Graham Slee Voyager reviews
Also known as: Graham Slee The Voyager
Voyager Portable Headphone Amplifier
Inherent headphone protection from damaging DC currents comes as standard with every Graham Slee headphone amplifier.
Gives true music lovers the sound they expect – it allows you to hear the emotion and feeling in the recording rather than just the mechanics of bass and treble (boom and tizz is so false); presence, not to be confused with “the warm glow”; stereo width in which we don’t mean fat stereo which is smear!
Those who do not comprehend emotion and feeling will either find themselves in a learning curve where compelling lyrics start to jump out of the recording and songs start to take on the meaning the composer meant, or they will simply not “get it”. This product is not intended to give the quick “fix” of an AB demo. It is not for you if you judge music mechanically or by the bling looks of the enclosure.
The shirt/blouse pocket sized Voyager portable headphone amplifier makes music on the move a whole new experience. Capable of projecting an airy musical outside-your-head performance using good headphones, and with a source that’s capable of it, the Voyager portable headphone amplifier can even make cheap headphones sound good: its contour switch compensates for the limited tonal range of lightweight street-wear headphones making them sound like real hi-fi headphones. From the moment of your first listen you will never want to travel without it.
Running on a single 9 volt “E-cell”, the Voyager portable headphone amplifier has a long battery life: usually lasting a month of average usage at good volume levels – and on occasion 3 months! This is because it uses a low loss battery polarity-protection system leaving more power for your music. When at home or at work it can borrow power from your computer USB port* or be powered from its mains adapter (supplied). Laptop users on the move can also make use of the USB* power facility, thus preserving battery power. Rechargeable 9 volt batteries charged on a separate charger may also be used.
The Voyager portable headphone amplifier uses noiseless DC to DC conversion to increase the 5 volt USB voltage to 9 volts ensuring no loss of level when powered from USB.
Stereo input and headphone output are on high quality Jalco 3.5mm jacks. The volume control is a high quality all metal Alps miniature “velvet” potentiometer of similar construction to the Alps AC27/30 often found on really expensive amplifiers, but a whole lot smaller. Switches are also by Alps – known for their precision. A clear low noise red LED warns you when the Voyager is switched on, helping you to conserve battery power.
The “no-bling” Voyager portable headphone amplifier case is made of hard-wearing precision machined textured ABS, featuring a black and silver anodised aluminium fascia plate carrying the necessary functional markings. A clip on cover securely holds the battery within its durable foam lining.
Each Voyager portable headphone amplifier is individually hand built in Britain by time served engineers and fully specification tested to ensure perfect operation. The circuit uses conventional through-hole non-surface mount components to help achieve its excellent and airy sound quality making it unique amongst miniature headphone amplifiers.
