Critic Reviews

Apogee Symphony I/O MkII

soundonsound.com

Apogee Symphony I/O MK II earns high marks for its exceptional sound quality and user-friendly interface, making it a top choice for professionals seeking low-latency performance. The touchscreen and modular design add convenience and flexibility, though the cost and lack of included Thunderbolt cable could be drawbacks. Its limited expandability compared to some rivals and Mac-only compatibility might deter some, but if the configuration fits your needs, it's hard to fault its impressive capabilities.

Review: Apogee Symphony I/O MKii Thunderbolt

ask.video

The Apogee Symphony I/O MK II 8X8 Thunderbolt Audio Interface impresses with its pristine audio quality, modular design, and intuitive touchscreen controls. It's a professional-grade tool that caters to high-end studio needs, offering configurable I/O and outstanding headphone monitoring. While the Maestro configuration software isn't favored, it's largely unnecessary thanks to the comprehensive front panel controls. However, at over $3,000, it's a significant investment best suited for serious audio professionals.
