I have owned alot of gear over the years and something has always remained the same. Whether you use 1 or 100 watts, a more powerful amp has always sounded more natural and effortless to me.
I have owned the 509 and I prefer my e480 to it. It will do just fine for now... once you hook up something like the m900 you'll immediately hear what you are missing. At that point you will decide if what you are hearing is worth the $$$ .
