I would like to use HD-AVA as power amplifier of my Marantz 1608 which has front preouts, because of the interesting ADA price.
So I am not interested in the AV section, but in the Stereo part of it.
In the amp comparison page, the Stereo components of the AVA are not mentioned (for ex. Op Amp + Half Bridge + Switching) and no picture of the inside in the product page, but in the amp comparison chart it seems to have the similar sonic features of the IDA-16.
I have seen that "It is the same amp section as the IDA-16." in this thread.
But what about these features of the IDA-16, are these the same?: "the Switch-Mode Power Supply (SMPS) technology. For thundering, authoritative bass performance, the IDA-16’s innovative supply and its Cross-Matrix Array (CMA) capacitor bank"
On top of that why is the sound stage better and the texture worse?
Many thanks, I am about to buy one of the NuPrime amps, but figuring out which one...
