In 2003 (seems like a million years ago) I purchased the Outlaw Model 770 amp with the model 1950. 10 years ago as I went to a 7.2 setup from 5.1 I purchased the Marantz 5005 from Outlaw. Everything seems to be working fine but I have been looking to replace the Marantz with the 976 but is it already outdated? I have no plan to go to an atmos system but is there anything else I am missing with a more recent preamp or the Marantz 7705 (to be used as a pre amp)?
