Capacitor

Ugh. I’ve seen this on several other threads —people attacking capacitor upgrades in a high handed manner. 
I purchased a certain budget preamp that allows capacitor rolling with built in binding posts for caps on both output coupling and gain stages. It is $1k new abs I got it for about $600 used.  You can swap caps in a moment (once you discharge them safely). I bought this thing because it was easier than building something like it. 
I don’t need Raul to tell me anything. I’ve heard the sonic differences in caps.  Wima  are fine caps that do a decent job and meet spec. But they do not come close to things like VCap.  
Yes they are pricey things. A pair of great caps can set you back several hundred bucks. But the sonic differences are easily audible —more so TO MY EARS than a power cable, for example.  
While it’s true that some manufacturers just  use Wima or other decent caps, it’s also true that many do not. 
It’s also true to my ears that a decent 6 or 12 volt reissue preamp tube can sound great and quiet. So many get a bad rap yet manufacturers use them all the time. And it’s also true that some NOS tubes can sound magical and just better. It’s not practical to source them when building to a price point.   
Thanks to Granny and Charles for keeping decorum and encouraging folks to listen for themselves. 

@jbhiller,
The lack of even a modicum of self awareness to recognize the level of patronizing behavior on display  is stunning.

I'm generally skeptical when anyone claims objective superiority for any particular piece of audio equipment or part. So, Raul claims Wima is the most superior cap for any use. And now it appears claims Odam is most superior cap for any use. While I remain skeptical to this claim, I'm willing to be open minded.
So, why would the Odam be the go to cap for every situation? Some claim it sounds like no capacitor, perhaps that's a good thing, perhaps not. If it has no sound may expose other parts in circuit, may not be a good thing. I want my caps to have a sound signature, obtaining pleasing sound signature requires recipe of different flavorings. As far as other parameters of sound quality, such as transparency, resolution, more should be better.
Hard for me to believe odam has no sound signature, never heard a single parts replacement or wire/cable that didn't have some sound signature. And if it has a sound signature may not be best cap for all situations. Perhaps natural would be descriptor I could better understand, even with all the baggage that term invokes.
