Ok fellow audio lovers, we have a new toy to show off! We have seen a number of solid state dac-driven amps, including a few that support USB for laptops and computers. How about one that is tube-driven? Bravo brings you the Bavo Audio V2 Amplifier to do just that.
This device supports both RCA and 3.5mm (line-in) stereo inputs, so that you can connect it to just about anything. Your laptop, PC, iPhone or the stereo you already have sitting around. Plug your headphones into this amp and you are good to go with built-in gain control. It supports 1/4″ out for your headphones and comes with an adapter in case your headphones are 3.5mm.
When combining this with your source of audio, you quickly find an enriched volume of sound working its way to your ears. The mid-highs on up sound very good. There is a noticeable crisp quality that leads to a quick smile. The mid-low on down range however can sound a little muddy at times.
We noticed there was a bit of noise during quite moments that is caused by the unit’s power supply. This can happen at times with tube amps, and for the price, we kind of expected it to happen (to be honest).

It looks intimidating while it’s on and lit up and causes a lot of looks from those passing by. The design is sleek and nice to the eyes. It looks exactly how it should…a miniature tube amplifier.
The tube that it comes with can be swapped out with any 12AU7 vacuum tube, and if you can find a good deal online (such as eBay), it would be worth it. The tube it comes with (Shu Guang 12AU7 tube), although sounds great, isn’t exactly the best. Again, it’s great for the money, but you will want to upgrade the tube for sure.
It is recommended that you modify it a little with additional heatsinks/fins to help spread the heat a little more. This little amplifier really gathers some heat and can be quite hot to the touch (in fact, we would advice that you avoid touching the metals on it as it may/will burn.
There are also a few other mods that can be done on these, including one to suppress the noise from the power supply. Once you get one of these little amps, you can research them online to see which ones you are most comfortable with (some require playing with wires/solder). These mods are not necessary but can bring about better audio and heat distribution.
For the price, it’s a great little amplifier, and looks just as awesome as it sounds. The lower range sounds a little muddy, but swapping out the tube with something better could very well assist with this. If the tube wasn’t exchangeable, we would have voted it down quite far. We were impressed with it and decided to give it a 7 out of 10 score. It’s not quite “audiophile” quality, but *once again*, the price is right. If you are looking for a nice solution to make your laptop or other mobile device sound better while sitting in one place, we can recommend it with confidence.
