Poll: Most impactful component

It was the Preamp for me. I had a solid system and when I upgraded preamps it was staggering. I had spent about 10k on speakers and 10k on a turntable and truthfully only had midfi amplification so I had to choose. I flipped a coin and upgraded the preamp and was blown away. 

Oh I forgot room treatment.  I bought approx 100 Auralex tiles and 24 bass traps. Honestly this did more than any component.  Actually it did more than all of my components.  I know there is still some room correction to gain and I only spent about 1500 but it made a GIANT difference in my room

This is great thread!  My answer--I have no idea.  

How great is Roxy's metaphorical assessment of the system? 

Speakers = Body & Voice

Amplifier = Heart

Pre = Soul

I would add that Source = Blood 

For years I fought the notion that the preamp was super important.  Then I got a legitimate phono preamp (Manley Chinook--still own it despite lots of swapping around).  That made me realize that if a phono preamp could make that big of a difference, how about the preamp itself?   That was eye opening. 

Maybe I should be asking myself, What component is the one to skimp on, if you had to? 

My ears are only 51 years old but I can only hear to 13k. My 35yo wife can’t stand the super tweeters I added to our 2 way Altec horn system because she can hear 19k. I have a toggle switch that takes the tweeters out of the system when she listens with me. It’s sucks to have tweeters that you can’t hear. They do seem to add air though. Now I wear earplugs while mowing and riding my Harley to preserve what I have….
