Very good product; Well packaged by the manufacturer and delivered in a transport box by Amazon. After unpacking we are surprised by the heavy weight of the unit. The power switch is located on the rear panel, which means it is difficlement available when the amp is placed in a cabinet; However, the standby is on the front of the apareil and, of course, on the remote. the buttons on the device are small and unobtrusive yet readily available. we can not say the same on the remote, a little too large; a little over a compacted version would have been desirable. Easy installation, connected with BOSE speakers Accoutimass; happiness!
