This little mahogany wood unit does a great job substituting for my home set up. It does not alter the sonics nor does it skimp on providing the power of my home setup. In short, it keeps me happy and looks good doing it. Highly recommended.

I have a history with high end audio as my old home system was a $25,000 setup for stereo only. An amp, CD player and speakers. I sold that 2 years ago and now have been trying to find a perfect headphone setup. So far I have tried HD800's, HD598's, T1's, and MANY lower end Apple store and Best buy cans (which all were awful).
I found the PS-500's which I love and they have THE sound I was looking for. I was running them with a dacmagic dec and a Fiio amp. They sounded good. I added the RA-1 and the sound jumped from a bit etchy and trebly to smooth, liquid, full and gorgeous. This little box may have been made with cheap innards but there is a reason it has been selling for a LONG time as is. It works amazingly well with GRADO cans. Period. Can you get better for $350? Im sure you could but right now I do not care as the sound I am getting is magical and EXACTLY what I like, and the RA1 is a beautiful and SIMPLE amp. I like it but wish I bought the AC version as I see myself going through batteries quickly.
$350 is not bad for what you get sound wise, if you are using Grado headphones. I've had high end head amps as well, but this is basic and simple and it works.

Straight a/b between iPhone output & iPhone through this amp. Worth every penny - to the kind of person who owns Grado 325's. Read morePublished on May 25, 2012 by Honest Opinion - hacker.
Yeah it works. It looks like it was made by a third grader though in the 1950's lol. Some people have way too much money for useless stuff. Read morePublished on December 30, 2010 by K. Daejin
Ok, this is a little better than the sound card in my macbook pro. My apogee one audio interface is almost as good. Read morePublished on October 31, 2010 by Yasin Cakal
