Hi, we finally got a 4K TV for our lounge so I updated our Sony 1040 amp to a Yamaha RX-V581 which was advertised locally at a fair price. The Sony had a great sound but was ageing, the main reason I upgraded was the Sony draws around 40W on standby 24 hours per day when it has passthrough enabled. The Yamaha draws 2W on standby so that solves that issue. However I find I have to have the Yamaha volume way up high, I thought it was faulty for a start as there was no sound but I just didn't turn it up high enough, you need it up to half volume just to hear it, is this normal? Also finding it rather temperamental with network features such as Airplay and can't get any internet radio to work, is there anywhere with recommended settings etc for this amp? Thank you.
