I can bi-wiring my KEF R500. Of course the dealer told this will improve the sound. But is this true?
Good question PP, have biwired for years ever since getting into home cinema and always on the recommendation of dealers, but am ashamed to say I've never taken the time to try single wiring as an alternative and have read some views that single wiring improves 'cohesion'.
Anyone out there tried switching between the two and have any feedback?
Same question about bi-amping?

IME no, I've never noticed any appreciable difference after bi-wiring. Bi-amping is a better option and there are gains to be had going down this route.
If the bi-amping is done with an integrated amp and an avr i can imagine this would benefit av,but would it be so for hifi?

Let him either show you with a demo, or lend you the cable to try for youself.
IMO. You will gain more by spending the money on better cable. I also like to replace the links (with short pieces of your S/C).....but I don't how how this might work with the R Series.
It is also possible the gain you "may" hear from Bi-wiring is down to removing the links from the equation.
People who believe cables make no difference, will tell you not to waste your time or money....but imo it is worth checking for yourself.

I think in some cases bi wiring can make some subtle differences it just depend on the speakers being used. Just because a manufacturer provides four terminals it doesn't necessarily mean that the speakers will sound better if bi wired. I used to tri wire my speakers and I found a little gain in the overall presentation. On the other hand bi amping can make a huge difference. I bi amp my speakers which allows all of one amp to get a grip on the low end frequencies and the other to deliver the high frequencies. Much gain can be had from bi amping.
Enjoy the music!
Bi-amping is usually beneficial, but is very different from Bi-wiring.
Bi-amping is not normally done with AV, usually with stereo amps prob because it is easeir to get a power amp to match the stereo amp But it is possible, you have to get a power anmp that will match the gain of the power amp stage in the AV amp. This means finding out the gain of the AV amp, not somwthig usually mentioned in the specs, I had to ring up Onkyo service, helpful but it took them a few days to get me the info! Then used a Roksan Kandy power amp as you can trim the gain to match the AV amp. I then used the Roksan to power the bass drivers of the front channels (L and R) There are those who will say that using the AV for any music duties even pre-amp ones should be avoided but I thought it sounded good. As ever you have to set it up and try for yourself!!!
Think my AV amp supports biamping if not all the surround channels are used (which they're not currently). I'll dig out the manual later and see what it says.
Excuse my lack of knoledge(ignorance)but i have a question
If the avr(high freq)-integrated(low feq)are used,then i was to turn off the avr and reset the link on the speakers would the integrated send the signal as if single wired..as normal?
Split terminals on speakers are designed for Bi-amp, if you bi-wire you are adding possible variables (Resistance, Inductance, capacitance etc.) of the cable that was not envisaged by the designer, thus possibly affecting how the speaker operates. (If you’re using a 2 channel amp always single wire and keep the links in)
Bi-amp (4 channels into 2 speakers) has benefits as it isolates the upper and lower crossovers from each other thus reducing the possibility of interference between upper and lower.
A lot of AV amps allow you to use any unused channels for bi-amp, and if available (And your speakers have separate terminals) always use it in preference over single wire.
Forget Bi-wiring as while it may alter the sound, it will not be as the designer intended, thus producing an inaccurate sound.
Hope this helps
Bill,i was told by a very trusted retailer that bi amping with my avr(using the spare suround back ch)would make no difference,could you expand on this,out of interest?
Whereas I am somewhat sceptical about the benefits of Bi (Tri)-wiring, the Kef manual specifically shows how to do it, which they wouldn't do, if the designers felt it would be detrimental.

For you it's academic, as the benefits of using a good 2 channel amp are greater (imo).
It may depend on the particular amp and how expensive the speaker cable is, as to whether it's worth doing. With the AVR600, I felt there was possibly a small gain (clarity and control); though I can easily see why this Passive Bi-amping is controversial (I didn't spend much extra to do it).
It is nothing like as effective as Active Bi-amping (with Active Crossover).
So to get a worthwhile result a seperate power amp should be used to bi amp?(my oppologies for being a pain in the rear)
Hi-Fi is all about opinions, which often conflict.
.......and mine is that you need to take the AVR's Pre-amp out of the loop, for 2 channel, as it will be the weak link. You are likely to get an improvement, but maybe not a VFM one ie. compared to getting a stereo amp.
In your case, I think you have done the right thing, so I wouldn't worry.
