Long ICs versus long speaker cables

I would go with the long ICs, I have done so when I was using mono blocks directly behind the speakers. As a matter of practicality I think that you can obtain good quality long ICs much cheaper than long speaker wire. I also have Cardas GR speaker cable and shudder to think of the cost in this length.

Hey,

I run very long IC's from my pre-amps to my 300b monoblock amps. The IC's are in the walls so they run for 40 feet at least... Bdgregory is right. The professionals that installed my home theater/stereo said it was definitely better to run long IC's than long speaker wire. My system is exceedingly revealing and detailed. The long IC cables have not detracted from those qualities at all.

Mucho gracious all.

I just sent Cardas email with regards to what George Cardas recommends. They said long interconnects and short speaker cables.

As Stanwal pointed out: the cost of long Golden Ref. speaker cables are very expensive; even at a used price, but so are the Golden Ref. ICs. Maybe this long segment will be Golden Cross or something similar instead.

Thanks again!

I feel your pain, my GRs were 1/3 price used and I still paid $850 for 2.5M pair. I don't have GR ICs, I use VDH as they are close but considerably cheaper for me. I would look at some other sources, my long ones are Audio Synthesis Silver Blue with WBT plugs. A version is still in production, you might check on them. See their website, they are a small company but make good things.

As was indicated, opinions on this question will be divided, and there is no unequivocally correct answer. I would add the following to what has been said, though:

1)The higher the output impedance of your preamp, the more important it is to have low total capacitance in the interconnect cable. That means either having shorter length or lower capacitance per unit length, or both. Most preamps will have low enough output impedance that this will not be a concern with typical cables, for a 6 meter run, but that will not always be the case, especially with some tube preamps or with cables that have high capacitance per unit length. If it is a significant effect, the symptom would be upper treble rolloff.

If you wish, let us know what preamp you are using and I can calculate some specific numbers.

2)Assuming the interconnects are unbalanced, longer interconnects can increase the likelihood of ground loop hum and noise problems, due to the increased shield resistance that results from the longer length.

3)Having adequate wire gauge is obviously more critical for the speaker wires if they are longer, or resistance may increase to the point of affecting the bass.

4)Capacitance is, in itself, usually unimportant in speaker cables, because of the very low output impedance of the amplifier. For long cables, inductance may become significant enough to affect the upper treble. Lower speaker impedance at high frequencies increases the likelihood of that effect being significant.

5)Skin effect losses in speaker cables may have marginally significant effects on the upper treble, depending on the cable construction as well as the length. Lower speaker impedance at high frequencies increases the likelihood of that effect being significant.

6)I don't think that there is a clear answer as to whether the fact that larger currents flow through speaker cables, as compared to ic's, means that the various cable effects that fall under the heading of "unexplainable" will be greater or smaller. A case could probably be made either way.

FWIW, assuming your preamp does not have particularly high output impedance, my instinct would be to go with long ic's/short speaker cables.
