I agree with jerryg123. If you get 1 very good component and the rest are low fi, the system will only sound as good as the weakest component. I'm not saying that you have to spend $10k on every component, but if you get 1 very nice component, you should try to match that level of performance with every other component.
As for price, you are not going to get top quality sound from a $500 tt or a $700 dac. $7k for a dac, $10k for a tt/cart/tonearm, now you are getting into good sounding gear.
