An article has been released on the famous Headfonia as the first article for 2011's to issue kinds of
reviews for FiiO's desktop amplifier E9 and has exquisite pictures.
Address of reviews: http://www.headfonia.com/fiio-e9-dekstop-amplifier/
The summaries from chief editor:
For a total budget price of around $200 (depending on different retailer pricing), the Fiio E7/E9 combination is quite a good value entry level product to have.
Some competitors in the price range would include the Audinst HUD-MX1 and the Nuforce uDAC, but none of them have the headphone driving ability that I found
on the E9 to have. I think Fiio has progressed a very long way from the dayswhen they released their E3 amplifier.
Thanks Michael for the review and the exquisite pictures!
