Hello,
The good old snake oil questions/concerns...bi-wiring and the like.
The only reason I am bi-wiring my QWTs is because my cables are biwired with the exsiting speakers I have. They can be either biwired and biamped, one or the other not both.
I have honestly noticed ANY real sonic differences with bi-wring or bi-amping with these speakers.
I could have left one set of jacks just lying on the floor, but for the minimal cost I will have all four of the connectors attached to each speaker...
So have I had a good experience with bi-wiring, the answer is yes, but probably not any better than without bi-wiring!!
I would be happy either way, but the cabling costs for biwring will be more!!!
Bi-amping makes things even more expensive, and realistically unless all the part of your system, room and electronics are really, really top notch I honestly think your just throwing your $$$ down a hole.
Same thing for speaker wire, I used to take the $1000 6 foot lengths of speaker cable home to 'audition' and think I could hear the difference....now its 12 gauge wire from monoprice.com and some good soldered connectors on the ends!!
I would not want to rain on any ones parade that thinks these things make things better...but I want to see the oscillograph traces or real hard data to show me what the improvements really are...then I might partake depending on the cost trade-offs.
Usually when you read about how well bi-wiring or bi-amping or high dollar cables improve things you hear words like " better highs, lower lows, more transparent, yadda, yadda, yadda...Its never like the response curve at 3.5Khz is 1.5 db down which means.....
Its a great marketing area and its employing many people and there is definitely differences in cables, conductors, conductivity, terminations etc...but does this objectively relate to how spound is reproduced by your speakers??? Things like skin effect and hysteris are real things in physics and are related to cables, wiring, transmisson lines etc but do they really matter to our useage and to what degree???
The only one of these that I think "could' make a noticeable difference would be bi-amping, dependent on several things....speaker effieciecy, crossover design, impedance, amplifier dynamic range etc...but if you have a really capable amplifier that has 'very good' headroom, dynamic range....the real difference between bi-amp and not may not be 'worth' the cost, but it sure will impress the heck out of the novice....and its less money to loose in the stock market!!1
.....after all even i like all those glowing lights and leds!!
The only thing with the wiring is make sure the gauge is large enough to carry the signal over distances...
Ok enough ranting here..its a great discussion that been discussed soooooo many times before...
Show me the objective results, and you can make me a believer..
