[QUOTE="pwatts, post: 1158250, member: 146"] Hi-fi is the wild west without standards. In Pro Audio and broadcast there are specific standards to avoid this, plus lots of protection mechanisms should something still go wrong. If mixing and matching manufacturers, it's up to you to confirm a good match. Your preamp is too hot or your power amp is too cold, either way, yes there is a real risk of blowing your speakers with a heavy hand on the preamp. As to cascading preamps, sure this can be done but each setup will be different dependent on topology. Rule of thumb is high gain followed by attenuation, not the other way round but this by no means is universally applicable, especially in the extremes. If the DAC attenuator is poor, you will lose resolution and the extra gain from the preamp will not recover that. [/QUOTE]
