Speaker Cable Compatibility with Amplifier and Speaker


I have heard that it is most important to match speaker cables with the Amplifier being used; more so than the speaker. I plan to connect a Krell Evo 302 to a Harbeth 30.2. I would appreciate responses from anyone who is familiar with the science of selecting a compatible speaker cable for this equipment.

By science, this implies math, publications and peer reviewed publications of which I've never seen any.
I do think I have heard differences, but calling it science or most important oversells the place we are at.

Room treatment is always going to yield more reliable improvements.

Canare 4s11 is good speaker wire. They provide some specs of their products.

That’s a new one to me. The whole idea of matching with cables is based on a false premise. The idea is that nothing is perfect. (True.) So what you are supposed to do is match up components with flaws that compliment each other. A speaker that is bright or forward is matched with a cable that is more mellow or laid back. That kind of thing.

This is where cables get the bad reputation of being tone controls. There are lots of crappy cables and they can indeed be used that way. Actually most of them are bad enough they pretty much have to be used that way.

This whole concept of matching this way is what I call the band-aid approach: the problem is still there, you just covered it up. What makes it hard to learn is you really can build a pretty nice system this way. Only problem, when you want to upgrade something, every really good component you try is only going to reveal all the flaws you have built into your system. Its a recipe for constantly upgrading.

Please notice how many audiophiles are constantly upgrading. There’s a reason, and now you know what it is.

A better way to go about it goes like this. Your Krell and your Harbeth, they each have their own individual set of strengths and weaknesses. Your job is to find the cable that best illuminates all their strengths AND weaknesses. The cable that best reveals everything they are doing. As well as everything else in the signal coming down the line from your source.

Once you rip the band-aid off and shift to this perspective then its real easy to realize the best cable is the best cable, period. Does not matter what amp. Does not matter what speakers. When you upgrade, no matter to what, you will be happy because the same wonderful properties in the cable that shined a light on your Krell and Harbeth will now shine a light on the new gear. You will be off the audiophile treadmill. Hardly ever will you be disappointed with a purchase. You will be happier and more pleased with your system as the years go by.

Or you can listen to the system matchers. The choice is yours.
There was a time when you could buy an upscale loudspeaker cable that would drive some amplifiers into oscillation serious enough to cause component damage.  The cable designs were suspect and to a lesser extent so were the amplifiers involved.  I don't think cables like that are readily available anymore.  I think now you can just pick a cable that uses connectors compatible with your amplifier and go from there.
A Bryston owner wrote an article about cables used in your system.. It was very interesting read.. I saved it for reference but dang I can't find it.. duh.. So  this is from memory,, all cables need to be the least resistance possible.. When it comes to capacitance and inductance -- speakers perform best where the speaker cable has very low capacitance.. Interconnects need low inductance..  Follow them rules and whatever cable you pick you should get very positive results.. If you want you can find cables with exotic materials that follow these specs for better performance.. You want to test this theory ? Buy a pair Mogami  cables.. They follow this rule, they're super cheap, and they sound great !!!
Canare is another company that uses this rule
