I wanted to purchase this “tweak” accessory for my Naim 252 / Supercap / NDS / 555PSDR / 300 system.
It is a product of the Japanese Furutek of which I do not esteem being a serious company in my opinion.
It still has a few hours of use.
The product is inserted in a free plug in the same power strip where the other electronics are connected or before the mains air conditioner / regenerator.
It’s incredible but the insertion or not of the device changes the sound and is immediately true.
The product makes the sound more defined, really “clearer” as if it were “drawn” with more clarity and a veil of noise had been removed around it.
It is as if there were more treble even if it makes the mids less mid-range I don’t know how to explain it, as if there were more clarity, an effect similar to the “clear voice” function in televisions.
This effect may still be temporary because the product has just arrived at my house and I am testing it.
But absolutely the device changes the sound, it is crazy that by simply acting from the outside of the electronics at the current level, inserting this passive element changes the characteristics of the sound.
But I don’t know if I like this “clear voice” effect more or not.
For this reason, now I have it burned in for a couple of days, then I test it definitively.
Does anyone have any experiences with using this product or with the break-in times?
