"Listening to my RS1's through the Grado RA1 headphone amp is like listening to a live performance, it puts you right there." — Mark Rivera, Saxophonist with the Billy Joel Band

"With the Grado Reference RA1 handling the amplification, music was rendered truer, clearer, and more life-like than I had ever imagined was possible." — Willie Gluckstern, Audio Magazine

"When paired with the high-quality RS1 headphones, the RA1 delivers music that is clearer and more life-like than most speakers." — Jason Alexander, Satellite Direct

"The RA1 offers excellent value for money, and does a fine job powering phones from Sennheiser, Shure and Ultimate Ears. It does especially well with Grado 'phones and does not embarrass itself next to state of the art components." — Phil Gold, Inner Ear Magazine

"With a tube-like rendering of timbre and a sweet, relaxed sound, the Grado RA-1 makes extended headphone listening a joy. Although battery-driven, the RA-1 is more at home in your equipment rack or on your desk than out on the road. A beautiful wooden case finishes off this gem." — Reviewed By Robert Harley, Absolute Sound
