Help please with system upgrade


Novice Member
We own the following items,

Yamaha AV1 amp,

Bose Acoustimass 10 series ll home speaker theater system

SONY BRAVIA KE48A9BU 48" Smart 4K Ultra HD HDR OLED TV with Google Assistant​

With the old setup we connected with optical cable but now we have a new smart TV, will I still get full benefit using optical cable ?

Or is it best if I upgrade my amp and use a 2.1 hmdi cable ?.

Thanks Mike.


Welcome to the Forum.

You'll get exactly the same audio with the new TV, a maximum of Dolby DIgital 5.1 SD. Unless you have an Atmos set up then keep with the digital connection as it is more stable then HDMI ARC.

Unless you need, or want the new audio formats available, ie, Atmos then there is perhaps there is no need to upgrade the amp. A new will not give you better audio performance. That would come from replacing the Bose system.
