Thanks Amir.
But I would like to understand WHY does it measure that bad ?.......It seems.......in order to get such bad measurements, you almost need to make it intentional.
Perhaps I am missing something that you see in the measurements and I don't. On Amir's THD+N for power amp chart I see 17 models rated worse.
These include the Anthem MRX 520 ($1400), The Sony UDA-1 ($800) and the SMSL AD-18 ($140). I will never own the Anthem or Amazon, but I did own a UDA-1 and AD-18 and neither sounded horrible. The SMLS AD-18 is extremely popular with lots of happy, (clueless?) owners reviews on Amazon.
As I mentioned above, OSD designed it for purchase by installers for business or home integration use. Thousands of this type of system are installed every year by installers and DIY homeowners. The end users are not audiophiles but just people who want to hit a few buttons on a wall panel or smart phone and stream Pandora around the house. What matter most is that they work reliably and are quick to install and integrate with home entertainment controllers.
