Capacitor pricing

Here's something for all to ponder over. 
Just for my own interest and those here who are interested, I viewed all the dimention specs of one of the expensive "boutique" favourites against the same from Solen, both in "metallized polypropylene capacitor 400v" versions.

And in every instance for 20 different value the same uF 
1:The cap body length = exactly the same!
2:The lead lengths = exactly the same!
3:The body diameter was always 1mm more on the "boutique" "maybe re-badged" favourite, what would cause this?
I'll leave that to everyone's imagination.

The upper level Solen are solidly good capacitors however there are better. My amplifier uses Solens as first stage coupling capacitors and I replaced them with Jupiter copper foils for a noticeable improvement (not night and day).

My speakers have Duelund CAST copper foil caps that replaced the Solen at the tweeter, a "very " noticeable improvement. Money well spent IMO. To be clear, the sound was quite good with the stock Solen but superior capacitors will make a positive contribution.

To all I was just making an observations and assumed  everything was within 
a percent or two  to see a $40 difference per capacitor is lot . Parts connecxion 
runs 20% sales on capacitors off and on ,as well as other things . Just compare 
between all like Madasound , Sonicraft, Michael Percy audio and other 
lie Hifi collective in the U.K  sometimes less money and reasonable shipping
one pet peave if you list it ,it should show how many in stock. Such as a Hifi collective does.

George, don't leave us hanging. What are the brands you think are the same?

One of the "tells" for me is the 7.5uF caps, which AFAIK only Solen/SCR makes.

George, don't leave us hanging. What are the brands you think are the same?

I won't outright name a product of rebadging, but if you spend the time and do your homework you will see for yourself. They have selected 20 from 1uF to 100uF from that Solen series and voltage, and if you compare dimensions specs cap for cap you will see, that all "boutique" are not what they appear to be.
