Critic Reviews

Apogee Symphony I/O MkII 2x6SE

soundonsound.com

The Apogee Symphony I/O MKII 2x6SE shines for mastering engineers with its stellar audio specs and versatile I/O options, including low-latency Thunderbolt connectivity and a sleek touchscreen interface. It offers impressive dynamic range and THD+N measurements, making it a top contender at its price point. While its performance is commendable, especially when compared to pricier converters, some users may notice slight tonal differences in bass and mid-range detail. The updated Symphony Control software is a significant improvement, but the lack of a Thunderbolt cable at this price is disappointing. Overall, it’s a compelling choice for those seeking a high-quality and flexible mastering hub.
