I just added one to my cart so I guess they have more in stock. Doesn't have the S-Air receiver for wireless rear speaker amp. I have this set except I also have the S-Air receiver for the rear wireless speakers. System works perfectly. It syncs very well with my Sony Bravia TV. The speaker sound is good enough for my living room. I can turn it up very loud and still hear no distortion. If you run the setup app for the speakers then the center channel speaker is very weak, I adjusted it up quite a bit and now it is very balanced.
