......... I'd vote against bare wire due to questionable connections (reliable electrical contact and strength).
That may be true in theory, but in my case, not in reality.
For speaker cables I use Morrow Audio. Recently, I jumped down
three models and got
better sound by simply eliminating connectors on the speaker end (amp end has connectors). I went from SP5 w / BFA bananas to SP2 w/ bare wire.
Hard to imagine, but less is more, I guess.
Based on this, I'd also like to eliminate connectors on amp end, but I run two sets of cables to each sprkr and I'm not able to securely attach two bare ends to each amp output post.
I've no idea if what I'm hearing is brand specific, but I recommend that Morrow users try this. To my ear, the effect is not subtle. While I don't deny the effects of cable changes - I hear them for myself -- I tend to be a bit of a doubter by nature and not big on subtle tweaks, nor prone to be swayed by psycho-acoustical effects.
PS: I now use double runs SP4, bare wire at speaker ends. Nice improvement over bare wire SP2.
