I am looking at getting the 1070 ... but I have an unusual setup ....

I have a dedicated 2-channel passive preamp that drive my two front speakers (Maggies).

I will be taking the Front PREs from the 1070 and feeding to the passive preamp (I use the passive preamp to listen to stereo music from a dedicated source).

Will the 1070 heat up as much when the front two channels are not powered by it ?
