Very unusual streamlined design. Very light and fits easily under or over other equipment. Disadvantages include very hot operation that encouraged an external fan installation and some what flighty mode selector operation; it's a rotary selector. Thus said it sounds clean and solid. I found an interesting feature that I'm not sure is an intentional part if the design. It puts out an RF signal , FM modulated, in the international shortwave band aroud 10 mhz. I believe it was intended to feed wireless surround speakers.Will some one please advise.
