A friend of me use since any months for his no longer available Kaisaya power amp units (Accuphase E505 clone) - go to

a power transformer from this series:
https://sklep.toroidy.pl/en_US/c/To...EME-AUDIO-GRADE-V2/99/2/default/1/f_ov_8_78/1
this version:

No mechanical hum and very good sonic performance are recorded.

This brands are also known for good quality, but more expensive:

1) Tauscher (Germany)

2) Plitron (Canada, now Noratel)

Could it be that these brands have a number of further advantages (like e.g. an integrated snubber network) that one don't find at Toroidy?
Thanks for any information.
