 Topic: headphone re-cabling??Posted: 01 Jan 2010 at 1:18am |

thought i would ask this on here rather than head-fi (so that less people think i 'm an idiot
 )
other than the obvious changes (impedence), what else can be altered/improved by simply re-cabling?
i am trying to "make sense" of all the money which is spent , by some, on this.
my denon d7000s are 25ohm. i recently bought a 125ohm adapter (partly out of curiosity and partly because i wish to buy a tube amp in the future)
i have tried this adapter with my denons/solo srg. apart from the obvious need to crank the volume a tad, i cant say there is any difference at all.
which brings me back to my main question.
cheers folks

Hi Oldson, first IMO the Denon's sound better out of a SS amp. I know it is a very generic assertion but based on lots of amps I tried them out of I found that SS tend to drive the Denon's better. Of course there are exemptions and some hybrid amps like the Musical Fidelity X-Can V2 and HiFiMAN EF2 and EF5 do well. My highly modified Singlepower MPX3 struggled to drive the Denon's w/ 6SN7 tubes, however w/ a 2C51 or 6CG7 in the driver position and a pair of 5687 on the output position the sound was very good.
Personally I feel the SRGII or the Rudistor are better options neither better just an slight different sound "flavor". Considering the Solo SRGII sells for about half guess which one I would choose?
 As far as re-cabling I have heard the Denons w/ their stock cable and two different re-cables, a 22 gauge Jenna and an XEV from Zynsonic (silver plated copper). The Jenna was a bit more open and mellower w/ an slight deeper/thicker bass. The XEV had a better defined and crisper top end and since it cost less than 1/3 the cost of the Jenna I went with it and do not regret the decision.
Good luck in your search. BTW, before spending money on a re-cable I would opt for an SRGII, the leather pads offered by JMoney which work beautifully, and the MarkL mods.

thanks for the reply.
but i obviously did not explain my question too well.
forget the sound changes.
i was wondering physically what the differences are between the stock cable and any given alternative cable? electronically.
for arguements sake:
we know the denons with stock cable are overall 25 ohm impedence.
if i were to change the cable for an alternative that made the overall impedence 150 ohm (for example).
would the affect on SQ be any different than using stock cable with my 125 ohm adapter?
i appologise if this makes no sense.
i just fail to understand how a different cable can change SQ, in any way other than a change in impedence.

Cable in itself cannot change the resistive component of impedance... copper wire is a good conductor, and so are all metals used for electrical connection.
Therefore recabling cannot alter the resistive impedance (in Ohms) unless that cable includes a resistive element. However, capacitance will differ between one type of cable and another. Capacitance does not affect the performance of headphones, it affects the driving source they are being driven by. If that source is an attenuator from a speaker amplifier (the break jack found on some amps), the capacitance attenuates the highs (most likely beyond the hearing range unless extremely capacitive) to one degree or another depending on the value of that capacitance and the value of the attenuation resistor network in the amp. If the source is a dedicated headphone amplifier, the capacitive load will affect the stability of the amplifier. Some amps could go unstable, or on the edge of stability, causing excessive ringing on notes. Other amps, such as the Novo and Solo, being highly stable, will not ring, but the cable can have that many "cancellation nodes" that the subtle high frequency information that makes things sound open and airy, can be lost. The world offers that many choices of cables in hi-fi (of all types) that no man can ever know what's supposed to sound right anymore...  |

You make a good point - who's to say what sounds "right". If it puts a smile on your face, doesn't fatigue and gives you a regular rush, I figure it sounds right. Otherwise it's chasing rainbows.
Back to the other point ... Is cable inductance not also a factor? |

I think it worth clarifying that resistance and inductance a not the same thing.
Adding a straight wire with a certain resistance will not change the inductance of a headphone. Making a coil out of the wire will (in my view). A cable change can (in my view) change the apparent frequency response of a headphone due to either a change in resistance and or capacitance of the cable. I have found that changing cable material and structure always has a greater affect than changing the length of an existing cable. I am not inclined to ever put additional resistors or inductors in line with my headphones. I put additional capacitors in line with my iMod to protect DC damage to downstream amplifiers. Adding a resistor does not change the inductance. Incoming!! I'm bound to get flamed now. [no you're not!
