[QUOTE="Zane Scheepers, post: 909630, member: 18657"] Hallo Pholo! :D Have a look on the internet at the output sensitivity of the Rotel pre-amplifier (or which ever pre-amplifier you have available) that you want to use with the NAD 2155 power amplifier. According to "hifiengine" the input sensitivity of the NAD 2155 is 1.3 [V]. Therefore, the pre-amplifier should have an output sensitivity quite the same as that of the NAD 2155 input sensitivity. Also note that, should the sensitivities differ greatly the sound will be too soft or distortion will be a problem, depending on input-output sensitivity orientation. :thumbs: Analogue distortion is somewhat "forgiving" but digital distortion is absolutely not an option. :O0: Here is the link to hifiengine: https://www.hifiengine.com/manual_library/nad/2155.shtml Hope this helps. :dance: [/QUOTE]
