These headphones will make you smile and shake your head in disbelief. To get this kind of sound with a home stereo you would have to spend tens of thousands.    

When I first turned this amp on and plugged in my Grado RS1i's, I just said "wow, this baby is smooth and sweet". I feel the same way when I use them with my Audeze LCD2's. I use the amp almost everyday and I am very happy with it. The battery life is very good. I highly recommend this amp. It's a keeper!!

I had a 39.00 cmoy amp and  decided to order the JDS Labs because of all the positive reviews. I found the JDS has less gain than the 39.00 cmoy (The JDS cost 69.00). The JDS is build with much better components and sounds a little better so it is worth the extra 30.00.
