The plant was bought for a second living / guest room. But it is good for all. Unfortunately, from the set volume 10 (read the display) permanently switched on the device fans. The sound is so impossibly high and loud that the aural excitement already severely compromised. To bad, the system provides for the price, good facilities and a good sound. Why, however, fans must be installed in the parts I do not understand. So much power electronics is not plugged into the devices, as that one could not dissipate the heat by convection. A good device to death engineered! Pioneer has attended better!
