I agree with much of what has already been said regarding the JCF's.
I've owned the DA8T, DA8V, AD8's since they first came out and have used them on countless albums and songs (mixing and tracking).
The AD8's are big, open and have weight. Tracks recorded through them have clear high end without any hype or digital grain, the mids are meaty and textured and the bottom just sounds right -I wouldn't call it tight or loose -bass and kick just work in the mix really well. I won't go back to a conventional AD when tracking, things just sound less interesting and smaller without the JCF's.
I use the DA8V tube and DA8T solid state DA's along with the two AD8's for hybrid mixing -drums, vocals, bass, guitars etc go out to the analog gear and back in the AD8's. Going through the DA>AD loop ads no noticeable digital grain or digital degradation, but things get even "bigger" due to all the tubes and transformers. I don't really think of them as converters but rather a 16 channel tube/transformer console that feeds my analog gear.
As far as the debate of whether converters should be neutral vs adding color all I can say is that any time I've tried swapping back to conventional converters (say Lynx Aurora, Apogee Symphony, Benchmark DAC, Dangerous DAC etc), I've much preferred the JCF's which is why I continue to use them after 20 years. They add something, but really, every converter does something to the sound, so given that fact I much prefer what the JCF's do.
Having said that, the only place in the chain I prefer a more conventional AD converter is when printing the stereo mix back to digital (after the analog bus comp etc). It's just the way I ride the horse; with the JCF's and outboard gear (and some plugins) I can get the mix where I like it and at that point, depending on the desired end result I either go to analog 2 track for a vintage tape vibe or lock in the mix as is with a Lavry Gold
...which...
sadly died a while back -apparently the circuit boards fry themselves after a while and Lavry won't repair them, uggh! So now it's a $7k gold door stop! I am experimenting with replacement AD's for the mix.
