Due to how subjective the topic of 'improvements' offered by various cables can be, I would not normally comment, but I must admit to buying a couple of pairs of these cables and have found the improvements gained in my system nothing short of amazing. I was VERY surprised. A much clearer presentation throughout and the bass is no longer flabby and boomy - it's taut and precise. Initially I was concerned that the cables had resulted in 'brighter' sound which was not to my taste at all. But even after just a couple of hours in getting used to the sound I have decided that IMO it is without doubt vastly improved.
