Nobsound Tube Headphone Amplifier

The Nobsound is a cool little tube based headphone amp.

It uses two 6J9 tubes for the preamp which are small pentodes. The amplification is solid state based.
It’s a great looking little package that shows off the glow of vacuum tubes while you’re listening to your music.

It is especially good for listening to vinyl records. You get some of the warmth back that is lost with modern day digital. Most older records were mixed with tube based amps in mind so you’re one step closer to the audio reproduction the producers and engineers of classic records had in mind.

Bravo Audio V2 Headphone Amplifier

The Bravo Audio V2 Headphone Amplifier
is a small, one tube amp that will help push a clearer and warmer tone to your headphones.

This amp uses a single 12AU7 dual triode tube so we can deduce that each triode is used for half of the stereo spectrum.

It has a cool look were you can see the circuitry but it’s still covered by plexiglass.
The Amazon product description for this amplifier describes it as “non-fatiguing”. At first glance that might not sound like high praise but once you think about it most things in life after a certain point are, in fact, fatiguing. This amp is not!
Also, you need a headphone amplifier with tubes in it. Ask your doctor, he’ll back me up on this.

It comes with a high-quality Shuguang 12AU7 tube and there are parallel 3.5mm and RCA stereo inputs
Gain control with Japanese ALPS potentiometer.
