I have run the Super 5 Monitors for close to two years, sometimes with the Deep Hemp sub, and sometimes without. My two favourite amps to run with these speakers are the Decware SE84 basic and Select, and the 20w/ch Ideal Innovations Elite 80 push pull. With the 2 w/ch Decwares I prefer to run the sub, though without it the sound is still full. With the Elite 80, the sub is not needed in that the bass is such that when a friend was listening to them, repeatedly asked if the sub was on. Comparing the sound of the Super 5s with the Decware or Ideal, the Decware has that smooth, etherial, warm sound that good SETs are famous for, and the Ideal is slightly cooler, drier, but punchier in the bottom end. Both are lightning fast and both have utterly incredible soundstages with layers of detail. With these two amps the Super 5s are the reference I use for all other gear, and to this day the only speaker that can get near the Super 5s are other Omegas.
As far as the desktop goes, the Super 3i with the basic Decware SE84 is my reference. If your computer is your work, have fun getting any done if you have this combo playing.
