Hi Sakis,
It was made intentionally so it must have some purpose. The Japanese never did something for no reason, they must have research and found some anti-resonating properties or something. Maybe the owners manual or marketing brochure will have reference to some unique feature of the amp.

hello Nico ...always nice to hear from a friend ....
beyond capacitors best regards for you and family and i wish things a re better in SA than is for us in Europe
( still though we actually do fine )
as about the manual or a service manual i can only locate the SE 900 which is different from the SE 900 SM 2 and doesn't have this feature or any reference on the specific cap.
somewhere far away in the past i recall that i have seen the zobel coil ( inductor) rounded on the capacitor but this one is no part of the circuit
kind regards

Hi Sakis,
Technics TA-KE II caps. Babboo fiber in separator and that spring should probably give both stiffness and damping to the cap body due to dissimilar metals. Not to mention a fancy spiral look through the heat shrink wrap.
I think this is mostly snake oil but at least it does make the amp itself worse.
I have myself recently restored a SE-A900 SM2 and IMO it sounds very good.
One thing to watch out for if replacing these caps on this is the cap support pins. On the PCB one support solder pad is not insulated. Usually cap mfg specifies that support pins should be isolated (NC). Easy fix to isolate pin/pad on the PCB.

Hmmm,.. resonant electrolytics, eh?
