Amp for Grado's

First of all, I would definately recommend the Grado RA-1 amp to compliment your sr125's.

Secondly, you need to visit www.head-fi.org if you haven't already. It's a headphone enthusiast forum with a fantastic group of people. I've been a member for the past few years and I haven't found a better forum anywhere on the web. You'll find all the info regarding headphones and amps that you need.

Good Luck

Without a doubt Grado RA-1. I own the RS-1 and Senn 600s and the RA-1 was designed to have synergy with Grado headphones and it does. It works good for the Senns also, but it really makes Grado headphones sing.

I use a Headroom Max with my Grado RS1s with great success, for what it's worth.
