Grado Labs Reference RA-1 Headphone Amplifier - AC Version

Your quality headphones get a big performance boost with Grado's RA-1 reference headphone amp. And the AC version brings new convenience to the Grado. You get the same great sound as the DC model without having to worry about battery consumption. Just plug the Grado into a wall outlet with the AC adapter and premium power connection that won't pop out of the back of the RA-1 like bargain AC adapter jacks often do.

"With the Grado RA-1 handling the amplification, music was rendered truer, clearer, and more lifelike than I had imagined was possible," proclaims Willie Gluckstern in Audio magazine.

High-Current Output Capability

Machined from a solid block of mahogany, the RA-1 uses a pair of audiophile op-amps with high-current output capability and wide bandwidth. Hook it up to any line source, portable or in-the-home, and luxuriate in the warm, smooth, full-bodied, rich, non-fatiguing sound.

Designed for state-of-the-art performance and specifically to play Grados, the new RA-1 will allow you to hear any brand of quality headphones like never before. Sound quality is warm, smooth, full-bodied, non-fatiguing and rich. Drive your headphones to their full potential. Get an RA-1!
