    Soon to be year three for our OB Sigma’s. I look at other speakers and then remember I’d have to part with Sigmas and I rule the deal out. Bad recordings show glaringly but good ones make you realize there is no substitute for the Sigmas. Imaging, bass, mid range, are perfectly balanced. They are driven by Red Dragon monoblocks and an Onkyo P3000R preamp. My wife grew up in Japan and at first she thought the Sigmas were too small. She says they are perfect.

    I am a new owner of the OB Sigma. I have prior experience with open baffle speakers (through companies that specialize in them), and my early impression is that the Sigma OB offers exceptional performance at over half the price of those other brands. They seem to strike the perfect balance between the openness and clarity of an open baffle design and the dynamic punch of conventional box speakers. It pairs very well with my Doge 10 tube amplifier. It also has an unobtrusive, simple, and elegant design and the build quality is excellent. A hidden gem in the Tekton line up and a true bargain at this price point.

    Dear Eric,

    I set up my new Sigma OBs last Friday. I just wanted to tell you how amazingly pleased I am with them already, although I haven’t even put 15 hours on them yet. I’m usually hard to please having auditioned or owned various B&W, Magico, KEF, Martin Logan, et al speakers. Your OBs have tremendous musicality, a wonderful wide and deep soundstage, terrific delineation of individual instruments, driving bass, and a delicate high end. The overall coherence is impressive.

    I just finished listening to one of my favorite cuts- Morning Dew from the Grateful Dead’s live at Cornell show. The experience was overwhelming. Who needs sex?

    Again, thanks for your exceptional and budget worthy speakers.

    Richard
