using a jumper cable - connect which set of post?

Try it, see which way you like best.
I am of the opinion that most info comes out of the tweeters, so the connection should go there

As can already be seen in this thread, opinions on this question will inevitably be diverse. Some people say to use the low frequency posts, some say to use the high frequency posts, some say it doesn't matter, and in past threads you will find some recommending connecting one conductor to the low frequency post and the other conductor to the high frequency post.

IMO, assuming that contact integrity is good and that the jumpers are reasonably short and of reasonable quality, whatever differences may be reported are neither technically explainable nor technically predictable.

I would also suggest you try jumpers identical to your speaker cable, you may find you don't need new biwire cables.

I have been running the direct connection to the low frequency post. I did try moving it to the high frequency post for a few days. It does seem a bit more detailed but also harsher as well. I have become accustomed to the sound from the low set of post. That is just what sounds right to me. Thanks for the thoughts guys.

I say hedge your bet by plugging your speaker wire into one up and one down post...and reverse them every other day. The distinction between biwire cables and jumpers is clear as it regards 2 wiring scenarios, but my main speakers (Silverline Preludes) sound better single wired with the supplied gold plated brass jumpers...more coherent, unlike myself. I was told by the speaker's designer that this was the case, and was also warned NOT to lose the jumpers as he would charge me for new ones. I assume he's replaced more than a few of these so he's not shy about the warning. I think wondering what posts to use for the main wire with jumpers is a classic example of the gonzo side of this hobby, along with claiming that the use of a one inch strip of your wire instead of a pair of thick solid brass jumpers would somehow make an audible difference...but then I like gonzo.
