(I have corrected this post as to give the wrong impression) Having done further programming with the Buffalo DAC, I realized that the regi...

Just like phase noise in clocks, it is difficult to compare noise values among linear regulators because there is no common ground in specif...

Not an Arduino, but based on a cousin of the ATMega168 with built-in USB. Of course totally incompatible with the Arduino development tools....

Is is fairly simple to use Arduino to program a DAC such as the ESS Sabre32. After you connect the appropriate signals (wires) from Arduino ...

Finally got my copy of Bondy Chiu's audiophile recording from Hong Kong. It was sold out over Christmas... HQCD is a higher quality pre...

As extreme care has been afforded to reduce noise on Buffalo II, perhaps it would be also prudent to implement the I2C isolation solution to...

In the previous post we found that the Crystek oscillator used in the Buffalo II DAC is very good, better than the typical oscillator found ...

According the Brian in this post , the clock in Buffalo II is not only the top-of-the line product from Crystek, but a custom made model wi...

(Update, Nov. 2010: I've developed Arduino code to control the Buffalo DAC. Check my other blog: www.hifiduino.wordpress.com) TwistedP...

A reader sent me some measurements on the I2S lines with the latest driver. The first picture is with Fast Mode and the second picture is wi...

I'm going to attempt to use the WM8804 SPDIF receiver in software mode. A quick look at the datasheet shows that there are...
