DrewDunnI totaly missed the bit about frequencys going down diferent cores, just spit out my drink.

DrewDunnThank you for sharing your opinion. What equipment did you use to hear the difference?

CEntranceI use a Sony SCD-XA777ES SACD player, a Carver C5 preamp and a pair of Carver TFM-15CB amplifiers, bridged, driving a pair of Acoustat 1+1 Medallion speakers. The amps and speakers have new Nichicon and WIMA caps and the amps have dual full wave discrete bridge rectifiers to increase their power handling because of the speakers' reactive loading.
And, as I said, 54 year old ears.

DrewDunnLook at that! There are people out there who say that all capacitors are equal, and that opamp rolling is pointless, and that CDs sound just fine (we cannot hear above 20kHz) and lastly, that Biamping is a waste of time. And yet, look at your impressive system! There must be something to gain from that last 1% :)

CEntranceI'm not sure what that has to do with your cables. I own what I do because 20 and 30 year old hifi gear is cheaper than new, especially if you can buy it broken, then repair it with just a few new caps and a rectifier.

DrewDunnJust like yourself, audiophiles with a trained ear appreciate the added benefit of having fine components in their systems. And while you consider that capacitors make a difference, others consider that a well-designed conductor makes a difference. Our cables make a difference for hundreds of people who are happily enjoying them. And that's the truth .

CEntranceI think that you miss my point. I replaced the capacitors because they were defective, not because they provide some esoteric sonic benefit. The capacitors are electrically required in the amplifiers' rectifiers to smooth power and to provide transient power delivery, which is something that I think any audio equipment designer would know.
I used Nichicon and WIMA caps because they are low in inductance and equivalent series resistance, which, in turn, lowers the RC time constant of the circuit, increasing the rise time of their charge/discharge cycles. They're also relatively inexpensive in small quantities. This is just basic electronic theory - no golden ears required.
I'm still interesting in learning how your cables cause the signals to travel on different wires according to their frequency content, absent any active or passive filter elements.
And I don't doubt that your customers enjoy the cables. They appear to be robustly assembled and are very attractive. I'm sure that I would enjoy them too.

DrewDunnWhile this thread is good for a brawl, regretfully it might not be the place for a serious discussion. Email info at centrance dot com and I will explain what actually happens on the physical level.

CEntranceConsidering you have done nothing to do away with the mountain of doubt which is piling into your front yard, I think you might owe it to everyone here to explain exactly how your cables are a cut above the rest and are worth the (quite frankly, ludicrous) premium. While we may not be electrical engineers, most of us are at least moderately intelligent and can piece together enough information to produce an informed opinion.
Also.. 1 commited, 0 sales. This may be another good reason to prove everyone wrong.

patriotbarrowFrankly, I'm more appalled that Massdrop is giving a platform for con-men to peddle their snake oil. Taking advantage of folks with more money than sense isn't anything new, especially with regards to audiophile equipment. I would like, however, that Massdrop maintain some integrity and not give obvious clowns the means to do so.

NecronomoticonCEntrance did have a drop on one of their portable DACs, which wasn't half bad, to be honest. Maybe Massdrop based this drop on their reputation.

The designer claims that the 12AWG inner core carries bass frequencies, while the six outer stranded cores carry mid and high frequencies. Absent a crossover network at the source, how can that be? The electromagnetic signal has no intelligence - it cannot choose the wire that it will travel upon. Without some filter system to shunt the signals to the particular conductors, they must travel on all of them. The full electromagnetic spectrum that is transmitted from the amplifier will be present on every wire in the cable.
It's easy enough to test. All one must do is connect an oscilloscope to the two "different" signal paths. According to the statements made in the product description, only the "bass" frequencies will be seen on the center core and only the "mid" and "high" frequencies will be seen on the outer cores. I guarantee that you will see an identical distribution of frequencies on each set. Why? Because if the opposite were true, it would obviate the need for crossover filters in our speakers - all that would be necessary would be wires of different gauges; the signals would sort themselves onto the correct wires based upon their frequency content.
I think that the skin effect issue has been well-covered. The suggestion that our ears are sensitive enough instruments to detect the difference between .0127 ohms and .0134 ohms (the difference between AC and DC resistance in an eight foot 12AWG cable at 20KHz) stretches ones credulity, but I only know what I hear. I do know what I can measure, though.
As to whether or not this is a good cable, well, other than one sour note on the state of the terminations, it appears to use good-quality copper wire and banana plugs. The cables look nice. There's nothing in the description that would lead me to think that they do anything to negatively affect the audio signal. The components have a cost and it certainly takes time to put everything together, package and distribute it. I'm not an accountant or an economist, so I will live the value consideration to others.
Edit to add:
I'm not participating because I've already purchased wonder-cables that use OFC, single crystal copper, with a miraculous RLC network that induces pure audio clarity. Seriously. And I can't tell the difference between it and the Monoprice cables that I use on another system. Of course, I also have 54 year old ears and I'm saddled with the preconceptions of being an electrical engineer. So take that for what it's worth.
