In my experience bi-wiring has more to do with the xover and whether the manufacurer intended the speaker to be bi-wired. A good example is Dunlavy speakers. John Dunlavy was not a believer in bi-wiring, however, after numerous requests from reviewers and dealers John installed a second set of binding posts to accommodate bi-wiring. I experimented with single wire and bi-wire on my SC-IVs with several types of wire and I always preferred the sound with single wire. On the other hand Vandersteen speakers sound better bi-wired, so it really depends on the design of the speaker.
For a budget - True bi-wire or bi-wire?
Simple question. I have a speaker with four binding posts and monoblocks with four binding posts(for each channel). If I have a given budget for cables (say $1000), am I better off buying two pairs of identical $500 cables and do a true bi-wire, or buy a $1000 single pair of a typical bi-wired cable (i.e. no separate cable runs, but a biwire that is simply split at the speaker end)?. This is not about any particular calbe I have in mind. It bold down to how does the improvement I get from more expensive cable compare to improvement trough true bi-wire
