@AIYIMA You have the possibility to create a reference product for class d amplifiers if you build it with quality components but without making it a kind of All in One (bluetooth, too many connections etc...) I personally hope in 2.1 with precisely selectable frequency cut, headphone output, pffb, better op built in Power supply. I think it would become a reference product in the price range.
The marketing experts are you, but in my modest opinion it would be better to make it a different product even in the name (for example A09 rather than A07 pro) or for those who have already purchased A07 it might seem like a mockery ...
I think like Vict0r, maybe with subwoofer output and other rca inputs it would be perfect, and if you can also set the motorized volume with the remote control to raise and lower the volume it would be great.Another vote for no dac, no bluetooth, no bells and whistles. Just a high performing power amp would do. A dedicated subwoofer out would definitely come in handy, though!
It should be launched at the end of the month, but it will take a month or two for Amazon to arrive.
International safety regulations include Class II for mains connected devices that don't require a safety earth, and would be acceptable if followed. What we've seen in some of the photos are devices that don't have a safety earth connection, and don't respect the greater insulation / air gap requirements to meet Class II. Devices like that will be called out as being dangerous.Also any product with built in High Voltage (110 or 250 volts) Power Supply needs to be earthed and should really meet the international safety regulations. The advantage of an external supply is that you don't have to meet the high voltage regulations. Some of your competitors - even though they use a three pin plug with an earth, only connect the two live wires internally. This is just waiting for an accident to happen.
Really want to replace my nad d3020, which is used with TV:
1. Fiber coaxial to connect to TV spdif-out
3. 2.1CH, but not my main request.
7.1. - "12 v trigger in", currently i am using converter 5v USB to 12v converter to trigger nad d3020, so it starts when TV in switched ON, and turn off when TV is turned off OR turn on|off it by signal in fiber.
7.2. - IR learning to control it from TV remote (in my case VOLUME+- is more than enough).
