Why not just fit the same components Owen used onto some Vero board, or better, Tripad board? It's easy enough to do.

Here are some I made for another project. They had to be 6.9 volts:

I was considering that as my last resort as I am not an experienced DIY'er. Maybe I will look into it more seriously. Thank you.

The heatsinking was done by the case the regulator fitted into.

If there was a next time I'd look at using more surface more components. With this project, on the non variable +5V regulators, I used just one surface mount, a tant cap which can be just about seen on the 3 regulators on the bottom right.

I could; more dull treble, less distinct and more 'rough', especially on some metal chimes and any sound with fast edges.

I was able to hear the difference when I unplugged the XLR to varnished solid silver to XLR lead as well. Was more expressive and cleaner, better pronounced 'highlights'. Seemed as if the treble had been turned up a bit.

Not vast changes, but ones worth having.

Finally gotten around to rectifying my [hopfully] final mistake from when I built my original The Wire se-se. I used a 10K Alps pot but didn't change the related resistors. I did remove the 1K resisters some months ago but never changed the 10k ones for 100K...

All done now and my word it's loud & still sounding ultra fine with the HD-650's...

Here's my cased up Wire SE-SE-SE-SE Balanced build. It's nothing close to what Stixx put together, but I'm happy with it. Ignore the knob; I'm having a bolivian rosewood one made to match the case side panels.

Nice build Mr. Rogers!
Very clean and classic... only the wiring inside can be improved some
How do you like the Khozmo attenuator? (I was thinking to use one in my built but then opted for minimal size.)

Thanks mate! I'm open to suggestions re: wiring. I didn't pull down the shrink wrap or tie up the routing yet; still thinking about the wiring routing. Apart from keeping power lines from output and twisting power, what else should I be tending to?

I like the Khozmo - a lot. It steps quietly, and I really like the 48 steps. It is big though :-)

Well done!
You shoud twist everything very tightly (not only power wires).
Also, I see the main power cables and the transformer are a bit too close to the attenuator. I would probably try to swap the position of the attenuator and the headphone output socket, if that is possible.

Also, your picture screams for a detailed comparison with the schiit mjolnir!
