I also received yesterday the Sony A5000 at the incredibly low price of 349 euros. I have a Sony TV and a PS5, everything automatically connected very easily. The sound is crystal clear and very immersive, as if I was listening to a live jazz piece that I tried. However, at high volumes, the absence of the Sub Woofer is noticeable.
I am now looking for the Sa-sw3, but its prices are high, around 500 euros. However, I believe it is necessary, so if anyone can help me find it somewhere cheaper, I would appreciate it. Thank you

The bar is worth its money. If you have a Sony TV, it does everything automatically (Update). If there is also the possibility to purchase Sony rear speakers and subwoofer, you go to another level of sound. Yes, it's a lot of money, I know, but there are no cables.
Update 31/8/23. First, the bar was purchased, the difference in sound is great, rich full sound with details, even though the TV is Sony XR which has good sound on its own, the bar enhances it and adds the bass that it lacks. Then I added the SA-SW3 200w subwoofer, a big difference in sound-bass. You enjoy watching movies. You can't go above 55-60% volume, the neighbors will chase you, and the subwoofer is at max 8 out of 12 volume. These two should be sold together.
Update 27/10/23 I added the SA-RS5 rear speakers (yes, they are very expensive but) okay, the sound is amazing, you hear sounds from everywhere as if you are inside the movie. You have two options from the bar, with optical effects or without, and the rear speakers and subwoofer give you a different sound. For purchase, search a little more and with a little patience, you will find them for 100-150€ less in price per piece. As a final result of sound, you will not regret it.
