I bought an SC-AK47 stereo about 18 months ago, and I haven't looked back since! The system is reliable, has an exceptional sound quality with output power to match (240W RMS, 360W PMPO), and IMHO looks nicer than the current SC-AK4x that's out.
The unit comes with an IR remote which controls pretty much everything you could want it to (except ejecting CD and tape, but why would you want to do that from a distance anyway!?). The remote range is pretty good, which is nice.
The speakers are bi-wired, which simply means there are two pairs of wires to each one, one pair for mid-range and high-frequency sounds, and one pair for the sub-woofers, quaintly described by Panasonic as 'Super Woofers'. The speakers each come with a grill for the front should you wish to use it (I do), and a reasonable length of speaker cable.
In addition, you get a loop antenna for AM, a trailing wire antenna for FM, a socket adapter for the FM antenna socket to allow ordinary FM coax aerials to be connected and a decent instruction manual.
There are a plethora of preset EQ mappings for you to use, together with the AI EQ, which allows you to tailor the sound to your own liking. There are also a couple of 3D AI EQ presets for a sort-of spatial effect, which works better in the Australian market where I gather the system actually comes with rear speakers too.
In concludion, the unit is easy to use, looks nice (especially with the twin-layer multicolour LCD screen) and produces nice quality sound. It's a winner!
