer the 93spec for Vocal Oriented Genres, from Pop to Vocal-Oriented Acoustics, Jazz and Bossa Nova.
Either way I don't think you will go wrong, although I went for 93spec because they were relatively cheaper than the TWags and benefits my preferred genres more.
Fyi I am using them on DX90 (High Gain). And ymmv, best thing is to try it if possible before buying.
(P.S. If there is any other fellow FX850 users here from Singapore (apart from
Leo888 it will be good to meet up and let more people try the cables for more opinions on different rigs!) =)
