The sound equipment reinstalled was: A SAC / CD player, a 300B valve audio pre-amplifier, a L34 valve amplifier and speakers. No turntable.
The following comments have been translated literally:-
“I have noted a distinct improvement...the truth is that I hadn’t expected such an obvious and remarkable change.”
My first impression was one of a general clarity to the music. The second was that the stereo performance was much more precise. In addition, I noticed a great change in the high notes.
One thing that particularly caught my attention was the improvement in the music through headphones, which I use a lot. For me, this was a real bonus and something that I hadn’t expected; I had only expected improvements in sound from the speakers.”

Technical response from Artesanía-audio
The explanation of this surprising result is that once electronic equipment is in use, it produces vibrations in different frequencies that interact and inter-modulate. This effect is responsible for the lack of neutrality and linearity in sound reproduction. (This can be proven with an accelerometer with different sensors.)
The treatments used on the products in the Artesanía-audio range afford them isolating and shock-absorbing techniques that raise the absorption co-efficient to the optimum level. Surpassing this level can actually result in poorer sound quality that affects the dynamic passband.
