(Update) - The battery on the E11 is giving me about 4 hours of use before it needs recharging, this is less than half the life of a charge on the E5. I am going to replace the battery to see if it makes any difference.....Well I bought a new battery and this is just the same. This is much heavier on battery use than I expected.

(Further Update) The sound quality of the E11 is definitely better than the E5. I have had time to do some comparative testing over a number of CD's and on my iPod and there is a noticeable difference and on reflection, makes the E11 worth purchasing. The continuing disappointment is the battery life both with the original and replacement battery. One point to note is that when the E11 is put in-line with my earphones directly from the CD source then the quality is degraded from having my headphones plugged directly into the CD player. I suppose this is the trade off for getting the extra volume.

I have been using an E5 for a little while but as pleased as I was with it, I felt there was some substance missing from the sound. After reading the various reviews here on Amazon I decided to take the plunge and upgrade to the E11.

I am using it with Grado SR80i phones and an iPod Classic 160gb with all the files in Apple lossless format.

The first question I asked myself was 'Is the difference in price justified by the difference in sound quality?' and the answer is no, probably not. I would like to clarify this by saying that if I was starting out again I would jump straight in with the E11 but an upgrade from an E5 to an E11 is a luxury and not a necessity. I will however be keeping the E11 for use at home and the E5 for when I am out and about.

I'll start like many others have - I'm not an audiophile. However having invested in some decent bits of kit over the last couple of years I think I've started on the journey.

About 6 months ago I upgraded my Etymotic ER6i IEMs for Etymotic HF5 IEMs, as I was looking for something with improved clarity that wouldn't break the bank, and couldn't afford the ER-4P. I'm pretty happy with them, and I'm about halfway through transferring my CDs to lossless to get the full benefit. I use them with a 6th generation 160gb iPod Classic.

When I originally upgraded the earphones, I got a Fiio E5 just to test out what difference it would make to the sound. I'm sad to say it didn't as it was a faulty item, and wouldn't charge up so I returned it. The refund was swift, and that was that.

A few weeks back I saw that Fiio had released the E11, and although my previous experience initially led me to hold off, my intrigue got the better of me, and I took the plunge. I'm glad to say that I've not regretted it one bit. You'll struggle to find a decent portable amp at this price. I wasn't interested in a DAC or anything for home listening, as I have other equipment for this.

Firstly, it looks very nice indeed. Quite understated, but everyone at work has been pretty intrigued and asked what it does. Build quality is solid, and I've had no problems after about a month of owning it. The only downside I could find was that it cannot be used while it is being charged, however if you're using it out and about, a bit of forethought gets around the issue. I also bought a Fiio L3 line out cable to use, but may switch this for an iBasso cable.

A very neat feature is that it uses a mobile phone battery.

Was it worth twice the price of my trusty and well used E5.? Well made and smart looking product, and the sound.? Great, leagues ahead of the E5, and the bonus is of course the £44 asking price.Give it an esoteric brand name and 3 figures would be asked and still great value. Oh yes,it uses an easily replaceable Li-on mobile battery.Bass control,high and low gain switch to keep the knob twitchers happy.A solid rotary vol. control cleverly built to stop sudden accidental increase and decrease.This is a serious contender amongst portable amps.

Thought this was excellent for what it does until after a month of what I would consider light use (as in a few times a week) the input and output jacks started to crackle and completely lose sound - as it's been over 30 days since I bought it I can't return it which is why amazon's returns policy sucks and will not help you - my advice to people looking for a portable amp would be to either by headphones with a high decibel output and low impedance or just to suck it up and buy a professional grade one - I mean what's the point of forking out the best part of fifty quid on something that won't last 3 months when for a bit more you can buy something with a lifetime guarantee?

I am an audiophile who loves my music. So much so that I like to listen on the go. My home setup is reference quality and so I appreciate great sound. I used this amp connected to my ipod classic where files were encoded in Apple Lossless. I used Shure SE535 in ear headphones plugged into the Filo. (I still had their F7 model which I found to be unreliable with short battery life). The sound quality was greatly improved with a number of variable settings (Filters and Gain) available. Usine the Filo dock connector as opposed to the Headphone socket wrought the first major improvement. The amp itself then gives greater depth and tonality to all recordings. So much so that I found it hard to believe how cheap this piece of kit actually was. I have heard the Fostex HP-P1 which costs circa £450 and utilizes its own internal DAC. This is a great piece of kit which I plan to buy. However, the Filo did not fall far short of this superior sound quality. Again, when putting its price into perspective, it represents astonishing value for money. The volume control is indented and increases interstitially. The build quality is very good although Filo could have included a case or cover (as they do with their other and even cheaper units). I also have to ascertain where to locate those spare batteries. However, this is a good buy.
