Well, it's hard for me to say how much better it is, I personally prefer it because of the better lower part of the audio spectrum, it has a lot more kick in the bass than Le Monstre and as far as details and highs are concerned, I think they are equal, although some of my friends say that Le Monstre has more details though.
However, it's all a matter of taste, but the fact is that this amplifier(with regulators) is in the range of small amplifiers in A class such as JLH69, Le Monstre,...

Count on some 3 - 4V voltage drop, which would roughly be 6-8W dissipation per regulator with 2A of current, for four regulators or stereo amplifier 36W max.
First this weekend I have to make a version with Dale tantalum resistors, then I will start drawing the schematic of the regulator 😉.
Yes, this morning, but because of Sunday's family lunch, I didn't listen until tonight. I must admit that I am delighted, you can really hear the difference between the MMA0204 and the PTN SMD resistor. Even my wife feels the difference in the sound, which is no small thing🙂.
I built from Plantefeve the Zenotron / ProFet (similar to F5) and Zenquito. The second one I never tested.
Interesting and nice build!

I have also made a couple of amplifiers from JM Plantefeve, but this is the best for me so far, especially when I made these upgrades with regulators and parts.

So which ones are better, the Thin Film MELF Resistors, or the PTN Thin Film SMD Resistors?
I expected that answer but I wanted to be sure. Thanks!
Great work by the way. And kudos for sharing the results with us.
Do you sleep (much)..??

Compared to the Vishay Dale RN series are also these PTN smd resistors better? If so then what would be the main difference in sound?
Waiting for regulators schematics. 😊
PTN are better then RN , I tested in my regulators for AD811 , PNM are even better.
I would like to try this amplifier. I have ECW20N20 and 20P20. Can I use it in this amplifier?
is it posibble share your regulator? We can apply it the same way. Maybe we can print pcb together for those who want to apply it..
thanks.

20N20 and 20P20 will be more suitable for the version from post #56 or the classic version with a slightly higher voltage. The IF170A that I use has a lower Vds than the 2SK170A so in that case with a higher voltage the 2SK170A would be a better choice.
The regulator I'm using has copyrighted parts, so I promised @viltsone that I'd post a simpler schematic very soon.
