Upon walking into the Napa Acoustic room, I heard many expressions of awe and disbelief as attendees searched for subwoofers and asked, again and again, if the products’ stated prices were correct. Indeed, the system here—Napa NA208 A amplifier ($399), NA208S speakers ($199), and DT-307C CD player ($399)—filled the room with solid, believable sound and music.

The brand made its debut at last year’s Jacksonville Axpona. While all of Napa’s current manufacturing takes place in China, the company’s Joseph Kwong told me he hopes to produce an affordable vacuum tube amp right at home, in Fremont, CA, in the not too distant future.
