Here's a few tips before going nuts trying to find the perfect cables.
make sure everything in your system and room treatment and speaker placement has been optimised.
Get all the basic stuff right first.
People spend a lot of money and time bouncing from one component to the next, and little or no time getting what they own to sound as good as it can.
Most tend to take the path of least resistance.
I don't want to say lazy, but, to get good sound requires a bit more effort, and expecting a set of interconnects to transform a system is asking too much and could be doing more harm than good.
Veiling out distortions with more distortions isn't the answer.
I had a friend sell of a lot of decent gear because certain records sounded harsh.He wanted everything to sound smooth.
I told him some recordings are just bad, and some are good.
If you bring them down to the same common denominator what good is that?
His response was-well everything sounds smooth.
I told him, no, everything now sounds worse, because the better recordings sound no different than the poor ones,hence a degradation in sound for the sake of sameness.
If I paid big bucks for a 45/ lp I would hope to get what I paid for.
It should sound better than most of the standard thin pressings from the 70's for example,not the same.
I wouldn't want an IC so coloured that I couldn't tell the difference.
Forget "warm" look for uncoloured cables.
