I believe it was Mr. Hanson, from Ayre (I could be wrong) stated that the weakest point of most multichannel receivers is the volume control. Good volume potentiometers or resistor ladders, etc. are extremely expensive so only the cheapest models can be economically employed in multichannel devices where a lot of such devices are needed.

I have a headphone amp that uses as its volume control an Alps RK50 volume pot (4 gang). I know a friend who tried to buy that same pot from a supplier and was told he had to purchase at least 25, at about $800 for a single pot. I know that this is an extreme example, but, any decent pot will not be cheap.
