Product Description

Amazon.com Product Description

The best way to enjoy the stunning quality of Grado headphones is with the Grado RA-1 Battery Powered Headphone Amp. Built from a solid block of mahogany, the RA-1 uses a pair of audiophile op-amps with high-current output capability and wide bandwidth to deliver true, clear and lifelike sound into your headphones. Two nine-volt batteries will drive the amp for a full 40 to 50 hours. Just hook it up to any line source -- portable or in the home -- and luxuriate in the warm, smooth, and full-bodied sound that has built Grado's world-wide reputation for high-quality headphones.

Product Description

After years of relying on other equipment to drive Grado headphones, you can now listen and enjoy headphones through Grado Labs' Reference Headphone Amp, the RA1. Designed for state-of-the-art performance and specifically to play Grados, the RA1 will allow you to hear your headphones like never before. This amp is machined from a solid block of mahogany and measures 5" wide, 5 1/2" deep and 1 1/2" tall and weighs in at 12 oz. The RA1 is available in an AC version or can be powered by two 9-Volt batteries that will drive the amp for 40 to 50 hours of listening pleasure. And the sound? Just like all Grados: warm, smooth, full-bodied, non-fatiguing and rich. Hook it up to any line source (portable or in-home) and drive your Grado headphones to their full potential.

5.0 out of 5 stars ra1, June 5, 2009
I wired this to my imac to listen to my Grado headphones. There is a fullness, not volume, but full sound. I also have a pricey set of B&Ws to compare. I dont regret the purchase. Not to mention the mahogany amp looks good on my desk.
