Grado RA1 headphone amplifier review


Grado RA1 headphone amplifiers

Audiophile-grade headphone amplifier; elegant solid mahogany case.

You'll hear a loud pop through the headphones when you turn the RA1 on or off; only the RA1-HG model plays loud with non-Grado 'phones.

This remarkable little amplifier brings out the best sound from your headphones.

I've been reading these reviews and based on these reviews I bought a used RA-! for just a little over half the retail price. Prior to this I have been using a Creek OB-11 with Grado 325's.
