Does your "Phono pre-amp" have volume control? If so, you could buy a pair of powered monitors and be set. I use the Quad 12L Active monitors and think they are very good. They are a very attractive mid-sized monitor which have built-in bi-amp 60 and 40 watt amps in each speaker. You simply connect them to a pre-amp with a pair of RCA or balanced interconnects and you have a complete system.
I also own a Nuforce Icon amp, but not the matching speakers. The Icon/S1 is very cool, but I think it is designed mostly as a very near field desktop system, meaning the speakers are within about 2-3 feet of your listening position (John, please correct me if I am wrong). If you are trying to fill an entire office with sound, not just your desktop area, I think the powered Quad monitors are an excellent choice around which you can build a very good sounding system.
Enjoy,
