Here are some pics of my M³:

The Knob is a "Star Knob" from the German company OKW. The red circle is illuminated by LEDs and the knob does not exceed the front panel.

That is a cool knob especially with the low profile

Im guessing you could have made it in a smaller case if you felt like it?

I wanted some distance between the transformer and the audio circuit. The case is 43,5 cm wide, so it has the standard hifi format and is easy to integrate in a hifi system.

rille2. Thats what I call a clean build!
Nice work.

...and welcome to Head-Fi!

Beautiful work, rille2. Super clean looking, and that knob is definitely an eye catcher. Neat!

rille2,
The knob reminds me of the Xbox 360 power button.
I love the attention to all the details.

Here another 2 pics with closed case. The perforated metal plate allows the heat to disappear from the case. The M³ produces quite a bit heat for a headphone amp.

Do you have photograph of the insite of this Amp?
Nice work

Oh jeese, I can't wait to build mine now! Nice work!

I finally got my Minified Pints into their cases......designed for the desk top rather than the pocket. They sound great, and now I'm anxious to start on my Mini3s. One new thing I learned.....some foam rubbers are conductive, and should not be used as pads under a PCB

 

[mb3k]

Wow, you're one of the rare ones that have the PINT working w/out oscillation!
Kudos, the casing is awesome BTW!

Thanks mbk3....I never had any issues with the pint when I built them last year. I used AMB's instruction sheet to Minify them; I used the AD8397 for L&R and the LM6172 for the ground channel; I installed all caps except C6; the gain is set to 6 on one and 11 on the other. I tested them at voltages from 9v up to 18v with my bench supply with no issues....I use Sennheiser 600 and 650 cans. With the two 9v batteries in series, or a 15v wallwart, the idle current is about 30mA, and the temperature of the 8397 only gets up to about 104deg F.

I have a Hornet, a Minibox E, and will be building at least two Mini3s as traveling amps, so I decided to case the Pints up as desktop units.

Same here. I've build a crapload of pints, and never had a problem, all confirmed with an oscope.
