I have owned Joule preamps in the past including the 100 MKlll. I like the Joule sound and he makes fine preamps for sure. I have not heard the 150 however. I know the Joule would be a nice improvement over your Rotel.
I have owned the Dude for several years now and can say it will deliver the things you are looking for to a greater degree then the Joule. The Dude is a champ at bass and soundstage plus in many other ways.
The Dude will cost $4,000 new and you can find used 150's for under $3,000. Is the Dude worth another $1,000 - $1500?
If you can stretch up to the Dude with your cash, then yes it is. At least is/was for me :-)
Both offer a significant improvement over your Rotel
