By "true" I mean connecting 2 runs of separate cables instead of the usual bi-wired cable. Does it help?
How important is "true" bi-wiring to the 802d?

Here's an interesting read concerning an argument that there is a difference between a bi-wired speaker system and conventional wiring due to a difference in their cable power dissipation behaviours: http://www.audioholics.com/education...able-conundrum

hi,
for me a really bi wiring is not a cable with a 4 termination but 2 set of single speakers cables: more expemsive but is the true and give a really improvement at the speaker-sound.
of course buy a 2 set of single way of cables from a good level is more expensive but give a really bi-wiring sense.

using biwire with equal length would allow the treble and bass signal to travel on their own path and therefore less signal interaction. It may or may not sound different to you, but for me the sound is more open. Manufacturer have separated the crossover for treble mid and bass units for similar reason and it woud be logical to use biwiring if the speaker permits.- Bottom

Really? Is there any technical logic behind this distinction?
Kal sorry but a bi-wire cable is with a 2 spades/bananas at the ampli side and at the other side (speakers) you have 4 end.
each cables is double : at the start in a single bananas and at the end you have the 4 cables for your speaker:
if do you have 2 single way cables (2 set) you have on the paper the same like a bi wire cable but the quality from a "double cabling" is sure better (noise, clean frequnecy,.) vs. a bi-wire cable.
if do you go in a hig end store a lot of setup have this 2 set cables for the bi-wire and not a single cable bi-wire/splitted from 2 to 4 ending.
do you think that the single way cable with a jumper cant be at the level from a cable bi wire?

In essence the biwiring still happens at the speaker even when single wired. The only difference with biwiring is that this common point is moved 6 ft back towards the amp (assuming 6 ft speaker leads).
Now on cheaper speakers that use a goldplated bar to jump the LF/HF terminals I am a big supporter of replacing this with speaker cable..Main System:

Your amp is just jumpered on the inside which makes biwiring easier then connecting two leads to one set of posts. It is still the same electrically.

And I though I had something especial. :-).
If you see the picture in detail, there are two kinds of connections for left and right channels; the choices are current and voltage. the rest of the channels uses voltage according to the manual.
there is another note on the manual that says:
NOTE: The Current Source output is a Voltage Source modified to yield
an impedance of one ohm. This corresponds ap prox i mately to a vacuum
tube amplifi er's output im ped ance and constitutes the dominant factor in the soundstage delivery of classic vacuum tube power amplifiers."
As I read all these It made me belive that in fact bi-wiring was different on this particular amp.
I happend to use all sources and I didn't like the sound. I ended up connecting using one single ended wire at the amp and bi-wire at the speaker end and suing the voltage side of the source.- Bottom
Comment

Sorry olilugo,
I didn't see that description on photo you showed. What you have is Bob Carvers "Down Tracking" technology. On this amp you can use your amp with a very low output impedance (voltage source), or a higher output impedance which is more similar to a tube amp (current source). You can also use both.
Although you would do this in a bi-wire configuration, this is not really true bi-wiring. It is actually closer to bi-amp since you use a difference amp configuration for the HF then for the LF. Sounds interesting...Main System:

I have always been intrigued by expensive cables, mainly for the simple reason they look cool but deep down I was skeptical of the difference they could make. It wasn't until this past December where I was finally offered an opportunity to use a pair of relatively expensive cables, a 7 foot pair of Kimber Monacle XL and frankly I was shocked at what I heard, yes heard.
There was absolutely no mistake, the highs opened up to such a degree I may as well have been using different speakers, it was like I had been listening to my speakers with a blanket draped over them. I couldn't hear any real discernable difference in the lows but the mids were noticeable tighter. My speakers, Paradigm Reference Studio 100v2, I have had since the summer of 2002, my amp is a Bryston 4BSST which I have had since January 2004, my surround sound processor is a Lexicon MC-12B which I have had since January 2004, and my speaker cables are Ixos 6006 (I think) which I purchased with my Paradigms along with Kimber PBJ balanced cables for connection between the SSP and amp. Since I have lived with these components for years any change to my system which can yield a different sound I will immediately pick up on and I can say with absolutely certantity, if I was blind folded and someone was randomly swaping between my Ixos and the Kimbers I could tell the difference. Like I said, I was shocked at the difference a bit of copper can make.
Now I won't go as far as to say expensive cables make a system sound better, what I will say is different cables do in fact produce audible differences.
Based on the Kimber test I immediately wanted the Kimbers for my upcoming 802Di's and just purchased HTM2Di however in comparing the price of 3 12'-15' Monacle XL's it's only a bit more to get a pair of 805Di's, so with reason and not passion taking over this is what I am ultimately going to do as I want to replace all of my Paradigms with B&Ws. I will indeed get the Kimber's down the road but only after I get the speakers I want.
So to the topic of bi-wiring, I can't comment on that because I have never bi-wired speakers but my advice would be, if it is a cable upgrade you are looking at doing I would focus of getting a very good cable first and if a bi-wire option is available then perhaps consider it if it's not a substantial upgrade to the cost. I would wager you would get/hear more by going to a solid non-bi-wire cable then you would get from going with that excellent cable to it's bi-wire configuration.B&W 800 Diamonds (L/R), HTM2 Diamond (C), 802 Diamonds (SL/SR), Paradigm Signature Sub 25 (LFE), Reference Servo 15a x 2 (Stereo subs), Lexicon MC-12Bv5EQ SSP, Bryston 28B-SST2x 2, 7B-SST2x2, 4B-SST C Series, BDP-2, Oppo UDP-205, Pioneer Elite Kuro PRO-150FD, Furman SPR-20i, IT-Reference, Eastlink Maestro PVR, Xbox One & 360, PS3, Siltech Golden Ridge II, Ruby Hill IIx2, 330ix2, Kimber Kable PK10 Gold, Tonic, PBJ, Cadence, HD19e, HD19, OPT-1, HDSW 4x1, Ixos 6003, Harmony 1000- Bottom

While those cables on the Magico looks amazing (and probably sound amazing too), it looks the the girth is only padded since the actual cable heading towards the jacks are 10 gauge or 8 gauge. So really, using two high gauge cable would do (metallurgical properties and other technical geewizery notwithstanding).

What about optical cables? I always enjoy a laugh at the hifi shop when i ask them if its worth upgrading my optical cables. If I could be bothered, I would make my own cables from thick, pure silver wire and PTFE tube. I use VDH cables as that is what B&W used and Meridian. I have balanced long interconnects and short biwired speaker cables terminated with WBT connectors as thats what the speakers have. Sounds great!- Bottom

Something to consider when bi-wiring. One reason for bi-wiring is to eliminate the cheapie jumper sometimes supplied with the speakers. If the amp being used has two sets of binding posts, only one of the sets is internally wired. The other one is connected with a jumper. I make it a point to used the wired binding posts for the upper end and the jumped binding posts for the bass. By doing this we somewhat eliminate the jumper from the amp which is why we bi-wire to begin with. This came to me years ago when I had the top off one of my Krell amplifiers and noticed the flat metal jumpers which appeared to be aluminum.- Bottom

Funny how cable/wiring discussions generate so much aggression/sarcasm and firm positions!!!
I have a simple question/poll to everybody who posted in this thread.
Regardless of money considerations, worth/not worth, better/worse sound, presumed/assumed/real technical considerations, I'd like everybody to answer YES/NO to the following question: HAVE YOU EVER HEARD A DIFFERENCE IN SOUND GENERATED BY SIGNAL/SPEAKER/POWER CABLES?
(for who will answer "NO", poor guys, this means that either your audio system is not revelatory enough to highlight the differences, or your ears are not good enough to hear them ops: )
Jokes apart, I could hear differences, and not small, on my system, on some other friend's system, and my friends can spot the differences too (even people not in the hobby), and if the difference is big enough, you can spot it even in blind tests, even my GF does spot the differences (and I mention her as she loves music, has a good ear, goes to live events, but cares NOTHING about the gear). So how is it possible that some people is so firm in saying "No way, it's not possible?"
After all, we speak about "nuances" provided by speakers, electronics, we speak about the room, and JUST CABLES, cannot deliver differences?
Just curious why these poor cables are not allowed to contribute to the sound. Then why the Esoteric would, in the upgrade from X01 to X01LTD, change the internal wiring to higher grade copper?
@Kal: I respect you as one of the world-known reviewers, and I read with interest Stereophile, so for me it's a bit strange that your approach is not open-minded on this topic ("Nah"). After all, Stereophile reviewed my electronics table concluding the difference can be heard (http://forum.stereophile.com/standsr...ite/index.html), and it was key in making me decide to fork the cash. So again, why are cables not allowed to make a difference?2ch Setup: Esoteric SA-50, Linn Sondek LP-12 with Lingo and Ittok, Benz Ace SL, Gryphon Diablo, B&W 802D, Kubala-Sosna Emotion XLR and Speaker, Purist Audio Dominus power cords with Oyaide C/P-004/046, Finite-Elemente Pagode Master Reference, Cerapuc, Cerabase, Bybees
