Speaker Break In Question - going from single wired to bi-wired

Ideally you should run 2 pairs of speaker cables to different amps (i.e. bi-amp).  AND use a monoblock for each driver with a short cable...

Dick Vandersteen does like bi-wiring and IIRC he has some explanations for it on the internet somewhere.

That does not mean it will work with all designs

" Ideally you should run 2 pairs of speaker cables to different amps (i.e. bi-amp).  AND use a monoblock for each driver with a short cable.."

Biamping like you are suggesting almost always fails. 90%+ chance you'll need to get an active xover, and they create as many problems as they fix. It makes more sense to do a vertical biamp with 2 identical stereo amps because you can get around all those problems. Actually, not long ago I was fooling with my system which has 2 Ayre V-5's amps in a vertical biamp. I connected them horizontal to see what it would sound like because its been a long time since I last tried it. It turned out to be a train wreck. It ruined the overall sound of my system.

I do believe bi-wiring is a voodoo thing ,it's better to invest on good jumpers or biamp with 2 identical stereo amps as @sfall suggested for a real sound improvement. 

Yes, I don't think anyone will claim that biwring is as good as biamping - the problem with multiple amps is cost.

sfall - no manf. would use an amp for every driver with a Xover between them - you would use DSP ahead of all amps to deal with this, as meridian has done since the 1990s - yes, expensive

Richard Vandersteen has always been clear that running two single wire sets of identical cables or at least cables of identical topology is the way to go with his speakers.  RV provides designs of such value that few customers have bawked at the extra expense. If you have the $ to bi-amp then have at it and congratulations.  If you mate those amps with quality wires you should be getting from the speakers that which they are capable of giving.
