What is most important part of a system?


I remember reading someone saying that the most important part of a system was the source. I thought "Wrong! Speakers are the most important".
 
Now, I have changed my mind. Source is the most important part.

Right or wrong but this is how I came to this conclusion;

I have tried the same system with a CD player and a turntable. By far LP sounds better than a CD. Btw, the system had all high-end amps, speakers, cables, etc.

What is most important part of a system for you?

Well, bigkidz,
Sounds pretty dam logical isn't that?
If there's a $35k budget for DAC, why not try $250 DAC and see what changes positive or negative rite?
great question , but its all important garbage in garbage out so a good front end is important, the right speakers are also just as important they all sound different in my room anyway , room acoustics very important or your never get the best out of any component, a better quality sounding amplifier can make a huge difference to sound quality ie going from a good ss to a great valve or vacuum tube amp is an incredible experience ,also trying a passive pre amp can be incredible also but im going with the front end as the man behind linn said garbage in garbage out , another wise man once said you cant polish s**t
all true, but the real issue is where to spend the most money

that is the way this question is usually interpreted anyway

with digital, that means the only transducer left is the speaker (and as per above, its interface to the room)
