Hi, i tried to PM you but since im new member, i couldn't and asked about it from a mod:
"It's temporary while you're a new poster. However all you need to do is alert someone like this @matsurus and ask them to PM you."
Can you PM me? I can also use your www.inserra.it email adress if you want...

Sorry Dario it’s not a Clarity, it is an Auricap xo 200 vdc, going to order one of the clarity but I thought you were going to say Audyn or murdorf. Thanks

While I consider the CSA slightly better than the XO (the CSA is less neutral while the XO is slightly dryier) it's not necessary to buy it since you have the XO, they're more or less at the same level.
Proceed with the one you have, just in case you will feel that the amp sounds a bit dry you can upgrade later, perhaps directly to the CMR which is FANTASTIC with the FE.
I would invert transformers and PCBs so to avoid signal cables passing through transformers' magnetic field... see on the build guide (here you will also find order codes for HIFI2000 cases that will fit, including the dissipante variant).
Thanks Dario, yes transformer go to the front, I was so excited didn’t notice I was setting the wrong way.
Dario , have a question, do I need a soft starter , if yes do I have to install an On / Off switch planning to leave it on all the time. Thanks again for this wonderful project.
Happy New Year to everyone participating in that group buy and also to Mr. ClaveFremen. I was able to finish the project just before the end of 2022. Here are some pictures. Hope you are also satisfied with the result. Here are some photos. Have a good and successful year.

Nice build! 🙂
Let us know how it sounds, I'm a bit worried about your choice for C1, C2 there should be Nichicon PWs there.

Well, first of all, I made a mistake when I was posting a reply, I wanted to write that I hope you are also satisfied with your results as well. I have built My REF A and My REF C as well in the past. My REF A was the first serious amplifier I made, so maybe that was the reason I was always somehow attached to the Mauro Penasa topology. My REF C was my daily amplifier for the last 3-4 years. Probably it is too soon to speak about the sound of the Fremen edition. It has not been running for more than 20 hrs. But for now, I can tell that this one is more transparent, something like there is more air in it with also more detail. When I was listening to it yesterday, I was enjoying it a lot, I even did not want to go to bed 😀 To sum it up, it is good, it is very good 🙂
Hi Dario,
Is there any board left or I have to wait for another batch?
EDIT: Just found the information form page4. Unfortunately, I can not PM you due to the new member policy. Perhaps you can start the conversation for me?
Thanks!

Hi Dario, after having read almost the entire forum My "audiophile" approach to the LM3886 and having greatly appreciated both Mauro Penasa's work and yours, I would like to tackle the construction of this amplifier, could you tell me what I need to do to purchase the PCBs and possibly the components?
I finally managed to complete the myref Fe, after a long wait the lm3886s arrived, what can I say fantastic sound, a nice leap forward compared to Mauro Penasa's myref, detail, depth of the sound stage, deep and articulated bass, congratulations to Dario for the work you did, thank you!!!

Ciao Dario,
Im Gabriele from Emilia. I'm interested in 4x single PCB of your last revision.
Do you have them or I must wait the new GB? When?
Have you ever wonder to put a socket dip for OP AMP or since the compensation would involve other changes is a bit useless?
Thanks and have a nice day!
Ciao Gabriele,
since I'm moving and it's not practical for me to organize a GB in this moment I've ordered an extra batch of boards, same conditions as last GB but, since it's a small batch, price will be sligthly higher at 30€/PCB kit (2 boards).
PM me if interested.
Originally the opamp was not supposed to be swapped and an SMD design made more sense for performance and layout reason.
Now that alternates are a possibility still does not make sense since they are almost all SMD only and compensation must be changed a bit according the chosen one.
