Upon connecting the subwoofer (which is used to power the whole), we entent a constant 50 Hz hum!
After connecting the 2 speakers, then saperçoit quickly as shielding the amp is almost non-existent and that it easily captures all the parasites (eg radiation from the screen).
Add to this a complete absence of medium and fast distortion in the treble as soon as one increases a little noise. (The "64W Peak Power" are announced chuckle ...)
To top it all, the designers found it easier to place the inter / off at the rear of the subwoofer (whereas it would have been smarter to pair it with the volume control is within reach hand)
In short, a very big missed!
