bi wire

我覺得玩bi-wire喇叭線就係想高低頻分開線走，可讓聲音分離度提升和分析力加強，但現在你再加 jumper，不是 ...

我玩緊bi wire+jumper。加咗jumper之後，聲音密度提高咗約四份一，音與音之間的連貫更好，轉彎後更順暢，細緻度也有提高，係音質上的提升，並非音色上改變。

This is because you are wrong at the very first step: Not using two same speaker cables.

Your case is you MUST use jumpers becuase two difference speaker cable for bi-wire will cause very high crosstalk distortions, the jumpers short them together as one speaker cable so the crosstalk distortions gone, you are not improve, you are just cure the distortions by luck.

U mean need use same band or same model?

咁行single wire再用jumper，但SC與jumper又唔一樣brand或model，咁又有冇事呢？

Same brand same model.

Actually even two exactly same speaker cables, or some 4 core bi-wire design single cable, there will still have crosstalk distortions, however it is not as high as two difference cables, therefore low enough to ignore.

Bi-wire is a save cost method originally from bi-amp/electronic cross over, but due to speaker cables is totally passive, plus the negative return path is acutally same as short together, no individual drive or isolate by individual amplifier/electronically, once two cables have difference electrical charaters, crosstalk distortion happen from the negative return path.

Many basic rules already being mislead by years of commercial fights, all is just about make sales, this is also because why some loudspeakers brand such as Dynaudio, they even not allow bi-wire connections, because they try to aviod such wrong "rules" make their products performance being worse.

冇事, first the jumpers are short enough to get rid of crosstalk distortion happen, 2nd the jumpers are only replace the stock suks metal bridges comes from loudspeakers, which even you are not pay for a set of brand name jumpers, but simply cut some good conductors, you still need to get rid of thoes bridges, since those bridges are parts of the circuit, the whole loudspeakers not working without them, but the materials are even worse then thoes copper trace on a PCB.

by the way ckw3031 hing, you can do a test.

Connecting your two speakers cables togehter at the low terminals, same as short them together as a big speaker cables, connect the jumpers as usual from low to high, compare the sound with your currrent connection, pay attention to any changes of low level details and extrem high dynamic, see which connections sounds better?
