I replaced two MKP Arcotronics with Russian PIO K40y9 0,033uF as coupling caps in my Trends TA10.1 amplifier.
The main goal being to create a 96Hz high-pass filter (see my other post).
But man! The PIO caps are not even burned-in at all, and I understand how dull, lifeless and boring the original Arcotronics MKP were!
These PIO k40 have so much energy in the midrange, it digs up details and brings so much life and light without sounding harsh or unnatural, it's FABULOUS and they cost me a couple euros each! It sounds just SOOOO good! I'm a happy camper!!! :)
I'll see how it transforms after some burn-in time, but I'm already fantasizing of replacing all coupling caps in my system with K40y9. (But maybe it would be too much of a good thing).
Anyways, STRONGLY recommended.
