Any cable delivers more bass than Cardas Golden Reference?

Same set here too.

I think once you get to a certain size wire gage all the rest is $$$. What I have found is the components in my amps are made to a manufacturing tolerance that allows audible difference in output. I have also measured many speaker drivers and there is variance there too. Everything has a manufacturing tolerance and those capacitors in your amps for instance are probably no better than 5% +- and probably 10%. So two amps from the same company made on the very same day can and do sound a bit different because when you add all the tolererance deviance up you have different output. They call it tolerance stack up and as long as it does not exceed a certain level they will sell it to you. This will effect sound volume and bass and treble output channel to channel and if you are bi-amping as I am there is a difference from the left channel to the right channel amp output. I have two amps and a two way two channel system so there are six components with different tolerance output to be integrated for best sound.

To balance the difference in your speaker drivers, your amp output and room acoustics I use a Xilica xp3060. It will allow you to compensate for unbalance and bass and treble and pretty much anything else. Above and beyond correcting these the Xilica will also allow you to flavor output to taste as well. You can save specific EQ settings for various types of music you play and recall them when you want for your current music of choice. You can also time align drivers. I figure the vast majority of all the cables sold are solutions looking for a problem and that problem is you keeping your money. Do a room EQ and find out how the acoustics of the room effect your speakers. There is a lot going on and until you get to the point where you can actually start to analyze what you are doing and correct what you have to work with cables wont amount to a hill of beans. Why throw bits and pieces at something when you can do this and analyze each step along the way to see if it works. Room Equalizer Wizard or REW which is free + one calibrated measuring mike from UMike and one laptop and you can begin to learn how to determine what your problems really are. It’s not simple set and forget if you want the best possible sound from what you have unfortunately and the very last thing I would worry about is cables.

3 things

* can you upgrade the internal wiring in your speakers? Amazing how patyhetic most are

* If your speakers can be biwired, try bass specific cable, like WireWorld has

* If only one binding post then try WireWorld Series 8 speaker cables

... I've got vintage Gershman Avant Garde RX-20, which have ample bass - but I wanted it to be more tuneful and well-defined. So I added a pair of PS Audio Xstream Statement SC Power Cords (one onto the CD a vintage Marantz SA-8001, and one into the JOB INT),  and made my own speaker cables from 12g Solid Core Copper wire, and am using the bare ended and biwired... I now have ample well-defined tuneful bass. Listen to the  CD 'SO' by Peter Gabriel, and the 'JUPITER' CD from 'Stadium Arcadium' by the Red Hot Chili Peppers - these both have really good bass to compare your system with... 

Interesting thread, especially with OP's lifelong music production career, and IMO,

PROOF, every tweak is an altered reality, imagined or perceived, emotionally preferred.

Measurements: techniques exist to generate control source frequencies, send to a cable, measure the output from the cable, any alterations at 10 feet, 30 feet lengths? Into this crossover, reactive? Crossover to this driver? .... Endless ...

I inherited my Horns and 15" woofers (made in 1956) in 1973. The first time I opened them up, I was shocked to see the tiny wires connecting the input terminal to the crossovers, tiny solid cord bell wires also to/from the Presence and Brilliance controls. It gave me a perspective about cables for sure.

Getting there, distances, time alignment, perceived differences, ???

When younger, reading, listening, yapping, I chose to believe the theory of multi strand, small solid core wires, individually insulated, like old bell wire, like the wiring inside those speakers. Short runs: I used 4 wire tel cable. Longer runs, 8 wire Cat 5 cable (current). Something about the time alignment of signals on the periphery of the wire compared to the center of the strand, multi strands not insulated from each other ...., thinner better ... I chose to believe it, stopped reading about cables ...

My preferred altered reality: tubes, horns, iron law large woofers.
