"What do I like about the GLOW Amp One? Pretty much everything...
...quite simply I have never heard these recordings sound more real...

...a Hi Fi epiphany."

A hand crafted stereo amplifier featuring the purity and realism of tube audio. Get the sound quality you've been missing, with the simplicity and style you want. Meticulously designed to please the eye and the ear, at a price you can afford.
The GLOW Amp One is a classic stereo tube amplifier design, with a twist - every GLOW amplifier comes equipped with a USB input so you can use your computer as a hifi music source.
The Amp One has the smooth, silky and detailed sound for which good single ended tube amps are famous. If you have never heard a high quality tube amplifier, prepare to be startled by the subtle musical details the amp reveals. By design, single ended tube amps are low power, with high resolution.

Matched with efficient loudspeakers, the GLOW Amp One can produce the most natural sound imaginable. Just connect speakers and hook up your computer via the USB port, or your CD, iPod, DVD or your television via the RCA input, and enjoy your music as never before.
Or, with the 1/4" headphone jack, use the GLOW Amp One as a headphone amplifier, and experience an incredible level of realism and detail.
Our promise to you: while our GLOW Amp One sells for hundreds, we are confident it will perform as well as or better than equipment costing thousands. If you don't agree, simply return within 30 days for a full refund. Available at our special introductory price for a limited time only.

*POWER TUBE INFO: European EL84s differ in design from their Chinese and Russian counterparts in one important respect: On all European manufactured EL84s, pins 1 and 2 are connected together inside the tube envelope. Chinese and Russian EL84s do not internally link the pins 1 and 2. Therefore, when a European manufactured EL84 is plugged into the '09 GLOW amp, the additional connection within the tube envelope in the European design is likely to cause premature failure of the tube.
For the above reason, it is highly recommended that you NOT use European tubes in the 2009 Amp One, as you will likely permanently damage your tube and possibly the amplifier. All Russian and Chinese manufactured EL84 tubes are compatible with the Amp One.
