Upgrading speaker cables...

Back to the original question; you are better with one better set with jumpers than two pairs of a lesser cables. Just use what you have for now and make some simple jumpers of your own with some decent cable which should outperform the cheap jumper strips that come with most speakers; if you don’t hear the difference with this first simple test then likely your system/speakers are not revealing enough that tweaks are very noticeable but probably sounds very musical nonetheless. Not everyone has great hearing or knows how to listen or what to listen for; for many of us it takes years to learn how listen to hear the differences between cables and tweaks. If you do hear the difference between making your own jumpers then experiment with some better cables but be smart on what you spend. You can find a lot of nice cables used or have some fun building your own - VH Audio is one of several places to buy bulk cable. As several have said here, you have to listen with your own ears and not too much to us. Have fun, good luck and Tweak away. More importantly enjoy the music.

I Introduced Kimber to one of our local brick and mortar shops back in the 80’s and they still carry them today. I’ve owned both the 4tc and 8tc and good cables but there’s so much better out there and one doesn’t have to spend a lot to hear it. Took in a set of Clear Day Cables double shotguns for them to listen to, which almost every system they have on the floor has 4tc and the Clear Days destroyed them and one of the employees there has gone to Clear Days at home and a couple other employees have pitched Clear Days to many regulars that hang out there who have purchased many from Paul. No one there thought the Kimbers were even close and one person there admitted that cables don’t make a difference... well now he does. Blows my mind a shop pushes something and has bought the product they can’t carry. I really like Kimber and know they have a great product line as I’ve owned and still own some. Someone with a system getting up there of the price of nice luxury car should look into Ray Kimbers better cables, I think.... bet Ray would say the same.

As far as what one should spend on cables based on their system really depends on the quality of components. The OP equipment is fine and no doubt better cables are going to improve their system, but yes do not go out and spend $2,000 plus on a pair of speaker cables. My speaker cables are around 21% of the cost of my speakers, CD player with IC and PC is almost 100% and my player shines with my cables and I believe it would improve with cables costing more than the player. My amp I’m around 33% with IC and PC. Dedicated circuits and receptacles will only help and really required when the cost of a system goes up and becomes more revealing or you get to a point you’re just throwing money out the window.
