I am continue to look into Avicenna and trying to resolve a puzzle why when Avicenna is engaged the sound compare to the sound of the “Wall” looses dynamics. I do not compare Avicenna with PP2000 but rather I compare it with the sound of the Wall. Avicenna objectively outputs a perfect signal and there is absolutely nothing in the electricity path that might be responsible for sonic degradation. The whole idea in Avicenna is that electricity goes directly from input to output with no passing there anything but just “spruced” or complimented with by Avicenna’s processing. If the Avicenna’s out is objectively perfect wave then why Avicenna’s sound sank?

We have a disagreement with Dima about it. He feels that the key is in the specific distortions that need to be deliberately injected into power line in order to make the sound “better”. Avicenna has built-in special injection functionality and Dima pushes me to start using it. I disagree and refuse to use it so far. The injection functionality is fine and I will be there bit I think about injection as a cream on the top of the probably baked cake. If cake is faulty then no amount or quality of cream can be benefited in the way how it might be if the cake were good.

I certainly do not claim that Avicenna is faulty; in fact it performs absolutely perfect and dose what it need to do. However, there is something in what I do that impact sound negatively. It can’t be otherwise as Avicenna outputs absolutely perfect electricity with no distortions. It is can not be that “perfect electricity” would sound less dynamic then clipped and high distortion electricity. Something is wrong and I think that the experiment with injection might be started ONLY what the sound via Avicenna would be not worse then would from the Wall. Otherwise if does not make sense to me.

Take a look at the images. This is CD transport, DAC and preamp (65W and Power factor 0.7) driven in top image from the Avicenna in bypass mode (effectively right from the Wall) and then the Avicenna power processing is engaged. The images contain both voltage and current sinusoid and it is absolutely obvious that with Avicenna the voltage and current wave are way more able. Why they sound worse?

BTW, do be distracted with current sinusoid – this is how the crappy power supplies with capacitive input work. You might compare with the imaghe below that shows the way how Melquiades (that uses only input chokes) sucks current.
