i think the ssl MX is my favorite at the moment... but never heard some files from this converter. and the MADI only is a bit scaring because i cannot easily expand with e.g. a spdif high end monitor DA... if the SSL would have adat i would suddenly buy and connect with RME raydat.
im coming from RME (multiface, adi-8, adi-2) converters... the console was in cellar for some years and i was ITB all time. so the adi-8 was sold back then... now adi-2 is my monitor DA and critical recording AD, multiface my synth connection.
i love the RME hdsp system because its over ten years in nearly daily use and still rocking with all driver support ect.
i make ALL kind of music exept german folk music
from film music, commercials till prog rock and electronic... so i reord all kind of instruments and a lot of vocals. the console (A&H system 8 1616) is for sure NOT high end its really old school 80s but i missed it more and more especially for rock and electronic stuff, music that need "balls" or color. on th other hand i like the analogue way of integration all my growing hardware stuff.
(for filmmusic and all the boring stuff i will stay ITB furthermore)
converterwise i prefer the 3D effect some converters deliver some not! sometimes its quite obvious to hear. from compasion files ive heard on GS i like the apogee 16X converters most. but i dont know if this "old" stuff is still a good choice today. and i dont want to buy a used system...
