Hi Mark
I must report this new experience.
This morning I was working on the Essence of my "little cMP2", a portable unit that I've build to allow my friends to listen a cMP2 in their systems.
It was intriguin also for the PSU challenge, using the discrete Switching unit of Silverstone SUGO SG 5 coupled to a picoPSU (150 XT) through a run of Silmic (4000 mF) (also feeding the 12V of Xonar). Another run of Silmic was in the 5V line to the Xonar and 2000mF was put on the P4 line.
The "Sughetto" was build around an Intel 13 530 CPU (COOLER THERMALTAKE Ventirad Slim X3), a Gigabyte H55NUSB3 miniITX , a SSN Corsair for OS and one RAM Kingston 1GB 1333MHz DDR3 Non-ECC CL9 DIMM. It works well, it's a good Ambassador for cMP2 and, sincerely, it sounds really great-
On the table, this morning I've found the P24 extension with ferrites, the Sugo case was open and so, I put it on the P 24.
FANTASTIC RESULT!!!!
More air, more harmonic richesse, more silence in the background.
At this point I've added another ferrite on the P4 cable. Even better.
Now I must suppose that:
- This is a different mobo, with very different regulators
- In every line where I've put ferrites it exists a run of capacitors
- The phenomenon I've observed yesterday in the other my system is not due by picoPSU or Soundboard, in this case closer to ferrites then in other system
Here you are my nude "Sughetto"
The Essence side
The Ferrites and capacitors side
PS: here there are fans inside: impossible to avoid them.
Follow Ups:
After few hours of listening I've tried to remove extension and ferrites of P24.
It's better without, for me.
A lot more dynamic and slightly more transparent.
I'm perplexed. the effect is not surely the same I've noted in my principal( and linear) PC but without ferrites is better for me also in this one, period.

Hey Danielle when I put ferrites on p4, p24 I got a darker sound (more like less bright) but more transparent to real upper mid musical cues. I heard more real info, got a deeper bigger soundstage.. I also got a bit more dynamics. Both Mark and I run 44 sr not 192 sr like I believe you use. That may be part of the reason for different perceptions. If you like your tonal balance before ferrites you may not like it with ferrites. My only perplexing reaction is that I don't get the huge sq pop that Mark gets at least not with my current mobo. Even though I dont get the big sq improvement I still prefer my system with ferites than without them.

Hi theob
it's possible that upsampling I always use ( 24/192) reacts in this strange way to ferrites but It's the first time that I apply a reccomended upgrade with negative results, so this it seems strange to me, especially 'cause I can't find a valid explanation. I've found some positive effect putting ferrite on the line coming from linear PSU, bad one on the line "after" the picoPSU (the extension cable).
I must underline that my Sandy Bridge setting adds both dynamic and transparency to SQ so, maybe, ferrites action could be useless with this setting, also for the very different local regulators quality in the new mobo.
Anyway my "ferrite's story" stops here, but I'm curious about further developement, so I'll wait next Mark's report.
Thx to all
Daniele
