Okay, I'll bite.
I really like the System Audio speakers that I've heard, and I think they offer really good performance for the money. The sound tends towards "fast" and "open", but with better bass than expected from the cabinet and driver size. They image extremely well also (probably those slim cabinets again). On the downside they can tend slightly towards leanness and should be partnered accordingly, but when you get it right they are excellent. I would also say they are probably more suited to the size of European rooms as opposed to US caverns (of which I am insanely jealous!)
The 1750 is a great speaker, although I preferred the now discontinued 1280 at the same price. The Explorers (from the few times I've heard them) sound excellent: they're detailed and open, and can really rock. They make a killer combo with a Krell KAV400xi.
