Review: Clean & Pure Sound with Solid "Cool Factor" - The V2 on it's own is outstanding, the sound is very colorful, smooth & rich. The better the cans, the better the sound as you would expect. I use a older set of Bose headphones for now. I will prolly upgrade to something better in time. They have served me well for years now their time is coming to an end, BUT..if you want it a more full stage as I wanted. I linked it up as a pre-amp to a Fiio A1 Amp, in turn powers Micca Club 3's which are my main monitor speakers for my computer sound system, I also have a set of old Sony 3" satellite monitors I re-fitted with RS75-4 3" Reference Full-Range Driver's from Dayton & a 10" Kicker Comp Sub pushed by a Lepai LP-168HA for it's sub output. The Fiio A1 amp sounds rather nice on it's own, but paired with this as a preamp music really shines...giving me the beautiful near field sound stage I was aiming for. I tried many different configurations but in the end, the set up I have now gives me what I was after. A headphones sound without the need for headphones. I honestly don't think it would sound as rich & pure without this as the preamp. I didn't feel the stock tube it comes with was giving me the sound I thought it should be, so I swapped it out for a JJ Electronics 12AU7 / ECC82 Preamp Tube. In doing so, after the tube burn in time, it has really come alive the way I was hoping it would. Classical guitar almost brings a tear to your eye as if it were being played in front of you. Simply amazing. Bass isn't overly punchy, just deep & solid. Mids are richly enhanced & the highs accurately sparkle. It's size/thickness is comparable to two iPod classics stacked on top of each other with the tube popping out of the top. RCA input is on the right side (Use the RCA input, it's sounds better as apposed to the----> ) & AUX 3.5mm input is in the front, center front is the volume dial (not an ON/OFF dial), to the left of that is the 1/4" headphone jack. The ON/Off Power switch & 12V 3.5A DC power plug-in are in the back. (I'm thinking on upping the juice output a bit by using a 12V 4.5A power supply although the supplied power brick seems to do just fine for now). Overall it's pretty straight forward. The "bells & whistles" are it's AMAZING sound quality & visual appeal, it's got serious "cool factor" going on with it's soft "Blue Purplish" glow that separates into blue & red... It's not too obnoxiously bright. A Blue LED under the Tube (that makes the tube glow blue) & a red LED behind that. The heat sinks stay pretty warm to the touch but it hasn't clipped due to an overheating issue. Although I haven't had a need to turn it ALL the way up either. 1/3rd to 1/2 way seems to be just fine paired with the Fiio A1 amp also turned up to 1/2 way for my listening needs. I almost got the step up version of this (BRAVO Audio V3 Tube Headphone Amplifier) which also has a physical EQ added to it. But I went for this one for it's size & simplistic nature. Music should sound good as it is. Besides how often these days do you come across a media source that doesn't have EQ settings of some sort?! Review: I'm poor, but I want to be an audiophile! - Few things can completely change the way you listen to music like a tube amplifier. Bravo Audio has created a small, yet powerful, and minimalistic headphone amplifier in the V2. Being an audiophile is considered a luxury hobby, with headphones easily reaching the 5 digit range, amplifiers going even higher, and the whole host of other "necessities" to be considered an audiophile being out of the price range of most average consumers, audophilia is left to the stupidly excessive. But what about those of us who love music with a passion and want to listen to music louder and crisper, but don't have an absurd amount of money to drop? In comes Bravo Audio V2 to the rescue! Sitting at a pretty price range of around $50, almost anyone with the slightest hint or desire to try out a tube amplifier should be looking towards the V2. It is small, easily fitting on my desk next to my laptop. It's open design is very modern, and while it was most likely done in an effort to alleviate overheating, looks very cool. The slight blue glow from the tube looks like something out of a sci-fi high tech movie, and people are stunned by it every time. Sound wise, it's simply outstanding. With more power running into your headphones, music comes alive. Instruments separate and you can hear different locations of instruments within the music. Bass is bigger, treble is cleaner, and the mids feather out the two much better to create an impressively more concise musical experience. While streaming music or playing MP3s is great, to really get every ounce of quality out of your amp, look to find and download lossless music. Specifically .flac I do not have a DAC just yet, but I still want the best quality I can get out of my laptop, so I use a 3.5mm to RCA input cable into the amp, which I feel fills out the sound much better than simply a 3.5mm to 3.5mm dual audio jack cable. There is a slight and constant hiss in the background, usually during pauses within the music, it completely disappears when nothing plays for a second or two, and is mostly inaudible during the music. I feel this is more of an issue with the sound card and signal transfer through that 3.5mm to RCA cable than it is as a result of the amplifier itself. Thus, I refuse to take away a star just yet, if I get the DAC and see that the hiss is still audible, then I might decide to drop it one star. Another very slight negative is the tube itself, it's cheap and so is the sound it produces. It's not terrible, and as I described earlier, it definitely does an amazing job of separating music and making it much cleaner, and for most will do just well. I expected the tube to not be the greatest from how low the price of the entire unit is. But if you just spent money on something as excessive as a tube amplifier just to listen to music, "just well" is not good enough. The tube amp is great, don't get me wrong, but when I switched the tube to the Genalex Gold Lion 12AU7 Tube, WOW! Simply eargasmtastic. Bottom Line: -------------------------------------- Don't have enough money for an amplifier that's more expensive? Buy this one and you definitely won't be disappointed! ## Features - Includes high-quality Shuguang 12AU7 tube - Parallel 3.5mm and RCA stereo inputs - Gain control with Japanese ALPS potentiometer ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.1 out of 5 stars 401 Reviews | ## Product Details - **Item dimensions L x W x H:** 5.5 x 5.5 x 4.5 inches - **Voltage:** 240 Volts - **Manufacturer:** Bravo Audio - **Mounting Type:** Surface Mount - **Brand:** Bravo Audio ## Images ![V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier - Image 1](https://m.media-amazon.com/images/I/71TdJS91tPL.jpg) ![V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier - Image 2](https://m.media-amazon.com/images/I/61bF1at0SeL.jpg) ![V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier - Image 3](https://m.media-amazon.com/images/I/61B+iPmBGcL.jpg) ![V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier - Image 4](https://m.media-amazon.com/images/I/61xm-I1DnTL.jpg) ![V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier - Image 5](https://m.media-amazon.com/images/I/61VcKvcMoVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clean & Pure Sound with Solid "Cool Factor" *by C***M on November 22, 2013* The V2 on it's own is outstanding, the sound is very colorful, smooth & rich.

Buy this one and you definitely won't be disappointed! ### ⭐⭐⭐⭐ I just like to listen to music *by W***N on August 11, 2017* This review is actually a simple comparison of 4 different Headphone Amps. First, I want to be clear that I am not an audiophile, not even close. I just like to listen to music, any kind of music that I feels right. So, this review just what I personally think about these products, nothing professional. Here are the 4 headphone amps (the DAC I am using is Logitech 980-000910 Bluetooth Audio Adapter, it will cost $21.98 from Amazon. And I know this is probably not the DAC you want to buy, you may want something recommend from z review or one of the most popular brand Fiio. But honestly, when I compare to those DACs under 100 USD, I just cannot tell the differenc. And the good thing about Logitech is they are Bluetooth and easy to re-pair to other devices. As I said before, I am not even close to Audiophile, that’s why I can’t tell the difference) 1. Fulla 2 by Schiit: $99 plus $10 shipping, total $109. I know this is a DAC/AMP, and I know this is a solid-state Amp. But if you buy any of the Tube amp listed below, you probably will buy a DAC to pair with it, after you purchase DAC, the price will be very close. And all the tube amps I compared here are not real tube amp, they are all hybrid. That’s why I also listed Fulla 2 here. 2. SMSL T2 2X6J9 Vacuum Tube Headphone Amp: $59.90 from Amazon (Total with DAC $81.88) 3. Nobsound NS-08E Vacuum Tube Integrated Amp: $50 from Amazon (Total with DAC $71.98) 4. Bravo Audio V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amp: $66.98 from Amazon (Total with DAC $88.96) So now you know all the price, seems like all tube amps are cheaper. But…….if you bought tube amps, I am sure sooner or later you want to try tube rolling, please consider that’s also your cost on amps. That’s why I said the price of Fulla 2 is close to other tube amps. Price is the first thing I consider; the second thing is the power to drive headphones. I don’t have a lot of headphones and this review is not about headphones, so please don’t ask me any question about headphones. The headphones I am using here are Sennheiser HD600, HD6XX from Massdrop, Sony MDRV6, Sony MDR7506, Beyerdynamic Custom One Pro Plus, Audio Technica ATH-AD900X, Beyerdynamic DT 880 Premium 600 OHM, Beyerdynamic DT-990-Pro-250 OHM, Bose QuietComfort 35, Fostex TH-X00 from Massdrop, Skullcandy Hesh 2 Bluetooth, Philips SHP 9500S, and Monster NTune. NO, I don’t have Beats from Dre headphone. If you really want to know why, please GOOGLE. Some are cheap, some cost a bit more, some very easy to drive, some needs more power. Let’s say the volume knob is from 7 o’clock all the way up to 5 o’clock. This way will be easier for me to show you how every amp provides the power on the volume. Yes, I know the headphone amp drive headphone is not just about volume but also how well it controls. But again, I am not audiophile, so I don’t care about the tech issue and I don’t want to see a lot of numbers calculating here. All I care is how the music sound and how loud it can be. All 4 amps with DAC give you a good sound, but tube amps are a little bit warmer. You won’t tell the difference unless you compare them side by side. When using any headphone is under 250 OHM, you will love any of these 4 amps. They all do a good job. You won’t go wrong on any of it. So, money wise, just buy the cheapest one you can find. Any 300 OHM headphone or above, you need to start choosing. If you use 600 OHM, you can forget about #2: SMSL T2 2X6J9 Vacuum Tube Headphone Amp. You can cross it out from the list, and that’s what I did, I don’t even bother to roll the tube. On 300 OHM headphone, Fulla 2, Nobsound NS-08E, and Bravo Audio V2 all give you enough volume makes you headache if you turn the volume all the way up (your ears won’t bleed, not that loud), and I only need to turn the knob to 12 o’clock. But not SMSL T2, I need to turn all the way to 4 o’clock. On 600 OHM headphone, Fulla 2 and Nobsound need to turn to 2 o’clock to my normal listening volume, from 2 to 3 only gains a little bit, and from 3 to 5, it won’t gain any more (you can turn the knob and play back forward, nothing going to change). Bravo Audio V2 only need to turn to 1 o’clock to reach the same volume, and from 1 to 4, it only gains a little bit. And when you turn to 5 o’clock on Bravo, it did gain volume more, but it starts distortion, and I don’t like how the music sound like that. On SMSL T2, the volume is like someone whisper to your ear even you turn all the way to max, and you need to push earcup real tight to hear what they try to say, maybe good for training your listening skills and how sensitive you are to the sound, but not very good for listen to music. So, if you want to use 600 OHM headphones and you don’t want to spend a lot money to buy a High-end amp, then please choose Bravo. Now, I am going to talk about how much heat these amps will generate. Because I already cross out SMSL T2, so I only talk about the other 3. (If you really want to know, it’s the same as Nobsound) Fulla 2, you can put your hand on it or just grab it. You will only feel a little bit warmer than your hand. Nobsound, you can pretend it’s not hot and leave your hand on the case for a while and keep telling yourself it’s not hot, it’s not hot, it’s not hot……….. Bravo, you can put your hand on the glass part and do the same thing as Nobsound. But I dare you to touch the heat sink, it can fry eggs!!!!!! Why we talk about the heat here, it’s a safety issue. I don’t think you want to leave Bravo on when you go to work or any other reason that you need to leave your house for more than 3 hours, it’s kind of like you forget to turn off your stove when you left your house (a very tiny stove). That means you need to power on and off every time you use it and before you leave. This is not a problem to me, but you might want to know. Then the headphone jack, Fulla 2 and bravo are both 1/4", Nobsound using 3.5mm. Personally, I like the 1/4 better. Then the input, Nobsound only has 3.5mm audio input, Bravo has both 3.5mm and RCA input, I didn’t try to plug them with different sources and start the music at the same time, I just assumed that it cannot, but you are welcome to try it and let me know how it works. Fulla 2 has 3.5mm at front and USB input on the back. I like the Fulla 2 better here, I can just connect to computer and use it. Then the external power, both Nobsound and Bravo are using external power charger. Of course, you can carry a generator with you and make it portable. but I will just use it at home. Fulla 2 just use your computer USB to power it. But if you turn the volume over 3 o’clock, you will need external power. You can use either cellphone mini usb charger at home or battery bank when goes out. Then function, Nobsound and Bravo are headphone amps only, there is no other output. Fulla 2 can use as pre-amp, DAC, and headphone amp. I use Fulla 2 connect to JBL LSR310S then LSR 305 and it works great, and from different connection on Fulla 2, you can use headphone and speakers at the same time but control the sound from computer not the knob on Fulla 2. (By the way, when you plug in headphone to Fulla 2, it will mute the speakers. But Schiit Jotunheim won’t, you have to power off your speakers or unplug the speaker cables, that’s Schiit company try to force you do some workout, not just sitting there the whole day, thank you Schiit, Jotunheim is really a nice piece of Schiit.) On tube rolling, Nobsound need a pair matching tubes, and sometimes it will cause some problem if you didn’t buy them right. Bravo just need one. I can tell you that I tried a lot of different tubes on both tube amps and honestly, I don’t feel a lot difference between tubes. I think stock tube works fine on both tube amps. If you really want to try different tubes, then I suggest Amperex on Nobsound. For Bravo, I suggest Baldwin>Sctron>RCA. Again, I really don’t think you need to spend the money on tubes. These are not real tube amps, so the sound changing is not that much when roll tubes. But…….. again……, I am not an audiophile, not even close, so………what can I say. Finally, I can tell you what I choose, but that’s only me. I keep Fulla 2 and Bravo. One for portable (Fulla 2 with computer, not cellphone, and I usually carry a battery bank with me, so I can just use that as power supply for Fulla 2, or I just plug into computer. Cellphone I use Fiio E12), Bravo in my dining room, so I won’t forget to turn off the stove when finish eating. For the price these 2 asked for, you really won’t go wrong on any of it. Personally, I like Fulla 2 better, but I just can’t say no to this cute but powerful Bravo. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/1182247-v2-class-a-12au7-tube-multi-hybrid-headphone-amplifier](https://www.desertcart.pt/products/1182247-v2-class-a-12au7-tube-multi-hybrid-headphone-amplifier) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-17*
