My apologies for the poor response earlier on your question. Here is what is going on in our converters:
Every D/A converter requires an analog low-pass filter at its output. This is to get rid of high frequency noise that is not correlated with the music signal. There are many different ways for how to design this filter. Most manufacturer make this filter very steep or sharp to minimize the remaining noise and to achieve best measurements. However, there is a price to be paid: the steeper this filter is, the more the sonic performance (i.e. musicality) is impacted.
Since the noise is not correlated to the music signal, it is like listening to music with your window open when you might hear a little the wind outside. Uncorrelated noise does not distract from listening. Therefore, we have designed our filter not to minimize this noise, but rather to optimize the sonic performance with the lowest possible noise and without impacting the listening experience. So now if you stop playing music and turn the volume up you can hear more noise with our converter than with others. That is normal and was designed to optimize the sonic performance.
By the way, will you come to the Top Audio show in Milano? I will be there and would be happy to discuss this in more detail with you if you like.
I hope this helps.
