@sgordon1 thanks for the support. To answer the first part, I do not have the time, or the money to test every combo. In cases where I do have the money, I’d like to know what others think hoping to put it all together and do it right. I have a set of speakers that my amp does not drive well. So I ordered another amp. Fun, costly and somewhat irritating. Maybe a sub would be the trick - too late, I ordered the amp.
Had I known how much I prefer the feel of speakers and sub over headphones I would have saved money and time there too. I didn’t need to spend what I did on head phones. A sub helps with that in my limited space. It also seems my speaker sub pair might sound better than what I can do for a few K more.
