The same dilemma exists with buying both old, new and recent gear which is - will you like the sound? To be truly satisfied with your purchases (unless you get lucky) it will be necessary to audition the components first. Much of the quality sound that any system achieves comes from the synergy between the components and between the components (mostly but not restricted to the speakers only) and the room. Another consideration is if an older component can still be repaired, if needed, (are the parts still available?), some odd ball resistors and such are not. In your price range I, personally, would consider a relatively new/used integrated amp (an easy/out I know). I own a Musical Fidelity (now discontinued) X-A1 amplifier that I purchased new, on close out, for $500.00. It sounds as good (to me) as much more expensive SS gear that is in current production. To find out if you agreed with my assessment of the amp would, once again, require an audition. When in the past I have been unable (or too lazy) to audition equipment, I at have at the least discussed the component with people that have used it in a like or same system (I recently did this with power cords and got lucky:-). This is also a great thing about the Net and these types of chat rooms, which make this information available to those who don't mind typing a little bit as well as reaching out to complete strangers for feedback and info, which you are already doing and which you might even want to take it a little further with the names and models of the gear that you are considering for your system. If you don't get many replies, don't feel bad as I doubt if the combined masses here have had experience with every component ever manufactured, but we might also be quite surprised at the number of pieces that have gone through this mass of hands.
