With no rules other than 100-130 wpc, maybe the original post needs to be updated with all the additions that were mentioned and maybe the Pioneer Black/Silver® unit(s) could be added. The SX-5580 is the same as the SX-1050 but in different clothes. Additionally, there are Sansui models that are similarly different in looks and model numbers but mostly the same as other models that are on the list. Don't forget the use of quad units in stereo. The Marantz 4400 is rated 125 wpc in stereo.
