I have just upgraded from a Sony Dav S800 total 350 watts rms to the above, but although I am very happy with the sound, it does not seem to be all that more powerful. On the S800 I normally had the volume set at around 10 (Maxium system setting 30 - 350 watts), but with the new system I have to have the volume set to between 16 and 20 (Maxium system settings is 40 - 1000 watts), so does anyone know why, when I expected to this to be the other way round. Also on the silver 1000 version the max system volume setting is 70. I would be grateful for any advice on the above. Thanks.
