Transform your smart phone, mp3 player, DAP, tablet, or laptop music with tube tone that fits in the palm of your hand. This portable valve amplifier will take your audio listening to the next level while you enjoy vacuum tube tones everywhere you go.



Saviaudio's SA9227 and Texas Instruments PCM5102A are at the heart of our extremely hi resolution DAC valve amplifier. This DAC provides you with resolution up to 32bit/ 384kHz.



From IMS:

Walk into the lounge of any keen Audio Enthusiast and you'll see a Tube Amplifier at the heart of their system. Why? Quite simply because the old fashioned vacuum tube amps gave the best sound. So what if there was a pocket size tube amp that would give us back the rich audio quality our smartphones so badly lack?



The Hybrid Valve Headphone Amplifier gives us back the warm rich quality sound that was lost when transistors took over from valves. Plug it in between your phone or MP3 player and your headphones. Your music now passes though real glass tubes resulting in vastly improved sound quality. It will also boost the volume so you'll now have enough power to drive your headphones.



Amp Specifications

When designing the Valve Amplifier, our first priority was to get the best sound possible. Right down to the individual resistors we've chosen components to give the lowest noise and to be virtually distortion free. We've even hand measured each tube before assembly and matched these to be within 1%.

Tubes

Made by Raytheon, makers of the patriot missile and Apollo's guidance computers. These 6418 tubes are special: You'll find these same valves in some of the best studio microphones such as the Audio Technica's AT3060.



If you bump the amplifier you will hear a slight ringing sound similar to if you tap a wine glass, this ring is called microphonics and unavoidable with many small tubes. The ringing will die down quite quickly. It's not a buzzing noise but a pure tone. When you have music playing though the amp and you knock it slightly it will be hard to hear any ringing. When you turn the amp up full volume with no music and knock it the effect will be more obvious. This is how valves behave. The upside to this annoying phenomenon is the warm rich sound which valves deliver and transistors cannot.

The Best

by

It’s the best small headphone amp I have had. I’ve tried a few, a 300B Cary, a HifiMan Tube DAC and a Little Dot. This DAC Hybrid Valve Headphone Amp is GREAT! 



 Once again thank you. All the Best!
