Received my order today, and played with it a little.
As I suspected, it gives some and takes some, on expensive cables and gear is not something to use, on lesser gear could result.
It is an interesting device but not for me, but now I have 3 of them to play around on other devices from my network. Is a good product.
On very expensive cables like audioquest diamond and audioquest vodka it takes some virtues of the cables with less wider images, it gives a s sensation of better clarity but in my case that clarity is out of place on my main system feeling artificial, but on my computer with the pro iDSD and a pair of amplified focal solo 6be it was not bad, but also it was not something amazing.
Most of my gear are on audioquest Niagara’s 1200 and 3000, maybe without the Niagara the effect could be more positive. As this is system dependent I can say the product works, but the result will be different from system to system, and user to user.
I my case is money lost unfortunately, as I destroyed the boxes and now I will have to keep them.
