Been looking for a simple case to take the Pi and Wolfson Audio board, this Camden Boss case from Farnell / Element 14 fits beautifully and looks neat. I think the side with the HDMI looks like a smiling face :)

With www.HandelAudio.com amplifiers, you'll never be "screwed"

HandelAudio.com amplifiers are unique in the industry for a minimum of visible bolts & screws in the chassis top. That’s not a fluke. Not an accident. It’s carefully planned.

The planning and engineering required to mount everything without a bunch of visible bolts & screws showing requires a lot of thought, ingenuity and some creative techniques to securely mount the components.

Indeed, that’s half the battle!!

It takes time. Time to think…plan…construct…test for strength and reliability.

But the results are worth it. When you buy a www.HandelAudio.com amplifier, you know that it won’t just sound spectacular. It will look spectacular too. It will have a classy aesthetic that, gentlemen, your wife will welcome into “her” living room. :) We like to call our amps “refined.”

In the next few days we will be releasing a new triode single-ended amplifier with a new spin on our classic oak base. As we finish up the engineering, the pics of the all  point-to-point wiring will show the care we take in planning, engineering and symmetrical layout.
We’re sure you will love the new look, so stay tuned….

Hi Greg, Good catch!! Thanks for letting us know. We contacted our webmaster and had him fix it on the website, to match the YouTube.

Thanks for watching the video. The amp sounds even better in person!

Does anybody know, how does it work? Very need user or - better - service manual! Does anybody has experience of maintenance?

Yes, i understand this is speaker controller. But i need details.
Thank you!

The Junction Field Effect Transistor (JFET) offers very high input impedance along with very low noise figures. It is very suitable for extremely low level audio applications as in audio preamplifiers. The JFET is more expensive than conventional bipolar transistors but offers superior overall ...

Also worth noting that you'll probably have to carefully match the JFETs if you want to use this circuit for 2-channel stereo. And the output impedance depends on the position of the 10k potentiometer and can run up to over 2.5 kohms.

 Had a play with the Wolfson Raspberry Pi sound card (http://www.element14.com/community/community/raspberry-pi/raspberry-pi-accessories/wolfson_pi) tonight. Currently up and running with Squeezeplug (http://www.squeezeplug.eu/) as software headless Squeezebox device.

Initial impressions are good, the Wolfson support in Squeezeplug is beta at present but works well, the audio output has to be selected in the setup and I've noticed a peculiarity where 192k audio only plays via the line out, not via headphones. 96k and below works fine on headphones, not yet sure whether this is a hardware or software limitation.

This certainly has potential, with some better PSU options, to be a good sounding and versatile media player for those of us still running Logitech Media Server and using Squeezebox devices.

I find it fascinating that we can buy hardware for so little that has the potential to play HD content, something that just wouldn't have seemed a viable DIY job before devices like the Raspberry Pi.

For playback only there may be better DAC only options, but the Wolfson card opens some other possibilities as the input ADC capability makes spectrum analyser or other ideas a possibility for measurement purposes.

Hey out there. This is the beginning of the Danish Active Speaker Design. (DASD)
This is the first test of the ART-753SP/DSP

It's developed by ANARTECH. It incorporates OEM product from miniDSP and B&O.

It's developed for the use with WERSI organ, seen in the picture.

It's containing the following drivers:
One 12 inc. Woofer/bas. 300W class D amplifier.
To 8 inc. Midrange/bas. 300W class D amplifier.
One ribbon tweeter. 150W class D amplifier.

I must say that the first test was amazing. Well noted that the drivers are new and haven't played 50-100 hours the sound was very smooth.

There's still a long road ahead, fine tuning and listening. The DSP board/software have a lot of settings and possibilities.

Considering that it's a PA active speaker, the sound is very HI-FI like. I.e it sound amazing :-)

I'm looking forward to show you the final edition, they will be in white, same design as the WERSI organ.

Please don't hesitate to comment.
