"Created, Designed, and Checked in the USA"
As far as I can tell, Omaha Audio has no connection with the city in Nebraska: its headquarters are in California, and the products are made in China—but "created, designed and checked in the USA." The system they were playing used their own speaker (named, fittingly enough, the Omaha Speaker), a fairly large two-way with some resemblance to Sonus Faber products ($2000/pair), the Omaha Tube CD player ($1600), and the OD-300B single-ended-triode integrated amplifier ($1400, photographed here by Larry Greenhill). At the Stereophile Ask the Editors session, Sam Tellig was raving about this amplifier and the value it represented. Based on the sound of the system (smooth, highly musical) I have to agree with him.
