I have been burning in my Magico S5s now for 2 1/2 weeks, and happened to insert Stillpoint minis under the MacBook Pro, and Ultra SS (4) under the Spectral 15SS preamp. (I ordered from Music Direct, as they will give a 30 money back if not happy) I was not prepared for the change that took place. Really, if you haven't tried these things, you owe it to yourself to give them a try. Soundstage is deeper, wider, more precise, detail is much improved, background is more black. Cymbals have more shimmer, detail is improved but still natural, bass notes are more distinct. They are the Audiophile's version of crack. Looks like a few more orders will be coming down the pike. No wonder they offer a money back deal if not happy.
