When it comes to THD+N as an indicator of audio performance, low is good.
Most high-end converters exhibit a THD+N of –105 dB or better across the audio bandwidth. We spec the SYS-2722 at –112 dB. And that's conservative.
We could quote THD+N at the sweet spot of the curve and claim –118 dB. But that would be misleading. We prefer to adhere to best practices and publish a value that is true for the entire input range of the instrument.
Even within these constraints, the SYS-2722 is the industry’s undisputed performance leader, which is why AP is the standard for engineers who need their numbers to speak loudly.
