New Yamaha Amplifier. Excellent Price but Failed On Me

I purchased a Yamaha RX-V6A Home Theatre Amplifier to replace my 20 year old Yamaha that was still going strong. I wanted to venture into Dolby Atmos and take advantage of the HDMI facilities. Unfortunately it went into self protection mode within a month. I persevered with it for another five months and two services to reset it but it failed me yet again. Elite Electronics had it looked at by their repairer and it was decided to replace the amplifier. Their email communications were excellent. Having owned Yamaha products for years I think that this issue was a strange one-off. I am very happy with my new amplifier and I would shop with them again.
