Pro-ject, a company that makes turntables has recently brought out a headphone amp called the head box. Has anyone heard it or know how it rates against others?
Ian: Try the search function. I'm not too happy about mine, and TimS (at least I think it was him) didn't like his unit very much, either. To my ears, even the old version of the Porta Corda does a much better job.
Opened the thingy: I found some Jamicon and Yaego elcaps near the power input together with two larger three-pin ics that looked liked 78xx/79xx power regulators, some smaller plastic caps near two ne5532p opamps, quite a lot of resistors that looked liked 1% metal types and two pairs of c327/c337 transistors per output. The two pots and the input selector switch didn't look very expensive, but I couldn't find the making. Soldering looked decent. The board itself has the trademark of Edgar (www.edgar.sk) printed on - so it doesn't even seem that Pro-Ject make this amp by themselves. Any idea, whether this is a well-known design?
