Apogee Symphony I/O MkII 2x6SE

soundonsound.com

The Apogee Symphony I/O MkII 2x6SE is a powerhouse for mastering engineers, offering stellar audio specs and subjective sound quality that rivals much pricier units. Its modularity and range of I/O options make it versatile, with a standout feature being the improved Symphony Control software. While its bass response might feel slightly weightier compared to ultra-high-end converters, it still delivers impressive mid-range detail and clarity. The lack of a Thunderbolt cable is a letdown for a premium-priced product, but overall, the 2x6SE stands as a formidable, flexible, and affordable choice for mastering setups.
