Speaker cable for Nad 7050 and KEF LS50


I've been using cheap speaker cables to connect my LS50s to my NAD D7050 and they sound great for my uneducated ears. I have never really invested in cables, but I was wondering if anyone can recommend/suggest any (not very expensive) cables that could make a difference.

The QED Silver Anniversary XT is an excellent budget cable and one that I have used for the past 8 or so years with a NAD 320BEE int amp, Outlaw RR2150 receiver, Prima Luna PL2 and PL5 tube amps, Rega Ara monitors, Omega Super T monitors, Opera Platea floor standers, and Ascend Acoustic Sierra One monitors.

I just recently upgraded to Clear Day Cables based on a recommendation from someone on Audiogon. Depending on the Clear Day product, the cables are several times more expensive than your QED. For me, that increase in price to Clear Day cables, resulted in a sound that is more musical, more focused, and still a touch warm, which I find very enjoyable. It is akin to a veil being lifted, especially for the lower frequencies.

So, the QED will serve you well and it did me. But I did find a more pleasing cable for more dollars.

Thanks all for the thoughtful replies. Based on your comments I believe I will keep my cables for the time being. As I said in my first question above my system is sounding great. Since I don't have much experience I was wondering if I had bought really bad cables and this could have been hurting the sound, but this not seem to be the case.
It's simply personal preference. QED is a quality cable, that some listeners like and some do not.
It appears that your cables are very respectable. My only comment is that QED is silver plated copper and you may find that a stranded copper conductor may have a warmer presentation. Or a single copper conductor such as Audioquest may be more to your liking.

You need to decide what kind of change, if any, you are looking for. Most will say that cables should be transparent, but in reality certain cables may colour your system in a desirable way.

And with cable selection, it's trial and error to find which is best for you.
