Bravo Audio V2 Class A 12AU7 Tube Multi-Hybrid Headphone Amplifier
Is it possible to use this with a computer ? USB , Optical , 3.5 jack etc. ?? if so what adapters would be needed
Yes this will work fine with the audio output of a computer. This will accept a 3.5mm or RCA input.

I keep reading that this tube amp can be used as a pre amplifier. If so, can it be implemented into a a/v receiver setup to yield "tube sound" through tower speakers? e.g. : ipod/computer > DAC > Bravo V2 > A/V receiver (In this case: Pioneer Elite SC-75)
Yes if you were to use the headphone output on the Bravo amp as a line output. You will have to be mindful of proper gain structure doing it this way, but it can work.

Use as a phono amp?
I'd like to listen to my LP's thru headphones. Could this unit be easily mod'ed to incorporate a MM phono input?
Well, you would need an additional "RIAA" curve device to accommodate plugging a phonograph into your headphones. Many stereo amplifiers have a "phono" output/input. There are separate units as well. I will list some below.

How is the BRAVO V2 as a preamplifer only?
Anyone have experience with this as an AMPLIFIER only? Planning on hooking up an old onkyo m-5160 amplifier and using the bravo v2 as a preamplifier to power my arx a1b speakers. Also will changing the tube change the sounds of the whole product or will changing the tube only change the sound through the headphone amplifier output? THANKS!
The headphone amplifier is also a preamplifier. It is actually advertised by Bravo as being a preamp, too. I have been using it as a preamplifier with the APA150 and it does give it a "warmer" sound.

Can it handle 4 ohm loads?
Is there any precautionary advice against using this amplifier with headphones that have a minimum impedance of 4 ohms?
Unfortunately no, the supported headphone impedance is 20-600 ohms.

How one tube can be in both channels?
I don`t know much about tubes so here is my question:two channels amp with only one tube, is that tube works on both channels or is it just for looks. anyone tried pulling tube out and still have sound output? I`ve had car audio amplifier with 4 tubes installed just for looks pulling them out has no impact on sound whatsoever.
The 12AU7 is a dual triode tube.I suspect one triode acts as an input buffer per channel and the "Class A" mosfets handle the output drive.
