This discussion is pretty much dead, but still, here goes:
Opened it up, everything was inside, luckily I had an EU power plug available that fitted into the Bravo Audio power supply, so far so good. No adapter required so yay.
The unit itself is pretty clean and clean, no real complaints. Some things are slightly skewed (inputs and stuff) but I couldn't care less. There was a lot of plastic residue hanging from the sides of the clear plates (plastic strings from manufacturing the unit). Can be taken off by hand, no big deal.
Tube is intact, put it in the V3 and the blue LED started shining. The unit was not and has not been plugged in yet, this means that the capacitors still had some charge in them after about a week of shipping. I do believe this unit was manufactured quite recently.
After some time, the LED started fading. Takes a considerable amount of time though (after like 30 minutes it can still be seen in the dark). Plugged in the unit, ready to confront the HORRIBLE EMI or whatever everyone has been complaining about.
It was not dead silent, not even close. Plugged my phone into it as input and it still hummed. I decided to ignore it and focused on the sound. It sounded... better... in a way. Fuller, maybe warmer. I don't know what dem audiophiles can hear but the difference wasn't that massive to me. Dissapointed? Not entirely.
Fun fact: Touching one of the 4 screws at the side of the plate can remove some hum/hiss, something to do with grounding. You could touch some electronics but eh D: I'd rather not.
The moment I used my PC a lot of the hum disappeared. I do believe my PC is a better "grounder" than my phone is. It was only noticeably audible on low volume or high. But turn the knob 90 degrees so it's pointing to the left, it suddenly was (almost) completely silent.
Now, after some time with it, the hum on low volume is (again almost yet acceptable enough) completely gone. It's basically silent for as loud as it needs to go for me. Note that it's on top of my PC right now, not exactly EMI free. Put your phone next to it or on top of the power supply for some great hums and hisses though. I don't exactly have a lot of space to put it (I even have a router a bit over a meter from it).
The device gets hot, really hot. The tube itself is fine, but the heatsinks are hot!
This was tested with an HD558, not the best at all obviously. My AKG K7xx has been shipped though. Got a DAC incoming as well, might be important as the hum seems quite input dependent.
'fraid this discussion is pretty dead and doubt this will drop again, so down the archives this goes!
