Grado RA-1 HG: High Gain Headphone Amp – No Longer Available

High gain headphone amp

Product Description

After years of relying on other equipment to drive Grado headphones, you can now listen and enjoy headphones through the new Grado RA-1 Headphone Amp HG.  Designed for state-of-the-art performance and specifically to play Grados, the new RA1 will allow you to hear your headphones like never before.  This new 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.

Also available the RA1-HG (High Gain).  Now headphone enthusiasts can utilize the RA1's sonic qualities with a wide selection of headphones.  The RA1-HG is designed to drive headphones with impedances of 100 ohms or more.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
