I have to agree, the SL1200 is a great place to start for a music rig. At your budget you should consider powered speakers. The Equator Audio (
http://www.equatoraudio.com) D5 ($300 pr.) or Q8 ($1000 pr.) offer a stunning level of performance for the money. Built as studio monitors, they will play louder and cleaner than any other equivalently priced amp/speaker combination. More importantly, they are voiced to be phase coherent and tonally neutral. Phase coherent speakers are a vital ingredient to unlocking the magical qualities of vinyl playback. Plug your preamp into the speakers and you're good to go. Even if you upgrade to a bigger hi-fi rig in the future, good powered speakers will always find a home next to your computer or in a secondary system.
