How I listen music ?
I own an Iphone 3GS and I use Shure SE 530. It was my first valuable headphone and I really appreciate them. I'm looking for a new headphone, probably a Grado, but that is not the issue in this thread.
When I'm moving, I use Iphone with the Ipod fonction and I did install the spotify app on my Iphone. For that, I encoded all my CD collection (AAC 256 and/or Apple loseless format).
When I'm working, I use my laptop and the Spotify client.
What I use to listen ?
I listen to a wide range of music. Bach, Daft Punk, Motown's stuff, funk and Jazz. I like to have a neutral sound, well balanced.
Why I needed an amp ?
After few weels of use, I found that my Iphone miss a little bit punch and power. It was like the sound was "blank". After reading a lot of reviews of head-fi, I've tought I may need an amp. But i would not spend at this time to much money on that. I found that topic and decided to give a try to it.
I've contacted John who kindly answered me before I bought his amp. He answered very qickly to all of my questions. I really appreciate that. After buying, he sent the amp qickly and I get it in a couple of days : that's fast for an onverseas transaction (I'm living in France).
Does it worth the price ?
Definetely yes. What I was looking for - a reacher / warmer sound - is there. The price was not overestimated nor the shipping costs (thanks for not asking 20 US $ like others John).
His amp is well done, I appreciate the retro design. It's simple, really easy to use. And it works perfectly.
I would recommend this amp to anybody looking for a better sound. I will update my comments after few weeks and maybe after buying a new HP.
