Based in Vancouver Canada and new to the forum/thread but not new to Nuprime, bought the IDA-8 and have been thoroughly pleased with it.
I want to buy an HD-AVA, but after doing some research, it seems it might be difficult to get a well written operational guide to help with configuring and utilizing all its functionality.
As a Nuprime dealer, can you help me get my hands on whatever you are using to support your customers who bought the unit from you?
Yes the HD series has been a challenge due to the initial platform, and design goals.
And you are correct that the manual is not as expansive as some.
But that is the extent of the documentation with the exception of a few posts and threads here on AC.
You might also find the additional info HERE
in the FAQ section under HT.
I think the units, which are on "close out" should best be viewed as a 2 channel Pre or Integrated, rather than a SOTA Multichannel solution.
The ESS SABRE Dac chipset is directly accessed via the USB input.
While the other digital inputs may also go through the 2 channel DAC, the circuitry is different and runs through a more extensive process to add Bass Management, Equalization, and Multichannel Processing.
So the PUREST Stereo Path is the USB. It is not "quite" an IDA-16 but quite close when used this way, still making it a great unit under those circumstances.
