HT-A9

[skazzy85]

Recently I have bought the HT-A9+SA-SW5. The pairing process was seamless and hassle free. Sound system was excellent. The only down side is the wire 2pin C7 cord was short as a standard package. Mounting to walls and need a centralize extension cord. That will make the wire expose ugly and alternative is to purchase 2pin C7 long wire cord from third party platform. Secondly, the amplifier wifi network config only support wifi 5. There are no wifi 6, wifi 6E. The latest was wifi 7 upcoming late 2023. I setup  2 units of my wifi system using Asus GT-AXE 16000 as main and AIMesh.
It would be great if Sony Teams re-modified the network config so as to support wifi 6E or even better wifi 7.

Overall, a great product.

Glad to know that you're enjoying it buddy! 
You can buy one of those cable management systems/bracket and it should help. 
And they do release update for the units, especially since it's new, however, don't think any update would help make it WIFI 6 or 7 as this is related to the chip inside the unit itself, anyway, enjoy it XD.
