The Klipsch Custom-1 and the FiiO E5 Portable Amplifier is a perfect match.. small dynamic compact. The Bass boost on the E5 help to counter Custom-1 weakness which is BASS!!
The so called HISSING sound with this COMBO is also very minimal..
Now still doing the burning test.. Will do a mini review later.. :P
The FiiO E5 is barely larger than my Ipod Shuffle..amazing feature in such a small size..
Custom-1 come with a cool carrying case..very premium quality..
