Summary: I initially had a Series I 321, and recently upgraded it to a Series II. For me, the 321 systems are great in principle, and until fairly recently, there really wasn't much in the way of competition in terms of simplicity and portability. With new competition from Sony and Denon, however, I'd say the 321 has become less compelling, and you'd do well to shop around a bit. That said, the 321 Series II is very nicely designed for what it is.
Summary: With hardwood floors and a lofted ceiling, running wires for a surround system was out of the question. The Bose 3-2-1 system was a nice alternative. Great sound (not quite surround sound) and stylish apperance. Very easy to hook up but a bit pricey.
Summary: I got these for the simple fact of not wanting to run wires all over my bedroom. The sound is great and the "surround effect" is plenty for my bedroom. Overall I'm satisfied with the player and speakers.
Summary: I bought this over the 5 to 1 system. that would rquire to run wires thru the condo. I have no problems audio response either treible and bass, for the small setting it work wonderful. I run the tv audio fro my LG lcd. It a wonderful system of no techie to run. I wish though it could be upgrade to blueray and hdmi. great for audio cds and the radio is good with external attenta.
