The 3060 came out 3-4 years before the 3080? Hardly a good item for comparison, as they change the innards of every newer unit. Perhaps they didn't decide to use a cheaper power supply until 2019. Well, perhaps my 3080 was just a lemon for "long term" use, if you can call under 3 years long term that is. (As just at that time it started to die) At least for half of the time, using the double impact tektons at 4 ohms may have over taxed it a bit, though that was only on the main front channels and the 3080 specs clearly state that 4 ohm and even 2 ohm is acceptable. The rest were usually 6 ohm and once in a while an 8 ohm set here and there. Switching between elac, klipsch, kef, mission, rbh, etc. etc. etc. according to my inclinations at any given time. As I get tired of the same setup after certain periods of time. For the long term the 3080 felt taxing to me, as I use my audio devices a great deal more than any average listener. And I wasn't even using it the whole time because I was switching out my other receivers with it on a regular basis. Perhaps you are very fortunate to have the older model 3060 with the 24 bit ESS DAC instead of the newer 32 bit one. Newer is not always better. My older receivers have given endless amounts of bliss with hard core power for years and are still going strong. They are all rated at 10-30 watts less per channel than the 3080 and they all pushed harder and louder. Especially when using 6-8 channel stereo mode. - - - Just because you don't have any hearing memory that does not mean that no one else does. I used the same exact speakers for the "newer" Z9, played the same exact music and the results were horribly different. The earlier Z9 was so picky that I could only stand one specific pair of pioneer andrew jones tower speakers to use it with. The newer one sounded horrible with those same pioneer speakers with playing the same songs. The "newer" one sounds great with other speakers with some similarities, yet in a completely different way than my other one did. Doesn't make sense to me either but that is exactly how it is. Anyway, no sense in trying to explain it to an unbeliever. Whatever, That is my experience.
