suggestion for a multi channel pre/amp please


I am looking for amp / preamp suggestions that can run multi-channels; I have existing 6 wall speakers that I need to run with my cd player. I am not too knowledgable with these things so I apologize for any silly questions. Do I need a multi channel amp and pre? do I need both, or which one can I purchase first? My budget is is the low-mid $2k range used or new. Thanks for your help.

try a new rotel unit..i purchased one for a guest room HT set up as it has all thx, etc applications .. as things turned out, the room wasn't ready so i put in in my main system's room which is also our dining room. it has been used in 2 channel mode exclusively and i am stunned at how complete the unit is..no coloration, etc. i did buy a power cord from Signal for about $65 and it helped tighten up things. sorbothane feet, also..i listened to everthing in the $ 1500 range and neither the denon, nad, or sony beats this player. plus, it is very easy to use. after breaking in it sounded even better....i think the 70wpc integrated is about 1350-1500..test one. and put the balance in yor bank or towards music. ideally, you could find a demo model, broken in and at a significant savings...
Thanks for your feedbacks. Please keep them comming if possible ( the more ideas the better ).
A used Integra preamp would be good. The one that goes for a lot of money; not sure of model number. NOT a receiver.

Used Tag McLaren is less than 2k and very good but the future of the company may only lie in car chassis for formula one and not in high end audio. Never know.
