I believe it only puts out 15wpc so you will need a fairly efficient speaker. I would also avoid anything with a metal dome tweeter. If you're planning on using the tuner section make sure it is working before you buy. I used B&W DM100's which were bookshelf speakers I bought in the Mid to late 1980's. If I were shopping today, I would check out Cambridge Soundworks as I would think their speakers would be voiced to work with the Advent. That said, I replaced my Advent receiver with an NAD 701 receiver around 9 yrs ago, which thoroughly outperformed it in every parameter. My Advent sits in my attic where it occaisionaly drives Radio Shack Minimis 7 speakers (remember those?) for background music, when I am working up there.
