Product Details

Bravo Audio V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier

Looking for a high-quality headphone amp or to dip your toes in the world of tube audio? The Bravo V2 headphone amplifier will let you do both! Smart, modern aesthetics and a small form-factor mean that this amp will find a home on any desktop.  A great deal of attention was paid to part quality on this amp, employing a well-regarded Shuguang 12AU7 tube, Japanese ALPS potentiometer and Chemi-Con capacitor, and numerous other high grade parts.

Signal input is through either RCA or 3.5mm stereo jacks. The output jack is 1/4" stereo, but an adapter is included for those using headphones with a 3.5mm plug. A 24 VDC 1A switching power supply is included.

Why Tube Amplification?

Many audio experts believe that technology is just now catching up with the sonic benefits offered by "old-fashioned" tubes. The simplicity of tube circuitry contributes to reduced parts counts and greater sonic clarity. Tubes use far less (if any) negative feedback compared to transistorized amplification circuits. If and when tubes do overload, their subjective sound quality is often preferred to the breakup characteristics of transistors. Although glass vacuum tubes appear fragile, they are robust electrically. They tolerate high peak voltages, and also withstand longer-term overload conditions better than their solid state equivalents.

Specifications: • Power requirement: 24 VDC • Input sensitivity: 100 mV • Input impedance: 100K ohm • Supported headphone impedance: 20 ~ 600 ohm • Gain: 30 dB • Frequency response: 10 Hz – 60 kHz +/- 0.25 dB • Dynamic range: 84.6 dBA (300 ohm), 89.8 dBA (33 ohm) • THD: 0.016% (300 ohm), 0.45% (33 ohm) • Dimensions: 3.11" L x 3.11" W x 1.73" H.

Bravo Audio V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier is rated 4.5312 out of 5 by 32.
Rated 5 out of 5 by from omgFind out what your headphones are really capable of !! I have always loved the warm sound of tube amps and this little guy stands up with the best of them. Also works well as a pre amp with gain control. Highly recommended and with stereoscopic equipment I rarely rate this high!

Rated 5 out of 5 by from My first headphone ampBought this to pair with the classic Sony MDR-7056. As advertised, both exhibit a neutral, natural sound that really emphasizes the music. No exaggerated bass, shrill treble -- just music. A nice combo when you realize I bought both for about $150 total. Listening to Miles Davis right now!!!

Rated 5 out of 5 by from Very coolRead the reviews. went to the mod web sites did the mods.found some new old stock tubes GE, Sylvania,Raytheon, Hammond. each adds a little different character. found a little cross talk through the heaters.Cut heaters out of the circuit powered them from a separate 6v wallwort power supply. cross talk gone! Been using on a professional30,000watt pa system as a line driver. Adds another dimension to the systems sound.Still doing some testing. With out it system sounds great, with it system sounds great, remove it system sounds better with it. It just seems to add a richness and depth found only in the high priced studio pieces. I am very pleased with the outcome.Use it always.

Rated 5 out of 5 by from Maybe the best audio dollars ever spentPair this little amp with a pair of Grado SR-60 headphones. You're way under $200.00, and the result is hard to believe.

Rated 4 out of 5 by from great piece..... butRight out of the box this unit sounds good but can be improved with better tubes than the stock one . I tried a JJ 12AU7, which was good , A Baldwin 12AX7, which was better, then an RCA black plate 5963 ( slightly lower voltage 12AU7 ) which was best . The input started shorting out on the 3rd day so I pressed the 3 exposed jack rings down, checked the input collar tightness and sprayed Craig's De-Oxit inside the jack. Works properly again . The on off switch feels very light duty and as noted by others there are some design flaws regarding the 25volt cap and LEd location. I would have been happy to pay a little more for a design without these flaws as this is a nice sounding piece of gear

Rated 5 out of 5 by from Best $55. ever spent.I have to say it was hard to believe all the incredible things everyone was saying about this tiny tube headphone amp . There true . For the $55 I spent on this little wonder , I don't think I have ever been more impressed , or pleased .Now its hard to believe that incredible sound is coming from that tiny hand full of parts. I am hearing things in the music I have been listing to for years that I never heard on the same CD . The full robust richness and fine intricate detail is so pleasing to the ear , I have a hard time turning it off , just one more song" .If you don't have one yet , get one or two , before they go off sale . If you already have something that sounds better , you paid a lot more than what this amp cost .This just could be the best thing coming out of China today !

Bravo Audio V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier

I assume that this tube headphone amp is for one channel and that two are necessary to build a system. Darwin

This is a stereo amplifier.

Is there a manual available for the Bravo V2? There wasn't one packed with the one I just bought.

Is it possible to use this with a computer ? USB , Optical , 3.5 jack etc. ?? if so what adapters would be needed

Asked by: Kenneth S
Yes this will work fine with the audio output of a computer. This will accept a 3.5mm or RCA input.

I keep reading that this tube amp can be used as a pre amplifier. If so, can it be implemented into a a/v receiver setup to yield "tube sound" through tower speakers? e.g. : ipod/computer > DAC > Bravo V2 > A/V receiver (In this case: Pioneer Elite SC-75)

Asked by: ScreaminDemon
Yes if you were to use the headphone output on the Bravo amp as a line output. You will have to be mindful of proper gain structure doing it this way, but it can work.

Use as a phono amp?

I'd like to listen to my LP's thru headphones. Could this unit be easily mod'ed to incorporate a MM phono input?
Asked by: SSCpal
Well, you would need an additional "RIAA" curve device to accommodate plugging a phonograph into your headphones. Many stereo amplifiers have a "phono" output/input. There are separate units as well. I will list some below.

How is the BRAVO V2 as a preamplifer only?

Anyone have experience with this as an AMPLIFIER only? Planning on hooking up an old onkyo m-5160 amplifier and using the bravo v2 as a preamplifier to power my arx a1b speakers. Also will changing the tube change the sounds of the whole product or will changing the tube only change the sound through the headphone amplifier output? THANKS!
Asked by: AUDIONOOB1
The headphone amplifier is also a preamplifier. It is actually advertised by Bravo as being a preamp, too. I have been using it as a preamplifier with the APA150 and it does give it a "warmer" sound.
