Headphone Amp Photo Gallery

Some projects just lend themselves to extra effort. This is not complete, as I am waiting on a few more parts, but since the case was so nice to begin with, why not add brass? The DIY Audio case is excellent for enhancement. I want to add a brass disc for the headphone jack as well. Yah, I know, I am somewhat tempted to do the sides as well.

Given the right time/day a horse race is inevitable for me comparing equipment. Especially in this case, where two of the products are the same brand and model and the only real change is the op amp used in each. The other two amps are important not only for comparison, but as a sort of reference of where we are coming from to begin with. There are some complications that arise here, as the 4 unit are not hooked up entirely the same. The Xiang Sheng for example is the DAC being used to feed the two Whammy amps. The issue is that one of those outputs is tube and the other is SS. As much as this may considered a non starter, I was surprised at how little the differences were. Mostly in the top and the difference in actual output of each is very slightly different. That is one example of differences. In spite of that, the sound differences of each amp are mostly splitting hairs to me except for the Xiang Shang, whose sound is quite a bit brighter than any of the others.
Give me some time here, as I have only be able to set up for output levels of each amp and haven't done serious music listening. Um yah, at least one of these will be for sale. And yah know what? Another set of headphones for comparison would be benefit too. Let the games begin.
