I have been both a hobbyist and a hi-end audio cona owner. contrary to the above, the best place to make changes is closest to the source, if not the source itself, 
I think your question is too general.
You need to be specific, which speakers and amp?
I'm 
Speakers VR4JR, Opera Seconda, B&W PM1
Amps Parasound Halo A21, Mono Vincent 998, Musical F M2SI. Thanks
"Speakers are the one and only thing that will make a major change for your system! Everything else is of secondary importance!"

Completely untrue statement.  A system can be shaped in many ways.  It comes down to what you are hearing and what you would like your system to do.  For example a preamp can add dimension, micro and macro dynamics, detail, extension, focus, separation of vocals and instruments, with more impact that some speakers can.  So can a better source DAC, ad amplifier.  How did I form my opinion, well easy, I have taken various components and placed them in various systems and the impact for the component has been the same major change.  The only difference was the speakers, etc.  In performing component upgrades, people were also able to hear the impact that they also can add to ones system.

Happy Listening.
