One of the first things I did was to remove the metal jumper plates and replace with jumper cables made from the same speaker cable I use. I find the standard metal links are usually a very limiting factor.
Interesting...but in the case of the Q300s they do not have a metal jumper plate but a dial (per pair of terminals) that open and close a 'link' which I presume is an internal metal plate 'equivalent'. Most probably open the 'links' as if bi-wiring and then use jumper cables...just to see if there is a difference...and also try connecting Red to Treble & Black to Bass...again, just to see if there is a difference?
Could make for an interesting session.
Anyone else tried all of this yet on Q300s?

Over the years I've tried all these variations and these days just leave the supplied metal jumper links in.

Ah good! I'm selling my kef speakers on ebay and have lost one of the inch bits of metal and replaced it with high quality speaker wire! So I can charge more! thanks!

Incorrect, dude; the inch of speaker wire is worth more than the speakers, thank you (I got it from the door bell of my granny's house)

It should not make any difference which ones you plug the cable into. Do which ever looks nicer / satisfies your OCD

As I understand it, the jumpers stay in. But you put red in the red treble hole and black in the black bass hole. And the theory is that somehow, although they're connected by a 1 inch bit of metal, so in electrical terms it's the same pole, it seems to sound better. Not sure I can tell the diff but from today onwards that's how I've got it wired so my guests can appreciate it.
OK, I think I get it (instead of connecting both Red & Black to the LF (Bass) terminal pair the Red is connected to the HF (Treble) terminal with Black remaining where it is). But from what I have been reading elsewhere there is a suggestion that the "1 inch bit of metal" are replaced with short jumper cables made of the same cable as used for the speaker cables, i.e., linking RED HF & LF and Black HF & LF separately. Apparently this improves the sound even more?

I think i'm going to have to buy some jumpers to try it out.. TQ blue terminated £25 delivered TQ Black terminated £85 delivered... As much as I want the matching jumpers I only payed £150 for 4 metres of the stuff!!!!!!! Will report back

There are now two threads running on the 'front page' on subjects that have no engineering basis whatsoever - interestingly with many of the same participants.
Now my knowledge may be 20 years out of date, but I can see no basis for changing my mains cable, or getting rid of metal jumpers. If anything, replacing a nice thick metal jumper tightly clamped under a binding post with a length of cable can only increase resistance (if only marginally) and thereby reduce sound quality, not improve it.
Now I keep an open mind, and if anyone can link to real study (not a group with an axe to grind such as a mag selling advertising or a cable seller) that can show that either a different mains cable or fiddling with speaker jumpers makes any difference, I wil eat my words.
Otherwise, I am afraid the same suggestion bias that makes enthusiasts rave over speaker cable / mains cable / interconnects is at work with jumpers.
I think you are missing the point. If they have heard a difference, and are willing to pay lots for extra/posh cable and are happy with that then thats up to them.
I personally have not heard any difference with power cables, posh Interconnects or speaker cable so I dont spend the money on it.
I have not seen any technical explination on why a power cable that provided it was up to CE standard would make any difference, same with any other wiring, USB and digital interconnects for example.
Audio / Hearing is entirely subjective.
I think you are missing the point and it is you who are trying to hijack this thread and turn it into a cable debate.
Read the OPs first post again. He clearly states that he has heard an improvement by wiring up his speakers with jumpers he already owned, in a manner which his friend suggested. He wants to know if anyone else has found this.
Agreed...all the majority of the contributors are doing IMHO are expressing interest, checking understanding, gathering information, etc., on what was stated in the OP...and I am sure that some of us will be off to try this to see if there is any difference when this is applied to our own systems. I personally have an open mind re. this and if it works out that it does improve the sound on MY system then excellent...but if not (but others say it does for them) then there is nothing lost other than a small amount of money (in comparison to the cost of the system...in most cases).
Back to theorising...before the experiment.
No intent to hijack, just pointing out the similarity in posters on the two theads and the underlying subject's lack of engineering basis. Please ignore any comment made on mains cables.
You made the comment that you have been gathering information and checking understanding. What do you understand the effect to be of replacing metal shorting jumpers with speaker cable?
And there was me thinking you were not going to turn this into a cables debate!
