Question about Yamaha A-S501

Also from our side: Yes, it is possible.

Hi Vortrex, yes, this is absolutely possible, if your TV has an optical output of course. Please also note that the amplifier cannot transmit video signals, you would have to connect this directly to the TV via HDMI. In addition, only stereo is audible here, so if you want a home cinema with surround, I would recommend an AV receiver. If stereo meets your needs, the A-S501 is the best choice. Kind regards Fabio

Would you recommend the Yamaha A-S501 for the KEF q550 speakers or is the A-S301 already sufficient?
Many thanks for your help.
