You probably know that 600Ω is a "professional" standard and I'd assume that's one reason Stereophile tests with this loading.* It's unfortunate that a consumer needs to check for this type of compatibility in today's plug-n-play environment. It's not like this is some subtle sonic difference. ARC really should be more up-front regarding the (lack of) compatibility of their products with professional standards. At any rate, no ARC preamps for my friend - one lifetime.
*I've got old VOMs with dB scales where "0dB" is defined as the voltage that produces 1mW into a 600Ω load.
