About Tube Audio Design
Tube Audio Design (TAD) was a boutique hi-fi audio brand founded and operated by Paul Grzybek (also known for Bizzy Bee Audio). TAD specialized in high-value, high-quality tube amplifiers and preamplifiers, including well-regarded models like the TAD-60 power amplifier and TAD-150 preamplifier. Products were designed by Grzybek, manufactured to his specifications by a reputable Chinese OEM, and hand-finished in his Wheaton, IL shop. The brand gathered a loyal following due to its musical sound, component quality, and Paul Grzybek's integrity and customer focus. TAD products were sold exclusively online and praised for their value in the audiophile market.
