I have mounted BuffaloIII-SE with two entries:
SPDIF Hiface
I2S Amanero.
At begin the two inputs are equal, but after several days of use, I2S signal now comes with an attenuation of 8 dB over the same SPDIF signal
Just is the same in I2S Amanero and I2S Luckit.

8db is a strange number... That does not make any sense.
Pictures might help us spot a problem, or it could be something at the source.

Thank you for your answer.
Located the problem. The failure occurred by the clock power suply. I not exactly know how this -8 dB attenuation occurs. It is when the value deviates 3.3 v. to 3.28 v. It seems that with these 3.28 v. the problem was produced.
I have reviewed the solders and now is OK 0 dB. I will see if the value deviates again 3.3 v. to 3.28 v. after many days ON or was a bad contact only.

Hmm, I think you likely have found the problem, but I doubt it was actually the .02V difference itself that cause it. That sounds coincidental. Likely it was just a cold joint some place.

It´s something strange.
Without touching anything happened after two days continuously ON. And the only place I've reviewed solders is on that power suply.
I've reproduced putting a different source adjusted to 3.28 v.
It also might be doing something wrong. 8 <((.
Thank you very much for your attention.

That sounds very much like a power sequence issue.
