Audiophile•Bravo V2 Headphone Amplifier
Sorry, I no longer have the Bravo V2 amp I bought way back when. It's gone. If you want help troubleshooting, I'd recommend drawing a schematic that shows the circuit with your mods, and showing the voltages you measure at each node. The 12AU7 heater should be as close to 12.6V as you can get. It's OK if it's a bit low, like 12V, but I wouldn't run the heater higher than 13V, as that would be likely to shorten the life of the tube. As I...

I was looking at the O2 amplifier (not on Massdrop though) and was wondering if I'm using my lgv40 as the source do I need a DAC AMP or will a regular amp better since my phone's output bitrate is 32 bit whereas the DAC AMP is 24 bit also I'm gonna plug it into my wall in my apartment here in the US so 110 volts adapter or 220 volts adapter ? Also since I will be using the 6XX by Massdrop and Sennhiser what gain option should I choose for them 1 and 3..... 1 and 4..... Etc.

Hello all, first of all thank you for all the info about this amp and all the mods. I´ve made all the mods (changing the mosfets, changing the capacitors for high grade audio nichicons and other mods on this website rockgrotto.proboards.com/thread/11555/bravo-v2-modifications-2017) besides power supply filtering and some of them that are more complicated. The last one I did was the bias adjustment mod, replacing the 3k to 1k resistance and...

So I bought one. It's as expected. Not exactly hi-fi. Compared to my Objective 2 amp, this Bravo V2 sounds a lot more aggressive in the upper mids. Low impedance (50 ohm) headphones playing straight from the PC line out sound less bright. But this amp is kind of cute. This amp does sound better driving high impedance headphones, but still very colored sounding. Its bright and aggressive character remains, just less apparent than when...

This is a great little starter amp. I did quite a writeup on mods and different tubes. You can find it here: http://www.head-fi.org/t/671688/bravo-v2-review-tube-rolling-mods-coming-soon Also I did a comparo on the homebrew grubDAC/Bravo against the Schiit Magni/Modi. It can be found here: http://www.head-fi.org/t/676709/built-vs-bought-modded-bravo-v2-grubdac-schiit-magni-modi-comparison-and-review

Audiophile•Bravo V2 Headphone Amplifier
I was thinking of building a headphone amp based on a circuit like the one on which the Bravo V2 is based. Being kind of lazy, I just bought this version of the Bravo V2, instead. I'm comparing mine to an original version Objective 2 amp, which I built up from a PCB I got directly from NwAvGuy. So, what do I think of this Bravo V2? 1) Its output impedance is too high. It loads down trying to drive my Fostex T50RP headphones with 60 ohm...
