500+ Head-Fier
yes I have done that! But with a 'lesser' ADC. I am now using an ADC that is strictly for measurements using the latest ESS ADC with incredibly low noise and distortion.With the Pro iDSD in your signature would be great if possible !
DSD256 input vs DSD512
Not really using its built-in upsampler
Only the very, very best measuring DACs are its equal or better.
An iFi NEO IDSD (1.1 version with headamp) arrived today, so I plan on measuring them both thoroughly to see how they stack up.
One thing a lot of people don't account for, is just how difficult it is for the onboard logic in these DACs to keep up with the clock speeds above DSD256.
Is it AKM that says they cant guarantee performance characteristics at DSD512? Forgive me if it isn't AKM that said that, but I know a major company did.
Furthermore, one of the engineers on the iDSD Pro, Thorsten Loesch, has pointed out the same. That these super fast logic speeds can be counter-productive as they lead to more noise. Such behavior is easily seen in the measurements of the iDSD PRO. The highest SNR is at DSD512. DSD1024 drops SNR by a few decibels.
