Digital camera reviews of FiiO E7 USB DAC and Portable Headphone Amplifier (Black)
Digital camera Review: ...Aside from connectivity problem, it does work but not miraculously (REVISED & UPDATED)
Summary: 4 Stars
REVISED & UPDATED
[Just out of the box...] The touch & feel and finish of the product is solid and I love the fact that fiio thinks of everything providing you with a screen protector and silicon glove jacket etc. Good instruction sheet.
During the first 20hrs of burn, I could not discern any improvement in sound quality on my K702 amped by fiiO E7 and driven from iPod Classic - if anything, I thought there was a slight drop in sound clarity and separation. I was already very happy with the K702 unamped as the signature suited 95% of my music repertoire which comprised largely accoustic, tenors, mid vocals, etc.
What the E7 did however was to raise maximum volume by 10% which was irrelevant for me as I had found maximum volume driven from the iPod quite sufficient for my K702. [Max iPod Volume = 53/60 E7 Volume) Ditto the iPhone 3GS. Setting the EQ Bass boost to +1, also improved bass presence in rock music eg U2, BonJovi & Black Eyed Peas. It afforded elegant ambient bass, adapting the sound signature of the K702 for listening to genres with more bass (but not heavy metal) Happier now ...
However, whilst there is a plus(+) I also found a minus (-)...after jiggling the LOD jack (1/8") several times in and out of the E7 Line In Receptor (bottom right), I suddenly found that connection was compromised and needed to be tweaked each time for optimum sound or it toggles between stereo and a hollow distant mono sound with parts missing. Does anyone else have the same issue. I am a very careful person btw. A little disappointed in that considering its $99 and not $59.
Apart from that my compliments to the design team - you've done well. Looks great. Feels great. Bass is enriched without needing a pair of Denon AHD2000/5000/7000. But production team please tighten your Line out jack receptor.
[K702 at 30hrs plus of burn] Following advice & having left my hp on iPod via E7 (stationery) most of yesterday & today, I am starting to hear a slight improvement in the amped version which wasn't there before. I hope I'm not one of those who are imagining a diff to console myself. No I think I get it...what was previously a drop in clarity has now become "SMOOTHER" richer sound via the E7. However, I still haven't resolved the connectivity issue but am suspecting it could be a combo of a faulty L3 wire and loose Line in port. TBC.
