looking to replace Fyne speaker jumper cable

Dekay agree. Iam using the Jumper per Nordost instruction. It work well for my Redrose monitor and Diapason speakers and my wharfedale speakers.

I've tried these and found them a very nice improvement but always preferred 2 sets of speaker cables. Yes a lot more $$$

@roxy54 - "Purest" indeed.  Thanks mom.  😊.

I have not been a user of Purist Audio cables for 15+ years.  The product line was lacking resolution and too soft on the top.

Rather than spin your wheels on this jumper quest, consider trying a different speaker cable altogether.  The Wireworld product line is a good suggestion.  Another is Silent Source.  I just sold an 8' Silent Source Ref speaker cable pair for $2100. It has a bit of a mellow presentation but its tonal coherency is outstanding ....... and it's construction is silver wire.

I replaced the Tannoy jumpers on my Kensingtons with Transparent’s mid-priced jumpers.  More improvement in SQ than I anticipated.   I use mostly Transparent throughout.  

Bi-wiring sounds like a good alternative to completely avoid the issue, but if using a jumper, just know that some claim that pure silver is one thing, but silver coated copper is another. I’m not an electrical engineer, but some claim that silver coated copper cables can cause phase shift issues at certain frequencies. Would a 4" length really cause any noticeable change? Maybe not. But just be aware of that "possibility".
