After some tests I decided to sell the Sky, I have tried other copper interconnects (the Sky is silver) that I had on loan and they have given to a system tonal balance and timbre are very close to what I want.
The silver (in my system) makes the mid-high frequencies too aggressive.
The choice is between "Audioquest Colorado XLR interconnects + Oak speaker cable" and "Cardas Golden Reference XLR interconnects + G.R. speaker cable.
The Cardas choice would be "blind", I've never heard a Cardas cable except a Twinlink power cord, and I know the Audioquest copper cables, possessing the Gibraltar and having already owned the Colorado RCA (now including the XLR version).
The fear about the Golden Reference is that low frequencies are too swollen, and that the wires cutting through the high frequencies will sound euphonious and not neutral.
I was told this in particular regarding the RCA interconnect cable.
Do you think this is true?
I would like to sound neutral but rich, not "dry".
Soundstage! said the Cardas Golden Reference is really neutral, not giving that thin and washed out sound that audiophiles often think it is neutral, those who know these cables can confirm?
@ Ghepardbuster: you said about the Oak compared to Gibraltar: "Wider soundstage, better sense of space, more resolving."
Usually these features are achieved with a sound more subtle, more open, with more treble and bass drier.
It happens just that going from Gibraltar at Oak?
With a copper interconnect cable (I'm trying to Oyaide Tunami Terzo XX) and my Gibraltar I'm quite happy, I would like something more in terms of extending the frequency extremes (the Terzo is not very extended and refined) from the interconnect, and a speaker cable that is overall better than Gibraltar and not move anywhere the tonal balance.
