Creative Cabling for Bass Quality

I originally posted this in a thread about improving the bass quality of Legacy Classic speakers, but I suspect other speaker owners might benefit from what eventually worked best for bass with the Classics.

It all began with me feeling the bass of my Legacy Classics lacked a bit of definition. Tightening loose screws on the woofers, tilting the speakers back a few degrees, and playing with room placement all helped, but not enough (I also tried plugging the ports, as one Audiogoner suggested, but thought the bass sounded terribly constipated). I biwired, and that helped too, but not enough.

I next tried biamping and found that tubes so sweetened the top end I didn't care for awhile about low end imperfections. As luck would have it, my Proceed preamp offered stereo sub output, and allowed a setting of 120hz -- thus matching the Classics’ low crossover point. Assigning my McCormack power amp to driving the woofers alone helped tighten the bass too, yet I still wasn't happy.

Next I wondered if bass-specific wiring might help. I had been using high end MIT cables for all, but now decided to use it only for the mid and upper ranges. After some experimentation I reasoned that speedy silver for the bass end might help tighten things, so I tried Signal Cable’s Silver Resolutions, and wala! . . . bass did indeed tighten significantly; further, despite warnings from some, I noticed absolutely no synch problems from using different cables for lows and mid/highs. Thinking a cable with more silver might work even better, I tried 12g pure silver, but lost the quickness (and then some) the Signals provided. I surmised that the skin effect rendered those particular thick silver cables sluggish.

I put the Signal Cable Silver Resolutions back in, and for a time lived happily with that set up (i.e., Silver Resolutions on bottom, MIT on mid/top). But being an avid jazz listener, in due course I missed the bass "weight" that the Silver Resolutions sacrifice to get bass quickness.

Hmmmmmm, what to try. I wondered if thick, flat copper like that found in Analysis Plus cables might help, and since a pair of Oval 9s were selling cheap here at Audiogon, I tried them. Sure enough, they added major bass weight, but completely annulled the quickness of the Silver Resolutions! Grrrrrrrrrr.

And here's when the best thing happened.

I had ordered the Silver Resolutions terminated with banana plugs, while the Analysis Plus Oval 9s sported spades; the posts for bass on the Classics, of course, allow for both spades and bananas, so I hooked BOTH the Signals and Analysis Plus cables to the bass-end set of posts, and then to my McCormack.

All I could do was sigh with satisfaction when I heard it. Exactly the effortlessly quick and weighty bass I'd imagined possible from the Legacys. And now many hours of listening later, I am still unreservedly content with that cabling arrangement. The only tweaking thoughts I've had is trying Oval 8s if I ever see a bargain, and possibly trying silver ICs between the preamp and McCormack someday (I’m using Audio Metallurgy GA-0 ICs now . . . actually I wish AM would make some silver GA-0s, I think their magnetic technology is a very effective concept).

I have a question for the Pros out there... Fact is a speaker cable is only 2 poles, each of which might be as important as the other..

Positive, feeding the speaker, and the Negative coming back from the speaker to the amp.. I suppose that the Speed and recovery coming back is as critical, as you will see some specialty companies use an even larger gauge cable coming back off the negative tap to the amp.

Why? Because the ground should be a larger and more current capable device to keep the system damped correctly?

And this leads to the question, since all you guys are going as far as mixing cables of types to double up and feed the acoustic devices "speakers" and finding they have effect overall with the Gauge type, metal choice, and each can add or detract certain character...

Why would it be far out of league to make a speaker cable and interconnects for that matter, and maybe even power cords, that Utilize for example a POSITIVE leg of Copper with small content of silver at a fair sized gauge of like 12 or 11 gauge, and a bigger return cable NEGATIVE leg made up of a Speed cable pure silver such as 10 or 9 gauge? Or the opposite effect switching this config could be better? Big silver feedint the speaker and copper coming back? Who knows maybe this is a part of the secrete in these 4000 dollar cables and its as simple as that vs. all these off the wall geometries and things that they market..

Trade secret? 2 different wires completely separate feeding the positive and negative? Why not? Who says this would not alter the wants and the not so much wants of a speaker signal going in and having a different delivery method of metal or geometry coming back?

I suggest trying now A different cable on the input and output of the speaker vs. mixing them going in and coming out, as it would seem somebody could pinpoint this way what is really gaining the type of performance character desired on which side of the fence, and possibly debunk or verify if each leg is as important as the other and what is best used in and out, which could be completely different metals or gauge..

Now the other issue here is that I am sure most will say now your using cables as Tone controls running a Silver on one side of the signal and a Copper on the other altering its response to gain overall balance, but what I love in this argument is if you were not using a Cable as a tone control to an extent than what in the world would you be spending so much money on cables in the first place if you did not expect them to change the sound to your liking!! ?

Les3547,
This is the exact issue I question... What is the originating signal and how do you know its not sounding exactly as the originating signal with or without a Monster cable, a Cardas, or "insert cable here" with each different piece of gear? Fact is you might need more or less of something.. Again hence its a tone control method, otherwise why add, combine, or try any different materials!?

Who is to say that it is now because of this mix the correct sound? Who can verify that except for yourself?(meaning anyone, not just you in general)

Again nothing wrong with finding the sound you like, but if a CD is lets say "Thin" or "Heavy" or "Enhanced" you would never know what this supposed mythical muse of neutral, natural, or correct really is, especially if your proving this exact point and my point needing to mix materials and methods to get "Original Tone" because even if it is in fact "Original tone" and I can agree you have probably found it, what got it to that original tone? Thats right you said yourself your Cables did!!

Hence again, yes they are in fact acting as a tone control to fix or at least subtract any insufficiencies in the recording you are saying now sounds better, because the recording did not change, your cables did, so that did in fact change the tone in the end.

By the way I am not arguing but making a very clear point..

We are funny figures as audiophiles trying to prove that we are all just trying to do things "The right way" in the end we are altering and doing what it takes to make the signal sound good, not necessarily Right, otherwise we would not be changing anything if we could just leave it alone and say it sounds how it is suppose too, it took methods for you to get that tone, and it was thru several things I am sure with changing electronics, re-mastered recordings, and or Cables.

So getting the "Correct" sounding cables is here nor there, realistically and technically we are using them as a tone control in these methods regardless if we think they don't add or take color away like a Equlaizer or loudness knob...
