I built up 2 x SE-SE to use as power regulators for the ackodac clock and AVCC, but I plan to try them out bridged for kicks before they are enlisted in the more boring job of keeping DC steady

I received word a bit ago that the packaged arrived at home. Hopefully, all is intact.

Looking forward to pics!

As a side note, has the large parcel for the NTD1 arrived yet? It should be there today.

Cheers,
Owen

Missed a few details there.

NTD1 is Owen's version of the pass D1 IV stage. There's a thread all about it on the digital line stage forum ...

Finally got my SE-SE board cased up... (I was lucky to snatch the last remaining assembled board ).

This year somehow I am pretty much into solid wood, so I had a friend mill a solid frame from Golden Madrona Burl... just big enough to house the assembled pcb and the headphone jack. Power comes from the PSU underneath which is covered by a rusty cover made of 3mm soft steel (was spraying that with salt water for weeks ). The tiny floating front panel is basically held by the headphone jack and lit from behind by an orange LED, signal wiring is solid silver with 5% gold (left over from interconnects) in cotton sleeving.

Being the proud builder I like this one a lot, especially since it delivers soundwise to boot! I am very much into tube headphone amps (transformer coupled C3G-SE or Aikido parafeed etc.) and so far sold all my solid state stuff after a while (my M3 recently went to the Netherlands), but "The Wire" is a keeper. Even this being "only" the SE-SE it has tons of power, is V E R Y neutral and has bass control bordering brutality. It is also suited for all kinds of music although it tends to be a bit less forgiving on lesser recordings. It also needs some more mileage and listening evaluation since I finished it just a few days ago.

Thanks again OPC for coming up with this tremendous little piece of eqipment!

love the rust! you arent worried about it just continuing to eat?

really nice juxtaposition of materials, but also of the amp itself to the enclosure, the thing is so brutal (I used this word regularly to describe this amp) and clean

by weeks how long do you mean?

Now that is an absolutely stunning implementation!

I really enjoy it when people step out on a limb in terms on industrial design, and then have the skill to pull it off. I like the natural look of the burl on rust, and I can't believe how well that machined burl enclosure turned out! It really is a work of art.

In terms of implementation, I only really have two comments:

1. If it's not too much trouble, take the top enclosure apart and twist the two input leads (signal and GND) together very tightly running from the RCA jack to the input of the amp on both channels. By tightly I mean about 6-10 twists per inch. It really helps with rejecting 50-60Hz hum from the transformer and also helps with the overall noise floor.

2. Although I like the look of the 1/4" connector for the power supply, you'll have to make very sure that you don't ever unplug or plug it in live. The contacts will short together and connect to the wrong polarities as it's inserted, which isn't a great idea. A 3-pin XLR would have been a better choice overall, and if you're tight for space, they make a mini and a sub-mini version of those connectors.

Otherwise, I really like what you've done with it, and I'm glad you snagged the last one! I'm sure there are more than a few of these sitting unassembled in bags all over the world, so it definitely puts a smile on my face when I see one brought through to completion with such a professional outcome.

Cheers,
Owen

Default Beautiful Rendering

@Stixx

Took me a few seconds to realize it, but that is one beautiful set of Computer Graphics Renderings.

Care to post a few pictures?

hmmm... this got me thinking.

I might start a separate thread where people can post pictures of any finished project from The Wire series. I could then run a little competition for best overall design with some prizes for 1st, 2nd and 3rd place.

It might encourage those with half finished projects or those who haven't yet started to, to finish up and post some pictures!

I have lots of goodies here, so it shouldn't be hard to come up with three pretty compelling prizes.

I'll think it over, and start a thread with some details. People who put the work into projects like the one shown above definitely deserve to be rewarded

Cheers,
Owen
