“The S6 Black Edition was created to exceed the musical performance of the standard S6 version,” Nasta told me in an email. “Compared to the standard S6, we gained more power, better sonic detail, and the lowest possible noisefloor. “In general, when we design an amplifier, we look for instrumental and musical performance as sound scene reconstruction. We try to recreate a sound event as close to reality as possible, without artifice, that can be listened to for the long term. All with a touch of Italian design.”
So far, this all sounds sophisticated but analog-purist: old school. But that’s not the whole picture: The S6 Black has a built-in DAC. The “DAC3” module uses a Sabre ES9018K2M DAC chip. Inputs include USB (supporting PCM up to 384kHz and DSD to DSD256), TosLink, and S/PDIF.
