What is your approach to system fine tuning with cables and cords ?


Everything already sounds quite good, no obvious weak links.

PS:

I use the rack mount version of this inexpensive strip for the wall warts:

or

They filter noise down to 3 kHz, and have great surge suppression. If you use them for the little noisy adapters they add one more filter between your main power conditioner and your analog gear and DAC.

Inna it is great to be at that point. I am now, but it took about three years after I replaced some very old stuff, and one thing leads to replacing another and so on. Now at about a year with magic dialed in my system. I think is is great fun to try different cables and cords and other tweeks. To me it is like me upgrading my guitar when my guitar already sounds fantastic. So I don't feel any compulsion to do so but I do enjoy doing it at times. I have no system other than trying to figure out what is the weakest link in my system. Many times it is the oldest piece I have that wasn't picked specifically for this system, but my previous one.

>>>>>My approach was to get rid of them. No more speaker cables, no more interconnects, no more power cords. Not only no weak links, but no links period. 😛

No more pencils,
no more books,
no more teacher’s dirty looks.

If thy eye offend thee pluck it out.
Started making my own power cords and speaker cables.
Time to have a crack at interconnect next.
Did make up a new TT 5 pin din to 2 rca cable for my Denon, seemed to work out ok.
Then I only have myself to blame if it sounds like crap...... 
If you haven't spent the better part of a weekend moving your speakers a quarter inch here a quarter inch there while toeing in a degree or two at a time, then you haven't even met your weak link.
