Must Silverlines Boleros,specifically be biwired?

Silverline recommends biwiring on their site for
Boleros and other speaker models.
Is this really important? Thanks.
My Silverline Sonata III are also supposed to be bi-wired. I tried them bi-wired, and with single runs with matching jumper cables.

I prefer the single wires. It sounds more cohesive to me, but the differences between the two aren't large.
Tvad, Thank for the post. Any thoughts on the Sonata vs. the Bolero?
Thanks again.
I've never heard the Boleros, but they are more expensive so they must be better.

Don't you think?

Absolutely! Well said. :->
If you look at the Silverline site, it refers to a 6moons review, by someone who went from Sonata's to Bolero's. He said they were different rather than better. From memory, the Boleros were detailed, but smoother than the Sonatas, which seemed to have more bite. Really a question of personal choice and system matching
