## About Budget Audiophile
Budget Audiophile (budgetaudiophile.com) is an independent, US-based hi-fi resource focused on the
"budget audiophile" niche: TPA3255 Class-D amplifiers, discrete R2R ladder DACs, hi-res streamers,

Onkyo Muse/Icon Series, Sony CS Series, Soundcore, Koss, 3e Audio and other value-first brands.
We publish honest, hands-on reviews and curate real price-to-performance picks with community-voted
YouTube reviews (cheapaudioman, Erin's Audio Corner, Passion for Sound, Old Guy Hifi) and link out
to direct-from-manufacturer and Amazon US options side-by-side. Being a budget audiophile is about
spending smart, not spending the least - maximum sound quality for every dollar.
