Product Description

Well its finally here nearly 2.5 years in the making we are now totally certain it has been worth the wait. Featuring all of Graham Slee's knowledge and the know how to apply it we have a mini (portable) headphone amplifier (battery USB and plug top powered) that can take any line level source amplify and improve it to give real volume and kick to any headphones or earphones. With a form the size of an IPod Classic (6th generation) but being thicker the IPod can sit easily in the front recess of the Voyager mating together to create a formidable partnership. A number of other Pod players also fit. A separately available 3.5mm to 3.5mm cable allows the 'headphone out' of the player to go into the 'line in' giving excellent results and superb volume and bass. However when you buy a port to 3.5mm adapter bypassing the amp circuits of the Pod player and there inferior digital volume control this allows the Voyager to really impress. We compared it against newer and older model Solos and we liked greatly what we heard. The Voyager is light weight similar in feel to that of a classic pod player and comes fitted street-wear contour switch that is designed to improve the tonal range of street-wear headphones. For use with domestic and studio players that use Hi-Fi or studio headphones the flat position is generally more appropriate. The Voyager can be used in the office taking its input from line-out sources like the 3.5mm jack on many computers. While in use at the desktop it can be powered by a spare USB cord having a mini AB plug. The Voyager is supplied with an AC adapter that can power it when used at home or in the office. In use so fare we have chargers our G6 IPod 80Gb 4 times for 1 charge of the 200mAh NIMH PP3 9v cell and Its still going. Hi-Fi and studio quality stereo headphones can be used with the Voyager. When using high impedance headphones at home (typically 300 Ohm types and above) it is best used with high output line-level sources like a CD player ampli.

I have been around the block with headphone amplifiers working my way up through the ranks. I was aware of the Voyager some time back but the price always put me off since there were so many options from the likes of FIIO. Having owned a couple of FIIO amps (E5, E7) I was very impressed with the improvement they made to my iphone and headphones and never really believed that there would be much difference between those and the Voyager. Well, curiosity finally got the better of me when I had a few quid burning a hole in my back pocket and I decided to try one. Well, what can I say? When I first plugged it in I was lining myself up with my favourite tracks do carry out comparison tests between the Voyager and my FIIO E7, but I needn't have bothered. The difference in the sound quality was so big I never even bothered putting my FIIO back on, it was truly amazing how much more detail was there and I found myself flicking through all my favourite tracks. To the reviewers that have said that the Voyager is not all that, all I can say is that it must not be suitable with their equipment. I use an iphone and an expensive pair of Denon headphones retailing at £800, so I can only assume that these 2 devices were able to exploit the best values of the Voyager. As to the build quality, any audiofile will know that many cottage industry firms like Graham Slee will focus on sound quality before looks. My advive is don't spend £200 on a headphone amp unless you have already spent considerably more on your headphones and MP3 player. These devices cannot turn scrap into gold, but if you have a good quality MP3 and a good quality set of headphones and you don't have a hearing defect, then you will find this might just be the best £200 you have spent in a long time, particularly if you are currently using a FIIO E5 (£20) or E7 (£60) device, which are also great value, but not in anywhere near the same league as the Voyager

I bought the Voyager to pair up with my Grado RS1i's.

Very impressed so far by the sound quality and battery life. There are other products out there that are a tad bit smaller and hence more easier to carry around with an ipod but that is just a minor niggle.

The amp produces a very characteristic warm sound that have to paired up with a suitable headphone to take maximum advantage of. I have used all my headphones on these (Bose Triport, QC3, Grado RS1i and the Westone 3) and they all sound very good. However you if you prefer brighter sounds, then you will find that in an A/B test with the amp output vs the ipod output, the ipod output sounds better.

None of my headphones are really power hungry so I do not know how these perform with cans that have high impedance. Although I hear they are just as good.

In short a fantastic product, good build quality. Good options to power up, long battery life (mine's been running for over 45 hours!). Not five stars as it is slightly larger than the ibasso's etc.

Just a quick review after almost a year of ownership.
This amp takes around 200 hours of use before it is burned in and really delivers.
I use it with Apple lossless files on a Red Wine Audio iMod with a solid state disk, and an ALO iMod line out cable.
The amp drives both my Sennheiser HD650s and my Denon HDR 2000 headphones with ease. Deep powerful but clear bass, clear middle tones and a good top end without ever being harsh.
It will however show up issues with your source (it is an 'amplifier' after all) and so if you have digital music and not CD or vinyl, then you really should be using lossless files or those Encoded with the Apple plus (256k VBR) as a bare minimum.
Anything less, and you'll be sorry...
The amp delivers plenty of punch for around 60 -90 hours on a PP3 9v battery, but it's easy to forget to change it, and the amp will keep working - but the sound quality does eventually degrade as the battery drops off.
The looks are utilitarian, but it has survived a pretty hectic travel schedule, and a non too careful owner without damage. Not many other products I can say that about. The real magic is what is inside - so don't be deceived by looks.
In summary, this and my iMod are the heart of a great portable audiophile rig that goes nearly everywhere with me.
Oh, and the contour switch? Use it for low volume listening or for cheaper headphones - otherwise you'll be shaken to your boots...
My advice?
If you like good audio design (circuitry) and want something that is far better than nearly everything else out there - buy one and see for yourself.

I've had one of these for a year now and it only gets better. As others have commented, it needs a lot of playing in (200 hours or so), but it's worth the wait. With good quality headphones, the sound quality is clean and discreetly powerful, even when playing MP3s. The 'flat'(or normal) tone setting may be a little too flat if you like heavy bass, but I find it pleasantly neutral and good for a wide range of types of music. The 'contour' setting is great for beefing up older, unenhanced analogue-to-digital recordings. It is robustly made, particularly the switchgear and sockets. Battery life is very long, easily up to 100 hours in my experience.

Cool and sexy it isn't though, and it looks and feels homemade in a slightly unappealing way. If you're worried about appearances, it will be best to keep it hidden while travelling on public transport. Probably in a bag too, because it's a bit bulky to fit in a normal pocket.

Still, a five star rating from me, because it does the important stuff so well, delivering great sound and it's well put together too.
