Default Do RCA's Really Make A Difference?

whenever i buy rca's, i try and buy the best ones i can. crazy shielding and all that stuff. my question is, am i a sucker? do the rca's really matter all that much? besides the obvious physical differences in terms of looks, are there noticeable differences? sound quality or volume wise? the reason i ask is i'm going to be placing an order once i measure up the length i need from my jbl ms8 to my amps today and want to know if i should bite the bullet and spend $30 or $40 or just get some cheapo ebay special rca's since they shouldn't be longer than 3 or 4 feet anyway.

I’m so sorry, but I do not buy into 90% of the hype brought to us audiophiles by the commercial sector of our hobby and the home entertainment industry at large. My brother, an audio engineering whiz kid has proven to me what is real and what is not. Let me rehearse with you an example of how he does this.
We gathered up a 5 of our audio buddies. We took my “old” Martin Logan SL-3 (not a bad speaker for accurate noise making) and hooked them up with Monster 1000 speaker cables [ed. Monster Ultra Series THX 1000 Audio Interconnects] (decent cables according to the audio press). We also rigged up 14 gauge, oxygen free Belden stranded copper wire with a simple PVC jacket. Both were 2 meters long. They were connected to an ABX switch box allowing blind fold testing. Volume levels were set at 75 Db at 1000K Hz. A high quality recording of smooth, trio, easy listening jazz was played (Piano, drums, bass). None of us had heard this group or CD before, therefore eliminating biases. The music was played. Of the 5 blind folded, only 2 guessed correctly which was the monster cable. (I was not one of them). This was done 7 times in a row! Keeping us blind folded, my brother switched out the Belden wire (are you ready for this) with simple coat hanger wire! Unknown to me and our 12 audiophile buddies, prior to the ABX blind test, he took apart four coat hangers, reconnected them and twisted them into a pair of speaker cables. Connections were soldered. He stashed them in a closet within the testing room so we were not privy to what he was up to. This made for a pair of 2 meter cables, the exact length of the other wires. The test was conducted. After 5 tests, none could determine which was the Monster 1000 cable or the coat hanger wire. Further, when music was played through the coat hanger wire, we were asked if what we heard sounded good to us. All agreed that what was heard sounded excellent, however, when A-B tests occurred, it was impossible to determine which sounded best the majority of the time and which wire was in use. Needless to say, after the blind folds came off and we saw what my brother did, we learned he was right…most of what manufactures have to say about their products is pure hype. It seems the more they charge, the more hyped it is.

Unless you don't use KNU RCA's you're GOLDEN!!!
I have their Kolossus 1/0 (100ft) but when I tested their Krystal RCA cable I was shocked that it did poor, honestly our $2 RCA performed way better, we have tested it (Krystal) just for a reference only!

Now I have the high end Taramp's RCA cables they are silver and you can see the wires through the jacket for me they are great and didn't picked noise as the KNU did,

Good Luck,

I agree don't go to Over-hyped and Over-priced brand but don't go CHEAP at the same time!



Kindest Regards.

i've used knu rca's before. total waste. 2 of the 3 gave me trouble. lately i've been using xscorpion qsp rca's and i love them but at $12 a piece it's a little much for such short lengths.

i always read about how much of a difference rca's make, but i've used everything from rockford, stinger, knu, monster and god knows what else and can't say any particular brand has ever made my stereo sound better or worse.

In 1998 I had two identical cars {both mine}and one had cheap rcas and was loud. the other, I spent $60 for a 2ch Monster cable RCA and it never got loud [coincidence? I think not]

I personally like shielded RCAs because the thought of them being shielded and blocking radiated noise comforts me.

I currently use Stinger Hyper RCAs
and I have been very happy with them.


but I also had an earthquake 4ch give me alternator whine using the stinger hyper rcas.

the whine left when I replaced the 4ch with two 2ch earthquakes

Biggest problem i have had is failures to connections. Best bet buy wire and connectors and make your own. If a connector ever fails just replace connector not the whole cable.

I've had cheap rca's and $100+ rca's. Only difference is the more expensive rca's look better.
I have shca rca's now and like them. Look good and fairly cheap.
