A double run will sound better...though cost much more...but you should at least get matching jumpers, and it will sound much better than with the stock ones...
Nordost reference jumpers vs second set of cables
Hi,
My sound system is finally almost complete, and it sounds incredible. I just got a pair of PS Audio BHK300 amps for my B&W 803 D3 speakers. These amps have 2 sets of binding posts to go to the speakers. I only have one pair of speaker cables, so I tried using both cables on one amp, with one going to LF and the other to HF, and it obviously sounds a bit qbetter than using the B&W stock jumper cables.
The cables are Nordost Heimdall 2. Do you think it would sound better to buy another set of Heimdall 2 speaker cables, or go with a slightly cheaper option of buying the nordost reference jumpers? I won't be able to demo the jumper cable option.
