Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: New technology coming from AN - oxymoron

"Using a NOS architecture does have technical problems but the impulse response is impressive and may give it a sonic advantage"

There is nothing remotely impressive with the impulse response of a NOS DAC. It is wrong. Period. It results in ultrasonic distortion products that may or may not be audible depending on downstream equipment. It does not result in crisp impulse response that mimics the original analog waveform that was recorded, because the analog to digital converter had to use an anti-alias filter to prevent gross distortion. The laws of mathematics dictate that this anti-alias filter will have poor impulse response when running at the 44.1 kHz sampling rate.

People who don't understand how digital audio works should not be using terms such as "impulse response". They should stick to what they hear, keeping in mind that they are listening to an entire record playback chain starting with microphones and ending with speakers.
