Peter, is there a relativly easy way to raise the output voltage a bit? maybe to 3 volts?

That's even better justification for your under-the-radar marketing program.


Kudos. (And congrats on the Positive Feedback award! Good luck keeping up with the increased demand...)

You could experiment with I/V resistors, but their value rather depends on supply voltage: http://www.diyaudio.com/forums/showt...483#post173483

Other than that, you could try adding an active output stage with a gain.

Just want to say congrats on the 1k post milestone! What you have accomplished for you business is nothing short of impressive, and certainly encourages a lot of similar minded people to follow their endeavours in the audio business.

Now where is our promised buffer???

I was not under the impression you used any components in those areas but I had to ask after seeing the picture.

Oh yeah... because you would know, what size posts are the one knob Cardas speaker wire binding posts? I need to figure that out for when I buy spades. I think I am going to use the one turn things on my amplifier and speakers (FR125s horns I think I might build for fun).

Hey Peter,

Since I'm fairly new at this, I'd like your advice/insight on this component/chassis layout of your LM4780 kit.

It's in a 12" x 12" by 3" aluminum chassis. Any problems or blunders with this layout?

..Todd

Has anyone tried wall warts as the power supply on the DAC?

Such as a switchmode instead of the transformer and MSR860's or a 9VAC wall wart instead of the transformer.

Seems to work well in the SI amp and Charlize and wondering if it would work with the DAC.... (thinking out aloud )
