Bi Wire vs Speaker Jumpers

there are many threads on this subject

Based on my experience with bi-wiring on more than a dozen speakers, it makes a difference with 3-way speakers and large woofers.
Unnecessary with 2-ways. Also no need to spend a fortune on nicely worded pseudo-science, large gauge ropes of pure copper is all you need, especially with low impedance speakers (i.e. bass drivers).

I have 802d3

i do single wire but with biwire ends.  I’d rather use the same cable for both bindings post pairs rather than a dissimilar jumper wire

I have a Sansui B2102 MosVintage amplifier and a T+A  TB160 speakers. I tried to remove the jumpers and use a  Bi-wiring. It is impossible to listen .. excessive thread. Almost scream. The next experiment will be Bi-amping. Just for the experiment. Chord Mojo has two LineOut. The second amplifier is Ouad 405.

Bi-Wire = Buy Wire
