Stewie, For the sake of argument, IMHO if you have no reference to what 'better' means (to you) how will you ever know when to stop up-grading. There is always going to be something 'better' on the horizon even if in reality its only different.
IMHO, if I didn't make it clear, if you don't have a goal, how do you know when to stop? When you run out of money?
I'm always concerned for folks who ask for reccomendations for new speakers (or anything) but are unable to articulate what they don't enjoy about thier present speakers or their system. I've been there, done that, and never was really satisfied until I came to an honest assessment of what I wanted to hear, not what some one else said was what they loved, was SOTA, etc. Arriving at that stage it was much easier to read opinions and get some value, and sometimes direction, from them.
BTW, for those folks with defined audio expectations, and who have developed critical listening skills, I think I would disagree with you that the electronic's are not so important. IMHO, once you have found speakers that 'can' satisfy you in your room after they have been properly set up, the electronics are going can make or break real long term 'system' satisfaction.
A good analogy is, perhaps, represented by the fellow that auditions say your VSA's at a dealers or friends home. And thinks how magnificant they are. He get them home and is are disappointed. Why?
Well, assuming you have the same room, so to speak, and you have carefully set them up, guess what - its the electronics that are making the difference.
The speakers are what they are, and IMHO, it is often far easier to tune a high quality set of speakers with appropriate electronics, than it is to find a speaker that matches your electronics and gives you long term satisfaction.
But obviously that opinion is just the result of my experience. YMMV.
