I have a Marantz SR-47 amplifier (with a Marantz CD-38 compact disc player) which I bought about 8-9 years ago.
I just bought top of the range Sennheiser headphones (HD 650) (US$370).
My main interest is classical music.
Now I would like to know what level of quality is my amplifier (I can't find any info on the net), in order to know how much I am limiting quality of the sound of the headphones.
Would someone in the forum kindly help me.
PS I have the technical specifications of the amplifier if one needs them to answer me.
