Thought I'd put a little light on this modest preamp you can get for 50 bucks or so. I find it practical to use mp3-players as sound sources, and sometimes their output is far from the 1-2 volts most headphone amps require. So this little device comes in handy for what it is: a preamp. I'm gonna use it as a step-up to some of my headphone amps, and so far it seems to work. When tubes are burnt in and tested I'll report about function and sound.
