What people say about the Grado RA-1 headphone amp
"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."
