Looks like Radioshack wants feedback from DIYers. Any ideas on what we should lobby for them to stock up on?     Here's hoping that the Canadian equivalent, The Source, will soon follow suit.

I'm planning to build a passive preamp-- simple thing with just an input selector and stepped attenuator. It will have no active components and no gain. Though I think I will try adding Tangent's Linkwitz crossfeed (also passive) with an additional DPDT switch to optionally  bypass it...

Sorry if this is a dumb question. But this has been bugging me.   It is my understanding that speakers run on AC, and the oscillations are what enable them to vibrate and produce sound. Two wires to a speaker, with the current alternating between each wire, and hence neither one is strictly...

My computer has a built-in optical output capable of 24/96. And my DAC is likewise 24/96 capable, but will also upsample lesser bitrates internally. I have some hi-res music, but most of it is just 16/44.   If I understand correctly, the main benefit of upsampling on the DAC is reduced...

I am considering obtaining a linear regulated PSU for use with my Aune mini dac+amp. The Aune officially takes 12V-18V, but can go as high as 24V. Ideally, I would like it somewhere below 24V, to be on the safe side.   This is a used PSU I found for sale, and it has a fixed output of 24VDC...
