Fiio E17K ALPEN 2 USB DAC Headphone Amplifier

Big Features, Bold Sound - With Comparisons to the Fiio Q1, E18 and Chord Mojo

ryanjsoo

Pros: Feature rich UI, OLED screen, Clean sound with a hint of warmth, Refined treble, Quite resolving

Cons: Price/performance isn`t as great as the Q1, Chamfer gets scratched, Could come with an OTG cable, Scroll wheel could be more sensitive

Introduction – The e17k is technically a higher model than the Q1 but it is also older. It actually uses the same DAC chip as the Q1 (PCM 5102) but the 17k has a cleaner, more complex amp section. The USB receiver is also improved, allowing for higher bit depth file support. It is interesting to see the sound changes based purely upon the amp and the e17k provides performance that is...

“ Sound: They expanded the soundstage a noticeable amount as well as instrument separation between the 2 channels. However, at first listen on the standard music app, i found the vocals to be a little muddy or low end heavy. Not enough treble to bring out the details of the instruments or the singer's voice. So I tried using it in conjunction with the EQu app and to my surprise i found it...” --Player1josh46

Headstage Arrow 12HE

“While I was scrolling through previous reviews of the Headstage Arrow something became apparent: some things never change. The Headstage Arrow comes with a tradition. If you want one, you’ll have to wait for it. Up to the point the wait seems unbearable - and then some. But as always when you finally get it, it’ll have been worth it. Besides the wait, Robert (Headstage is a one man company...” --flinkenick

“   Here's my long-delayed E12 review on an early pre-order model. I waited to get a good feel with many songs before posting this, and a good feel for how the amp affects the sound presentation. I tested it with my standard playlist to get a reference point of view, but you'll see references to other songs sprinkled throughout the review that I think are relevant for illustration purposes....” --Evshrug

JDS Labs C5 Headphone Amplifier

JDS Labs C5 Headphone Amplifier

“Introduction A bit of preamble - I bought this C5 amp to go with my FiiO X5ii and Fidue A73 set up. The idea was to get the amp to reduce the noise floor and offer a bass toggle for when I felt I needed it. I wasn’t expecting (or needing) much of an improvement in sound quality or sound signature.   I'd asked for advice on Head Fi forums, but had no responses. I’ve since be told...” --mellowjamie

(will check whether pot knob gets caught on the case) (edit: yep, that's it, no real quality issue there) To my surprise, the unit does not come with a 2RCA->3.5mm or 3.5mm to 3.5mm .I only had a fairly long...” --svyr
