Opus 1

Opus 1

Air Tight Opus-1 Ermitage cartridge, released in honor of Air Tight’s thirtieth anniversary. And, folks, it is just as much of a winner as its two distinguished predecessors - and certainly the best Air Tight yet.

"the Opus-1 reproduces changes in intensity, large and small, as a continuum, making the presentation that much more realistic and easy to listen to."

~ Jonathan Valin - TAS
