There is relatively strong "beeping" on startup that could have been quiter. But it is not so annoying as other boards that "speak" on connect and disconnect events. The output is relatively clean from noises at idle - but this is evaluated in office environment so might change in quiet room. Power is good, so is the gain factor - it can be programmed with 2 dip switches. Output incuctors seem underrated for full power (50W) - but this is typical for low cost boards (one good class-D inductor could reach the price of this whole amp). CSR module is definately better than noname ones - so go for CSR.
