Angel City Audio is owned and operated by Hugh Nguyen, a longtime audiophile and founder of HTN Enterprises. We are a different kind of audio company, eschewing direct sales as well as large scale brick & mortar presence in favor of a small network of dealers across the country who function as a team. This allows ACA to focus on product without managing a large company and all the associated distractions, while still maintaining a close link to the dealers and a short path to the customer. Our dealers are an extension of us and partners in this endeavor - not just retailers.
We hope to bridge the gap between the traditional audio purchase experience and the internet direct sales model by offering personalized service and an equally strong focus on both the online community and traditional high end buyers. Most importantly, our focus is you!
