Some dealers already do this sort of thing- have pre-configured system options at a price point, and you can swap stuff in and out. Audio Systems here in Austin offers that. Obviously you'll want to listen and see if it works for you. Pretty hard to beat having a good relationship with a reputable local dealer. I am not affiliated with Audio Systems in any way.
Would you trust a local dealer to help you put
together a modest system. (think $10k). Let's say you got tired of the whole "system building on my own thing." If you had a good local dealer, would you go take a chance on them and say "I want speakers, an amp and preamp (or integrated) that will sound good in a small to medium size family room." "I already have my sources." What's your take on this?
