Buying advice


I have an Arcam FMJ A19 driving a pair of KEF LS50s. Maybe it’s a tad, just a smidge, bright. I don’t even want to use that word because I know it’s audiophile death. Maybe it’s better to say that I’d like to take a step—just a step—in the Harbeth direction. Import a rounder, smoother, warmer sound into the mix. And I’m thinking that speaker cables might help. 

I’m constrained by a very small bank account and grave limitations on room correction. 

There’s a pair of Morrow SP2 cables for sale on this site for $66. The price is right but are those going to take me where I want to go? If not, any suggestions? Please keep in mind the constraints noted above.

Crazy paranoia: The Morrows are 10 feet long as opposed to the 6 foot length of my current Q.E.D. cables. (From Q Accoustics.) That extra length can’t possibly affect the sound, can it?
Thank you.

I do not like Morrows, the cheaper ones.  The ones that won awards I don't want to pay for.  I would suggest a Schitt Loki analog tone control as a cheap fix until your budget allows a better one.
A cheap tweak for too bright for your taste speakers is to double up the gauge of your current speaker cables.For example if your cables are 14 gauge,buy a roll of 13 or 14 speaker wire,cut it to length, strip the ends,insert in the holes of the binding posts,re tighten.It's not a cure all but it will take the edge off for the time being while you're researching other speaker brands and selling plasma to pay for them;-)
Arcam can sound somewhat "analytical".  Kef probably has a metal dome tweeter.  I myself have QED silver cables and they can sound bright.  So I can understand your system might have a bright sound to it.  

Honestly I am not sure a $60 pair of cable can fix that.

But if you really have to choose a different cable, I would go to the What HiFi review page and find an affordable pair of cables that can warm up the sound.  What HiFi has a lot of affordable cable reviews from across the pond.

I know that the speaker cables I’m talking about are very cheap by audiophile standards. But until the Arcam seller talked me into making some kind of investment, I was leader of the “cables don’t matter” army.

Wanna know something else? After I had them for a bit, the sound actually changed. They burned in! Another audio myth legitimized?

I’m still not quite ready to accept what I heard first hand, with my own ears. Science must be right and I must be the victim of some neurological prank. Otherwise, what do we have? Where is the science upon which our civilization is grounded?
a step in the harbeth direction would be to get harbeths, better more natural less hifi sound, for sure
