Thanks b4icu! According to your calculations and experience, in my case, would a wire thicker than #16 AWG actually hurt sound quality, or would it just be diminishing benefit?
How to select a good Speaker Cable
Speaker cables do have a significant role in how our system sounds. Different cables sound different.
So which one is the right one for you?
The Speaker Cable is an extension of the Amp. and not an addition to the speaker's load. It shall have a certain resistance (low) not to spoil the Amp's DF figure. As so, it can be calculated and there is a formula to do it.
The higher the Amp's DF, the lower the Speaker Cable's resistance shall be. As today SS power Amp's get DFs of 400 and above (Digital Amps go by thousands) the cable of 10 ft (3m) long, gets as thick as 0 AWG.
I can see your eyebrows elevates, when that thick cable is to be deal with. Most Speaker Cable makers skip it because of that. So most cables on the market (regardless of the look or price) are of 14-12 AWG. Way less that supposed to be.
Worst! no Speaker Cable maker, dealer or seller knows the answer, of what is the correct cable for your system.
So most of us ended up, with a cables too thin for the task.
A conducted test, on this site, about a year ago as well as with some closer friends, shows a significant improvement with a calculated size cable over their previous cable. The results were all positive and preferred the calculated cable.
So, instead of asking: which of two brands, or two prices or two colors of Speaker Cable do I need, you should ask how thick of a Speaker Cable do I need.
I'll be happy to provide you the calculation, for who request it. All you need to provide is:
1). Length (Ft. or meter)
2). The Amp's DF figure.
Thanks

@b4icu Your DF calculation, while doing no harm and perhaps optimizing one aspect of making a proper connection, is overly simplistic and has no direct relationship to the effects the cable inherently impresses upon the net sound of your system. To seriously think this is a panacea is laughable, bordering on delusional! I have used such theories and cable experiments for the last 40 years. I have also owned $20k cables. One size does not fit all...on the other hand, having a very small minded solution to a complex problem is naive and misguided at best. |
Mr.
qilin_maker The answer is NO ! It was tested with a system of a friend, using PASS LAB 250W power Amp, with calculated cables of #4 AWG. On an occasion I made a new cable of #0 AWG for demo, I tested it with his system (and a nice bottle of wine), replacing the #4 AWG, by the #0 AWG. Sound did not improved. I need to say that your DF is kind of low (40), so it really not the place to look for the sound improvement. Usually DF is about controlling the speakers. If so, the higher the better. To get the control effect with high DF Amp's a proper cable is required. |
Mr.
dave_b Regardless, if you have a point or not, till you won't offer a better solution, you practically have nothing. I also have more than 40 years of experience, but this "eurica" came to me only in the past 10-15 years. I did extensive tests and used this stage of Audiogon, to run it around the world: US, England, Singapore, Israel and more. I worked everywhere it was given a try. It started (naturally) with my own sound system (Klipsch Forte-II with CARVER TFM-35). Than I went with the same idea to a dear neighbour of mine, with a KEF Ref. and a McIntosh SS power. It had no improvement! That drove me to the drawing board and came out with a formula. The idea was, as just mentioned, tested extensively. So tests approved it works. What do you have? Nothing! |
I have a vast experience with actually owning more equipment and cables in various houses than can be dreamt of by your small....anyway, I have a world of knowledge in me that can be applied to various issues pertaining to audio. There are certain cables, for instance, that I have found to be more efficacious for the discriminating audiophile, which yield superior performance over a broad range of electronics and speakers. Admittedly, conversing with someone who has apparently committed so much of their energy pursuing an appropriately small idea, commensurate with the amount of understanding expressed regarding the effectiveness and performance of audio cables, is a recipe for disappointment. Enjoy the Lilliputian land of your own design and may the all and powerful DF yield rewards equivalent to the less than significant theoretical proposals you have made within this post. |
