I'll chime in with my own highly unscientific findings. Let me preface by saying that I'm well aware that my high end hearing has suffered over the last 10 years, and though not diagnosed, I have some form of tinnitus. This doesn't put me in a good spot for analyzing these types of subtleties, and so typically rely on recording tools to help identify these sorts of sonic problems....which can be pretty time consuming and the end result has to be worth it for me to embark.
So first, I just plugged in my headphones (not the greatest JBL cans) directly and gave it a whirl. With my basses being roundwound strung, and action a little on the clanky side, it was difficult for me to easily discern any overtly digital artifacts, though there were times where I was convinced I heard it, only to NOT be able to hear it with any consistency. With all the compression, loose harmonics or extraneous fret noise would be the most prevalent negative artifact I could easily identify. I'd hit a high note on my G string, fairly lightly, and let it ring. Other than the residual noise present from my bass pickups, I really couldn't say I heard anything alarming, or consistent/obvious as described by "ped" on the other forum.
Now, keep in mind what I said in the first paragraph. Also, for me the B3n and G5n (and B3 when I had it) were not really being considered as serious recording tools if push comes to shove. But I also feel pretty certain that I've laid down bass tracks on serious projects that were no better or worse sounding *to my ears*, currently flawed as they may be, and the only place where such noise would even be an issue would be during an extremely dynamic bass solo - with nothing else in the mix - and with very gentle playing.
I'll see what else I can conjure up, but for the moment I'm not concerned - only speaking for myself. If anyone else hears digital artifact noise and it's really bothersome, then so be it, and I envy your taste for such delicate sounds and the condition of your ears.
