It appears maintenance costs Of 6SE r quite unfavorable. If you plan on using it a lot for stereo and home theater listening and including electricity costs it may reach as high as $100 a month and that's a lot.
I don't think people really factor in electricity costs although at least standby is very minimal but when active it's close to 150 watts it adds up.
So much for serving a planet which I'm not too optimistic about decreased carbon. The trend is extremely unfavorable kind of sad
