Longest Advisable Speaker Cable Runs?

For Supra cables if you are in the US give these guys a call:

Sjofn HiFi

If you click the link you will see that these cables are not that expensive. The set I bought was $26/meter per pair (S/Ply 3.4) but for $12/meter per pair you can get the Classic 2.5 that are also very good. You need about 9m so if you go with the Ply 3.4 it would be about $250/pair and if you go with the Classic 2.5 just over $100.

As for OCOS, Dynaudio now represents them and you can call the directly for pricing. Yes they will be pricier, but again you can look for them used.

I guess another low cost alternative could be Blue Jeans cable. Many here on the forum seem to like that company.

There are two different configurations. I am familiar with the stepped attenuator remotes. I have them in two of my preamps. His configuration is very transparent for a remote volume control. John is a class act and would be more than willing to help you.

I'll look into both those options. The Bent Audio Attenuator may be a bit to ambitious-I'm not much of a DIYer but I'll check it out. I'll also look to Sjogn for a Supra Cable recommendation and price quote. You guys are awesome. Thanks for all the help.

Tony (Clio09), it looks like the shielded Ply S3.4 is currently $36/meter/pair, rather than $26.

Dave, if you go with a shielded cable, such as that one, you'll have to determine a circuit ground point on the amp to connect the shield (the "drain wire") to. Since your amp is described as having bridged outputs, the negative (black) output terminal carries a signal, rather than being ground.

Thanks for the correction Al. Need to use the calculator next time. Still quite reasonable for such a long run.
