Newbie Q: speaker cable length? Different OK?


Hi. This is a complete newbie question. I've ordered two 10' amp to speaker cables, but I really need 15' on one side. Monoprice (for better or worse) is willing to RMA the cable(s). Should I go with two 15'? Or is simply swapping out one 10' perfectly acceptable for signal?

Hi Donzi ..... I made an error in my last post.  The lengths I'm using are 6 feet for the left speaker and 9 feet for the right. As far as your second question, I definitely recommend your looking into the Speltz anti-cables.  Terrific speaker wire without the inflated cost of a lot of the other stuff out there. Lots of discussion about anti-cables on the internet .... search around and have fun ! For my personal taste, with my equipment and in my room, everything just simply sounded better when I replaced the AQ's with the Speltz wire.  For an excellent answer to your second question, give Paul Speltz a call.  You can learn a lot by speaking with him about your own particular concerns.  He's a great guy.  By the way, I have absolutely no affiliation with him or his company ... I'm just a very satisfied customer.
Adam, I did check out the website, then called. And you're right, he's a great guy. Talked at incredible length, and he seemed to be in no rush to jet me off the line. I ordered speaker wire today, Level3. Ironically enough,  went with two times eight feet. I figured out a different amp placement that's in the middle. So the whole question is no longer an issue; although you're right: He did say no big deal -- although only with HIS cables, no big deal. Thanks again for that lead.
Hi Donzi ..... Congratulations !  I'm glad to have been able to help you out.  The Speltz Level 3's are supposed to be really great wires, and I'm sure you'll be happy.  Please post your impressions once you've listened to your favorite music through your newly connected system.
OP, sorry I'm late to the party, but my 2 cents would be I don't understand why anyone would purchase speaker cables longer than what is needed.
For example; my amp is approximately in the middle of my speakers. My speakers are about 7' apart. My cables are 5' each.
From your initial post, how are your speakers setup to require 25' of total cable length?
@adam18 Sorry for the late reply. I'm reviewing this old post, and realize I never answered. You'll find this interesting, I've also become a huge Paul Speltz fan. I love the setup I have now, and the speaker wires. But what is interesting is that I upgraded the RCA interconnects (and only Series 1). And at that point the whole system came alive -- just on that IC change. I imagine that was the last of the weak links. One of my audio sources, TIDAL lossless streaming, has a section of their website to see if you can pick out which A/B choices in each the six samples was the lossless example. Try as I might, I could never hear it -- until the installation of the Level 1 IC's. At that point, I instantly heard six out of six. So yeah, thanks tons for putting me on to this
And @markeetaux , at that point, I had the amp set up in the right-hand side of an entertainment center, and because it was mounted there up high, it took about 5' to go to the right speaker and maybe 15' from the left. Shortly after this point, I decided to relocate it to a different section of the center, in the middle (down low). So that whole "different length" thing was resolved in favor of two 8' lengths. Thanks all.
