124 bro, (same as Antelope's Goliath but theirs can boost to 132) UA Apollo is only 120!
I stand corrected, Shawn. Trust a bloody Virgo to correct a Virgo, I say.
Still, very-good convertors. Mastering-grade, apparently, but only 1dB quieter than the MOTUs.
Of course, this is esoteric stuff. Anything beyond 100dB should be more-than-adequate given that until recently, with a few notable exceptions such as the EMU EIV series of the '90s (110dB from the expansion outs), the synths, drum machines, FX and guitar processors out there topped out at around 100dB, most in the high 80s and 90s. Vinyl records yield mid-60s, typical cassette decks in the 70s or '80s if excellent, and the ol' CDs' theoretical limit was 96dB, and no player actually achieved that due to physical-component limitations.
So, 100dB is nothing to be sneezed at, and anything approaching 120 or even more is insane for an interface. We're so-spoiled these days.
SSD5's dynamic range will be huge, BTW, with the new playback engine. Resolution will be spectacular IMHO. We'll see I guess...
