Product Details

Bravo Audio V3 Mini Valve Class A Tube Headphone Amplifier with EQ

Looking for a high-quality headphone amp or to dip your toes in the world of tube audio? The Bravo V3 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 3-band EQ allows you to personalize the sound to fit your unique needs. A great deal of attention was paid to part quality on this amp, employing a well-regarded Electro Harmonix 6922 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 5.12" W x 1.73" H.

Bravo Audio V3 Mini Valve Class A Tube Headphone Amplifier with EQ
Bravo Audio V3 Mini Valve Class A Tube Headphone Amplifier with EQ is rated 4.1667 out of 5 by 6.
Rated 3 out of 5 by from The EQ ruins it!I've had the Bravo V3 for a couple of weeks now and have problems with the EQ in particular. It has no directions or markings or user guide to let you know where flat response would be. It’s not at the center detents as you would expect! I found a web review here (http://headfonics.com/2012/01/bravo-audio-headphone-amp-series-part-2-the-v3-ocean/) where the reviewer said it was in the down position. I disagree, mine had no gain and sounded awful that way. The sliders should be UP for flat response since a passive circuit cannot boost...only attenuate! At this position it seems as normal as possible, but the sound is lifeless and sterile. Bass is missing and lacks punch. All my headphones sounded better fed directly from my iPod Touch g4. I figured out where the EQ circuit feeds the main amp and tapped in there to bypass it. That made a world of difference! Now it sounded warm clear and dynamic. I would expect the EQ circuitry to affect the sound quality slightly, but not as much as I'm hearing. It's a pretty simple circuit and all seems put together correctly so I don’t believe it’s defective. As I said, the amp sounds great with the EQ bypassed, equivalent to the V1 model since they’re identical except for the EQ. I’m keeping mine, but I would recommend the V1, or the V2 instead. I also upgraded the MOSFETs from IRF630 to IRL530 and adjusted the bias which many others on the web have done, and it sounds great now.

Rated 5 out of 5 by from Outstanding little headphone ampI was hopeful but unprepared for the sound quality of this little headphone amp.  It is absolutely killer for the money and it competes with some $400 and up headphone amps on the audio retail market place.  The clarity is phenomenal.  Warm and enveloping sound.  Came with 6922 tube, was well packaged and protected.  My initial listening was done with a Parasound CD 1 CD player ( $4,500) which is a warm and detailed cd player.  After that I have also used a sonos fed via music stored on my  network and also satellite radio.  The headphone amp sounded great in all cases.

Rated 5 out of 5 by from Why did I even hesitate to get one?!As a seasoned young audiophile with picky ears, I have found very few affordable headphones that have groundbreaking performance- let alone headphone amps. Some headphone amps simply consider adding a little more power than the integrated amp in a phone or computer.I love that this design includes a variation of Class A amplification- I have class A/B JL amps in my car with Morel components, TRI amplified with class A/B towers at home and won't even get into the system I use to DJ. I always wait to buy something and research what I am looking at. After two months of waiting, and some electronics classes, I finally had to get this. I have three different sets of Bose OE and OE2 headphones because they have lasted well (one pair went through the wash and still functions fine!).Keep in mind, I know far better than to choose a product by the brand. That's a novice mistake. When I have done lasting stereo installs in churches, home theaters, houses, cars, and other mobile platforms over the years; the biggest thing that catches my attention is not the specifications on paper (which are always misleading due to varying power sources and parameters of testing), but actual conducted testing in person.In terms of an amplifier, solid state and digital MOSFETs are becoming the standard in everything- which is tolerable if the class of amplification is A, A/B, and in some cases D; But Class T and more compact are not oriented towards quality of sound reproduction, but a small form factor and are not within my interest.I personally want to start saving up for Analog, non solid state, class A valve/ tube amps for my headphones and home stereo. They are the past of electrical engineering, yet still the perfected pinnacle of quality audio amplification- only sacrificing efficiency and compact size which is not a concern to me. The amps I have in my car and my home stereo and DJ setup are all digital solid state MOSFET class A/B, and produce very satisfying sound with great power for their size and given efficiency, but lack the nature of analog amplification. A HUGE thing I hate about headphones (especially BEATS BY DRE) is built in amplifiers (active headphones)- which you pay hundreds extra for, and contain cheap compact class T or smaller digital MOSFET loaded amps- that are NOT oriented towards audio quality, but bastardize the sound of headphones just to make them louder and operate off of a weak battery. When shopping for speakers, drivers, or headphones, I always take into account the sensitivity, impedance, power handling capability, frequency response, if the cord is detachable, and of course resonation frequency and recommended crossover points and many other attributes that are pretty widely advertised; but my biggest concerns are: the magnetic ferrous material (is it neodymium, which is ~10x as potent?), is the driver passive and open to honestly accepting any amplification (or is it active with a cheap low quality amp?), what are the dimensions of the transducer structure powering the driver (is the voice coil a weak small cylinder or a wide strong one, effectively utilizing the magnets power?), how much quality engineering actually went into building the transducer and is the company very knowledgable or new to the market?I HATE when people make decisions on a product by the brand instead of the engineering that went into the product, but thats the way I was raised. I was not trying to conform when I gave in and bought BOSE TRIPORT OE passive headphones seven years ago. It was simply the engineering in the multiple tuned differential resonation bass tubes that give them the full sound that makes them unique, not to mention the powerful magnet, large driver, and extremely high quality voice coil in their earcup- complemented by the safety of a detachable cord, no onboard amplifier, and the comfy memoryfoam pads.After the purchase of headphones that I have grown to love, I needed something better than the built in amp on my Macbook Pro to use. This little champ was a contestant, out of many. What stood out to me about this one, was the three band equalizer. It isn't anything like my 60 band on my DJ mobile system or the 200 band on the sound processor in my car, but Jesus it makes a difference to have an EQ!! You can just about bend your headphones to sound exactly how you want them to. I am in school to eventually become a BMW master technician, and have years of school ahead of me. I am really looking forward to doing homework with my headphones and little tube amp, providing me spectacular quality listening to music and online lessons. Hearing class A amplification is comparable to discovering music all over again. If you are able to spare the money, and are looking into headphone amps under $150, I really don't know why you're still thinking. This is an obvious decision. :] Enjoy!

Rated 4 out of 5 by from Excellent! but not shieldedI bought this little guy to boost the performance of my larger headphones, and I must admit it certainly does that. My music collection became all new again. I was hearing things that I'd never heard before. Very open, very clear. It also has power to spare. If I turned it up as loud as it would go I certainly receive permanent hearing loss.I do have two problems with this unit though, the first is it's hot. So hot that you can barely touch it after it's been running for 10 minutes. This is something that I had read about and expected, so it wasn't a show stopper for me, but it is unfortunate it's so hot.The second problem is more serious to me. This device clearly has no shielding and is able to pick up all sorts of stray wireless signals and port them right back into the music. My main offender? My cell phone. Whenever the data connection turns on, if my cell phone is within 5 feet of the amp I get all sorts of hisses and fuzzes. I originally thought it was faulty, but by a freak accident discovered it was my data connection in my phone. This is very annoying to me as I wanted to use my phone as a source. This simply isn't possible with the amount of interference I get.Overall, it's a great device for the price, but be aware that there is a shielding issue and your cell phone could rain pretty hard on your music parade.

Rated 5 out of 5 by from Nice little monsterTube audio fan since the 1960s, anyone who does headphone listening needs this amp. Mine came with the Russian tube and drives the Koss PRO4A's with ease, the sound is crystal clear with the 3 band EQ a nice feature. Looks cool too, both on and off with a plexiglass chassis and exposed components.

Can this be used without a computer? Say just plug in an MP3 player for input & output to the headphones?

Asked by: Ahdeeo
Yes this will work fine for that application.

Can this headphone amp be used as a preamp with 1/4" to RCA jacks

Asked by: Wilber
It can--but the signal will be higher than the usual -20/-10db you see with a Hi Fi preamp. There is a volume control and that should pull the volume back so you wont overload the amplifier's inputs.

Can this be used as a preamp for the class D 320-334 with 1/4" to RCA adaptor ?

Will it pick up noise from an inverter 12VDC - 120Vac and used on my boat?
Asked by: Wilber
Voltage inverters by their nature can be noisy unless they are true sine wave [not stepped wave]. But, for headphones, the noise would be minimal. Your boat motor could add some noise--depends on the filtering.

Does this headphone amp allow different Tubs?

If this nicer tube amp costs more can you add replacement tubes or just a different tube?I see that the V1 and V2 both have a replacement tube option. I don't see a replacement for the V3 or the Ocean tube amp. Are there replacement tubes that can be used in the V3 and the Ocean?
Asked by: DefinitiveNut46
The 6922 is the direct replacement tube for this amp.
