		<description><![CDATA[Designing this front-end for my amps has been harder then I planned. Part of the complexity is the time delays I need to add; my woodworking is not bad but it&#8217;s not excellent and decided I&#8217;d put the speakers front-aligned. This lead to having to delay frequencies so everything sounds right. Now, there&#8217;s no way [...]]]></description>

Well, seems it’s easier said then done. For the last week I’ve been trying to route my data bus (highlighted in the picture) to the FPGA (the left most IC). Considering I’m trying to do it on a two layer board I have no idea how I’ll do it. Feel free to leave a suggestion. [...]]]></description>

For space saving it would be the perfect enclosures to build the amplifier in it. Since Adam McCall got beautiful results I decided not to reinvent the [...]]]></description>

It will accept either SPDI/F coax and optical as input along with the more basic analog inputs. Every input module handle one input and will output an I2S [...]]]></description>

		<description><![CDATA[It&#8217;s one thing to build and amplifier, it&#8217;s another to build a pre-amplifier. I selected a CS4398 [PDF] as DAC; this chip has a differential output for both channels, an I2S input and up to 120dB dynamic range.
What&#8217;s nice is that Cirrus Logic made a very well designed evaluation board for this chip, the CS4398. [...]]]></description>
