The overall advantage with the Klark TekniK item or similar ones is that we have de control of that " tailored " kind of quality performance and we are not at out of control an at random like with the boutique combination caps.

In that regards there is nothing that can does the caps for we can have the control we are in the caps " hands ". Now,  our items in the audio systems  already came with caps ( that makes it's technical job. ) and  the eq. path is for fine tunning that audio room/system: advantages are to many to name it here but just " think about ".

I have been doing capacitor upgrades for some time now i,especially coupling capacitors in dacs, preamplifiers 
and loudspeakers . The best capacitor for detail  is without question the VH audio CUTF  -Copper foil Teflon it only goes up to 
2 uf I believe , as a main Cap ,my best combination is
for main cap Jupiter Waxed paper Copper foil ,which inside a amp is good to at least 160+ degrees ,no more bees wax. Use  up to 3% of the VH audio CUTF bypass capacitors , they are pretty expensive and room in m any cases is an issue ,I just installed this in my Coda CSIB integrated , and helped a friend in his Loudspeaker this is better then the Duelund cast  capacitors 
at much lower cost they do need a solid 400 hours to fully open up 
But a fantastic combination ,and my preamplifier now is in another league sounding . If you email me I can send you a couple pics to show scale,size.

What I forgot to mention the Duelund are a great capacitors way too  much $$
and huge, they  are top notch caps great detail and depth ,just slightly better the the Jupiter in layering ,but the Jupiter Copper foil has great overall balance, and much less $$ ,they are within a % point or two of each other 
detail on top is very good on both  ,but the VH Audio CUTF  is the best of the best in that 
dept by adding between 2-3% in the VH as a bypass cap the best of both worlds
if you have  a capacitor you need 2 uf or under the VH audio are pretty neutral 
slightly to the warm side but very big and for a pr of 1 uf for example around $1k.
greatness  cost $$.

Jupiters will be here with me in 2 days can some one explain how many hours of burn in will open the cap and what should I expect in the sound  in the process of burn in to stay on track and not discard the caps
