I was considering exchanging my Wadia 860x with a Wadia 16, and contacted Steve Huntly for his opinion, and here is what he had to say comparing the two:
I think that an "i" version of the 16 can be brought well beyond the
performance of an 860 but in all honesty it would be trade-offs to some
degree between a regular 16 modified to Reference level vs a stock 860x.
Personally I think the modified unit would be more musical, more dynamic,
more involving, but I would still have to say that the 860 would be a bit
more open, more transparent, a bit more detail, etc. Which choice is right
depends on your musical priorities and your system I guess.
