| Older is better - D/A chip? Audioengr--The Nyquist Sampling Theorem requires the use of a reconstruction filter to remove ultrasonic images of the audio signal no matter what dac implementation one uses. This filtering can be implemented either digitally or by analog circuit... | |
| Does fair trade still exist Whether we call it price fixing or something else, it still represents an attempt by the manufacturer to disrupt free market competition among its dealers. Many manufacturers dread having their products become commodities and try to keep retail pr... | |
