I am looking at buying some Van Damme Blue speaker cable (Studio series?) to go between a 100wpc amp and my speakers. How does the diameter of the cable change the sound? It's available in 2.52, 4mm2 and 6mm2. I'm thinking that for the longest run I have of 7m, that the 4mm2 stuff will be adequate. What would the 6mm2 do differently? Any ideas? I already have some 2.5mm2 stuff, even though it's in Bi-Amp form. |

The longer the run, the more current draw, 4 ohm versus 8 ohm speakers, bass extension, all demand thicker cable if you want to retain best performance. 7m is quite a long run for a speaker cable and that will require larger cable if you are not to suffer from losses.

I generally find a thicker core diameter brings sonic improvements.

I recently bought some 4mm for a 4m run from a 200w amp. It does not sound constrained.
Ages ago I used 128 strand generic cable after finding the thinner 78 strand a bit light weight sounding. You may decide to go 6mm is playing it safe better too much than too little eh? Of course the thicker the less flexible it is or easy to hide!

Hi I've been using 4mm van damme cable in my system for some time now... Have used many different cables over the years and no longer feel the need to upgrade?  I removed the outer jacket from mine as its 'very' thick, I then lightly spiraled the two conductors and sheathed them tightly in nylon stretch braid. The 4mm cable will have less resistance than the 2.5mm and may help in the bass. That said I would imagine the 2.5mm would be adequit over relatively short runs and would be a lot easier to manage. All the best Martin |

Is the "HiFi" shotgun version better for home use?

And if I used 6mm cable, what plugs can I fit in an Arcam amp?
4mm Z plugs, so surely the optimum size cable is the 4mm version?

I have found thick multi stranded cable can thicken and slow bass a little, not saying this cable will though.

I use 6mm stuff off eBay for about £15 for 10m. Works very well. I mess about with speaker wire and also use 4mm Supra. Don't notice much difference and the Supra was just the same price.
Think my next experiment might be some old Western Electric wire - spending about the same but it'll be much thinner and cloth covered.

Exposure Electronics.
Looks like Naim NACA4 and 5
Assume only available 2nd hand and very good
You could pick up a bargain if you can find it

Greetings, first post here, interesting site! One thing though, I don't understand how the longer the cable run is, the higher the current draw? I = V/R, or Z. If the voltage from the amp is 10V, the speaker has an impedance of 2 Ohms, that's 5A current. This is an extreme case next, add cable and connection resistance of 2 Ohm, with the same voltage from the amplifier, I= 10/(2+2) = 2.5A. The current is reduced, losses increase and the output to the speaker is far lower. These figures are only an illustration, the higher the losses are in the cable, the current drops. To create the same spl from the speaker, the voltage sourced from the amplifier must go up to compensate. Here's a great calculator for evaluating losses with cables. The cabling system at home for ancient KEF Reference 3's is a DIY setup 10 AWG (5.26mm) Silver plated copper PTFE 600V rated single cores, bi-wired. Length is about 10m. Amp is rated at 180W, speakers are nom. 4 Ohm. |

Good to have you here I'm no techie - longer cable means the amp has to get through more before it reaches the speakers. That calculator could help decide if a proposed run is ok or not. I switched to a Pre Amp with a remote so all the kit could be together and shorter cable runs. 'Course it turns out my existing speaker cable is a bit too long up there with the best ! |

This is of some interest as, when I finally manage to get the new lounge into operation, I will have what may well end up being a 7 or 8 metre run of speaker cables. I am lazy enough, in spite of having a remote on the pre, to not want to walk those 7 metres every time I want to change an LP or CD.
I'll be interested in your findings wonky.

I gave up as the the run was silly to get from the kit in one corner of the room to the furthest speaker almost opposite corner. Since the house refurb that is even longer and the cable would have to pass in front of a doorway. (Did prefer the kit beside me though........) |

I'm lucky in that, as the lounge is upstairs, I will be able to run the cables under the floor. The one concession to domestic harmony I am making is that the equipment will be in one corner behind the sofa. The speakers will be about 6 metres from the sofa. |

Concrete floor here and for some reason the other half was unimpressed with the cables running diagonally across the room  Considered a channel under the floor for the speaker cable, but this is now getting too complicated - plus what if I change speaker or even kit position ? I loved having the kit right beside me Now I realise if I want the real deal I need to be at the point of the speaker triangle. Makes a big difference 'Course that's not practical for everyday use. Needs more work there, last comment was "you're sitting in the middle of the room !" |

Looks pretty good value and they post to France. I'll watch it for later. |

There's always massive arguments about speaker cable so I've bought different types to make up my own mind - as I say it's cheap and sounds good. There's a fella on the bay that does finished runs as well but,on here,it'd be pointless linking that. I'm sure we all have our own wee quirks with connections!
If you do try it let me know what you think please.
