Acquiring an awesome system, but how?

At this point I am making some changes to my system that may raise eyebrows as have in the past. But it's my money and my ears so here goes.
If one was to count all the makers of high end stuff and multiply by how many pieces will be included to create a system one would get the statistics of possibilities of combinations. I bet it's as high as our deficit, did I have to bring that up?
Well it mind as well be infinite because no one can even approach a fraction of all the possibilities.
I still haven't picked up an atma-sphere mp-1 preamp, so every now and then I look at the forum and see some suggestions for preamps to see if something comes up with raving reviews.
Well most of us know it's mostly synergy that makes a system excellent.
I thought the experienced goners can shed some light and offer suggestions as to what will make lasting purchases.
On my end I was amazed at how good the atma-sphere m60 sounded while it was running, now it is on hold till some things get resolved and so now I am back to the sim w-5 and it still satisfies. But I would like to do some more comparative listening, because the atmas sounded so good. I have no intentions of letting go of the atma's by the way.
I am still after the mbl sound and will be experimenting with some non-mainstream designs. I have some good ideas that will take time to bring to fruition.
But as for the reason for the thread, please share with us what systems made the biggest impressions and how one achieved them without breaking the bank?
Please include what systems sounded the best to you.
