About the Special Edition Amp One: 


The GLOW AUDIO Amp One is a hifi classic, renowned for its smooth, detailed, and accurate sound and a fatigue free presentation. We are upping our game with the introduction of the GLOW AUDIO Amp One Special Edition

We have rolled about every tube combo imaginable before deciding on the Mullard EL84 and General Electric JAN 5670 as our upgrade choice for the Amp One Special Edition model.   

The Mullard power tubes add a body and depth, a creaminess and texture, that is hard to describe but easy to hear. 

The GE 5670 driver tubes provide the foundation ..... a clean, balanced, tonally accurate and somewhat dry first gain stage for the Mullard's to work their magic with.   

Of all the possible tube combinations available, we came to like this particular match up the best. We are confident you will like what you hear, too.  



NOTE: All GLOW AUDIO Amp One Special Edition models receive five hours of burn in and testing prior to shipping, so that you can be confident that your amplifier sounds its best .... right out of the box.  




The GLOW Amp One is a classic stereo tube amplifier design, with a twist - every GLOW amplifier has the option of being connected to your computer via the GLOW Audio DAC 1.3, a plug and play device designed to give you audiophile grade sound quality from any computer. This allows you to use your computer as a hifi music source, by streaming audio from the internet or playing music stored in your hard drive. (Note: As with our standard Amp One version, the GLOW Audio DAC 1.3 is being provided at no additional charge with the purchase of the GLOW Amp One Special Edition.)

The Amp One Special Edition model has the smoothest, silkiest and most detailed sound of any single ended tube amplifier at twice the price. 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.

Our promise to you: Our GLOW Amp One Special Edition will sound and perform as well as or better than equipment costing twice as much. If you don't agree, simply return within 30 days for a full refund of your purchase price.
