For a budget - True bi-wire or bi-wire?

Al - don't forget about crossover components. Woofer is most likely in series with inductor that has resistance in order of 0.08ohm limiting damping factor to about 100. Icepower class D amps have DF=4000 at low frequencies - an overkill.

Yes, good point Kijanki. Thanks!

Thanks for the detailed response. As I have learned, it is trial and error. That makes any review of amplifiers superfluous unless you have the same speakers as the reviewer!

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.

There are only two genuine wiring methods, true Single wiring and true Biwiring. Every other by-product of this is a pseudo configuration.
If a speaker is built for true biwiring, meaning separate crossovers for each pair of terminals, it will sound far superior in biwiring configuration. In such a situation even a decent set of two separate run wires (true biwiring) costing say about $500 in total would easily outperform a single wiring set costing $1000 or even more.

Whereas if your speaker is not built with true biwirng as part of the design, even though it might have multiple set of terminals, you would never benefit from biwiring, you are much better off buying a nice pair of single wiring set.
In fact it can sound worse with biwiring as well.

You need to ask your speaker manufacturer whether the speaker is designed for true biwiring. IF he suggests you biwire, you can be pretty much sure that he has done it internally.
