Boys, boys, boys. The OP has firmly stated that he will not buy used and is not in a band. Furthermore, he wants to buy an amp to play bass at home. Moreover, he has stated he wants an amp he will never have to replace or move. He wants a minimalist and simple home "practice" amp, but with great tone and a generous amount of power. He is not looking for a cheap little practice toy, to wit he is states he will spend up to $1500 USD!
Why should he waste money or time on all of this excited over-enthusistic chatter when he can just go buy a nice combo at guitar center and really rock on out? They even deliver. He stated plans to remain bandless, eternally delighted with his combo amp, and never be even a little curious about the new latest fEARful killer, M9-clone micro, or whatever.

So chill. We are done here.
