There are some used Mackie's selling on Ebay. You want the Mackie HR824.
Just a suggestion, but I like those speakers. They are rated to be flat down to 40 Hz and I believe it. Amazing high and low extension for a bookshelf monitor. Great sounding. Must be something to do with being bi-amped, with a more powerful amp for the bass. They can be used with or without a Sub-woofer. I don't know a lot about two channel pre-amps, but there are quite a few used ones selling on A'Gon.
