Selling my trusted Apogee Symphony I/O Mk1 in very good condition.

This unit has been the centrepiece of my professional recording studio and has been used on records that have collectively achieved millions of streams worldwide across Spotify, Apple Music, YouTube and other major platforms.

The only reason for sale is that I have upgraded my studio computer ecosystem, and newer Apple Silicon Macs are no longer officially supported by the legacy Symphony Mk1 software and driver architecture. Otherwise, I would happily continue using it.

Why This Unit?

The Symphony I/O Mk1 is widely regarded as one of the best-sounding interfaces/converter systems Apogee ever produced.

Features include:

  • Premium Apogee AD/DA conversion
  • Exceptional stereo imaging and depth
  • Extremely detailed transient response
  • Low-jitter clocking
  • Professional studio-grade build quality
  • Modular Symphony platform
  • Used in countless commercial studios worldwide

Many engineers still prefer the sound of the original Symphony converters over newer interfaces due to their musicality, clarity, and analogue-like presentation.

Condition

  • Fully functional
  • Very good cosmetic condition
  • Light signs of studio use only
  • Always kept in a smoke-free professional studio environment
  • Rack ears included
  • See photos for exact condition

Important Compatibility Note

Please do your research regarding computer and operating system compatibility before purchasing.

This unit is best suited for:

  • Intel Mac systems
  • Earlier macOS versions
  • Existing Symphony-based studio setups
  • Users looking for premium standalone conversion

It may require legacy drivers depending on your operating system and workflow.

Included

  • Apogee Symphony I/O Mk1 main unit
  • Power cable
  • Installed I/O modules as shown in photos

This is an opportunity to own a piece of high-end studio hardware that has helped create commercially released music at a professional level.

Feel free to message me with any questions regarding configuration, compatibility, or setup.
