VICTORY!!!!!!!!!!!!!!!!!!!!!!!!
The fully-cut NPA SOUND HOLE makes the Toroni Nr.1 guitar sound like perfection!!! (raw sample recording to come very soon)
--------------------------------------
Why was I convinced to make the NPA sound hole "semi"-cut the first time?
Well it was because my successful experiment, the Eytymiades handmade guitar was cut that way and I didn't feel like changing something that worked. Thus I actually thought it worked because such small obstruction of the hole might be negligible, and I just didn't want my luthier παναγιωτης Λαμπης to be bothered with extra detailed work and hassle.
But now that I KNOW that the hole MUST NOT (!) be obstructed, I wondered: why did the Eythymiades guitar sound soooo good?
I believe the answer is to be found in the 7th photo. One can easily notice that the guitar thickness (distance from top to back) is smaller at the upper portion of the guitar. This could explain the slight tendency to the "brighter" side, and this extra "brightness" was luckily compensated with the hole obstruction it seems. (Also compare with the 5th photo of the Toroni Nr.1 guitar)
In any case, there is typically one more experiment to be done and that is with the Dieter Mueller handmade guitar. I will again do it in two steps:
1st a semi-cut NPA Hole (just like with the Eythymiades guitar and Toroni Nr. 1 the first time) and (if needed) THEN a fully-cut one.
(Because, let's be honest, there are many factors that contribute to the tone: woods, glues, top inner manufacturing techniques, you name it. So if I can have at least one safety step, why not use it? )

Here are some photos of the Toroni Nr.1 guitar sporting the NEW NPA Sound Hole
---------------------------------
(small issue)
I need to run some tests before uploading an audio sample because there is still a tiny bit of "darkness" with the guitar (playing with the proper strings that Guitar Tone Grading suggested).
Right now 2 scenarios come to mind:
1) (since I decided not to cut the fretboard) -> the fretboard and little pieces of wood left and right cover the hole a bit giving a "darker" tone (--- highly doubt it, I would consider it negligible)
2) the new hole affects my Guitar Tone Grading system (GTG) by a grade (or two?) (--- I believe this might be the case)
Maybe the ordinary hole which offered a "darker world" matched with strings that were proportionally "darker". That might have tricked my ears and I can see it makes sense!
(even though the opposite could also be expected, for me to have used "brighter" strings to compensate for the "darkness")
So an update will come soon, plus I have one more guitar left to test and confirm the findings I get from this guitar

Kudos again to παναγιωτης Λαμπης for being a highly-skilled luthier!
