Graham Slee Voyager Portable Headphone Amplifier

Graham Slee Voyager Description

Graham Slee Voyager portable headphone amplifier.  High quality headphone amp for driving dynamic headphones, ideal for iPod and MP3 portable audio listening.

Give your iPod a serious sound quality upgrade with the Graham Slee Voyager portable headphone amplifier. The Voyager is a truly portable headphone amplifier and is small enough to fit a shirt pocket! It has a similar "footprint" to the iPod Classic MP3 player, which can be strapped onto the Voyager for ultimate convenience. The Voyager amp connects using a supplied jack-lead and connected via the iPod's headphone out sounds remarkably good.

The powerful sound from the Voyager portable headphone amplifier gives an average (noticeable) 10dB boost in sound pressure level above that of most portable players. The Voyager portable headphone amplifier's fast wideband circuit assures all the sound quality of the source is delivered to the headphones, even when used with high performance sources up to studio standards.

Graham Slee Voyager Amp with iPod Classic

It is fully portable, powered by its own replaceable standard issue 9 volt (MN1604; 6LR61) battery (supplied installed), by a USB connection or alternatively by the supplied AC adapter. If left playing into headphones from a continuously looping music source, the battery can last 50 hours or longer. Usually however, battery life will last a number of weeks if the power switch is set to its other positions when not in use, or when being powered by USB connection or by its AC adapter. It does not recharge the battery - a rechargeable 9 volt battery does not have the capacity of a disposable 9 volt battery.

Graham Slee Voyager Reviews

Hi-Fi World, April 2008 - review by David Price:

It's notable for two things; its eerie smoothness across the midband and strong but supple bass.

Driven by 'the Hi-Fi World' iPod (Classic, running Apple Lossless) it produced very nice noises indeed, removing at a stroke the iPod's cold, steely, hardness and limp bass response. In its place is a warm, fulsome and naturally musical sound with nicely detailed treble that's as fluid as it is spacious.

In short: it sounds just like a Graham Slee phonostage!
