The choice for an NOS or upsampling D/A Converter is purely subjective and a personal choice contrary to a previous post which is erroneous and disingenuous as well.
Some folks prefer NOS while others prefer upsampling; it's vanilla or chocolate. Neither is right or wrong.
The amplifier with regards to your choice of D/A Converters is, of course, irrelevant.
Also incorrect is the "whispiest insulated speaker cable" advice. Choose the speaker cable that suits your ears and system. It's that simple.
