HUB for this, FF for K11R2R and FN for NU-DDC.
Originally, all three of the above were using the BRi-PSM01-F from Burichan for analogue power supply.
Even in that state, I had no complaints at all because the dynamic range was several steps wider and not harsh than before I put in the BRi-PSM01-F, but both highs and lows had better extension.

But when I heard that a new model had been released, I couldn't stand still and asked for help.

The results are fantastic! That's one word for it... but it may not be enough to tell you what it's all about.

Firstly, in my personal experience up to now, when a high performance noise filter is used, the noise does indeed seem to disappear, but the sound tends to lose its liveliness and become either muffled or, on the contrary, edgy and harsh.
I do not feel those negatives at all.
There is a part of me that uses electrostatic headphones so that I don't feel those negatives, but with these, even dynamic headphones have no problem, on the contrary, the dynamic range is further expanded and the sound field is naturally expanded with a good sound separation, especially in the bass. The sound image is also very easy to recognise, and I can no longer go back to the original environment.

In truth, it would have been best to replace the power supply, but it was very easy to install as we already had a lot of analogue power supplies to switch from switching power supplies. Thank you very much.

The F2N, which was purchased in October, was included in the comparison.

<without noise filter>.
I have become accustomed to my F2N ears, so when I listen to them plain after a long time, there is a lot of clutter and I feel like I am listening to some kind of slow playback.
I would have had no complaints before, but I have become a luxurious ear.

<Petit Susie + Petit Tank>
The clutter has been removed and the music is now easy to listen to at once. It's not slow, but it doesn't sound fast and gentle.

<BRi-PSM01-F2N>
Transients are improved at once, each instrument is expressed realistically and a thrilling feeling is generated.
The clutter has been further removed and the sense of volume has increased, making it enjoyable to listen to music in a simple way.

<BRi-PSM02-FNC>
I liked the F2N so much that I asked to have it made with the desire to hear a better sound.
The volume is a little gentler than that of the F2N, which has been aged more vigorously.
Is a more mature sound the aim? I think the reason I don't feel inadequate is because the transient performance and the amount of information have increased further.
In orchestras, the resolution of wind and percussion instruments in the back rows has improved, and the expression of violins in the front rows has changed so that you can see the player's playing movements.

Round 2, Eva Cassidy True Colors (acoustic) to listen to
https://www.youtube.com/watch?v=Rka5vDLdHfA

<without noise filter>.
This blurriness somehow reminded me of VHS picture quality.

<Petit Susie + Petit Tank>
Improved DVD quality and much less sharpness of Eva's breath.

<BRi-PSM01-F2N>
As in the first round of listening, Eva's voice and guitar are at once more vivid here.

<BRi-PSM02-FNC>
I noticed that the intro guitar solo section also included a neck-squeaking sliding sound.
Eva's voice lost even more of its sharpness and became smoother, while the guitar lost its sweetness and became more taut.
The clarity of Eva's voice took over in the chorus section, and the guitar didn't just sound like a guitar.
The guitar has changed to a realistic expression that reminds us that the guitar sound is produced because the strings are being plucked.

In general, the detail information has increased significantly from the F2N, and I've been wanting to re-listen to various tracks as they age.
