There's a huge improvement by double wiring; And even more if you double the low cable (because the boomer need much power, and when you double, you lower the cable's resistivity), this result in an huge improvment on all criterias: image (soundstage), dynamic, low and HIGH. When you bi-wire, you relieve your amp by lowering cable's resistivity. In hifi, you have many theories. But sometimes theories don't match with the practice. A goodtube amp has higher distorsions levels than a transistor amp. But when you listen, it's night and day: the transistor amp will make "rape with cheese" in the highs, whereas the good tube amp will give you shivers on voices, violins, trumpets, in one word: music! So what does it means? It means that it is'nt the good criteria for judging musicality. It's the same with the bi-wire or bi-amp question: some will tell you that it creates problems with filters and other things... But when you do, it's better: more musical. And that what's important. |

There is definitely an audible different even for my humble system when I biwire. Surely the amp itself splits up the signal? |

I've always had my doubts about the benefits of bi-wiring. Here's an article on the subject: http://www.eastwoodhifi.com.au/tweak.htm The first part reads: Bi-Wiring, this'll upset any audiophiles who slipped through my front page warning! For general home use, bi-wiring speakers offers absolutely no benefit whatsoever except for doubling the thickness of the speaker wire (which is why most people can hear an improvement). Those little electrons don't magically split into various frequencies and follow the path to the correct speaker (tweeter, woofer or whatever) so don't waste your time and money. |

Erratum: I wanted to say "tubes are better in the HIGH than transistor", and not the contrary.
To the sad fellow above: I wouldn't want to be in your place. It's hard for your ego that a "teenage" learn you life. |

I say tubes for high because it's obvious tubes easily beat transistor in the bass freq but the low are still a little "round" with tube.
So, it's a way to combine the advantages of each technology. You don't know that, after 25 years in Hifi? |

Oliver i said that using your tube power amp is a bad idea blasting rock music through due to the threat of over driving your tubes & putting excessive strain on your output transformers.You said near enough i was talking bollox. But above you've just contradicted yourself saying tube for high end & transistor for low end power.You must use transistor on low end for loud rock music,agreeable regarding tubes for high end but christ Oliver make your mind up |

yes, for one time, i agree with him
I'm a bi-wiring adept (and even to double the low-freq! remember!) and bi-amp with tubes in the high and transistor in the low is the royal way! |

Yes the additional wiring is worth it.Bi-wiring you actually power each section of the cross over.More control & x-over interaction between the driver units is down to minimum...This is really only an evident upgrade if you have excellent quality equipment.Remember bi-wiring & bi-amping are different...

This bi-wiring really brings up the sound? Is the double wiring (and therefore double the cost) really worth it?I have B & W A6304 speakers that would allow such thing and good cables . I know that cables do make differences as I saw recently when I got rid of those stupid white and red RCA connector supplied with my NAD amplifier. I chose some uni-directional silver wires with Gold contact between my CD deck and the amplifier and what a difference this made! |

Yes you can use a seperate power amp per set of units,this is called Bi-Amping.Even better results is to use mono block power amps per each unit per each channel.But you must have a split cross over,most serious speakers these days have Bi -Wire facilities.Apart from the obvious lack of Cross over interaction between unit frequencies you also gain with mono block power,the fact that the amp has its own dedicated power supply,same kindda thing your trying to gain by bi-amping...
What is the difference between bi-wiring and bi-amping?
Oliver mentions using Valve power for the high frequency & Transistor for lower end.This has it's good points but ideally you need the same output from both variant or you could end up with a serious mismatch level.Ideally if your gonna do this you want a gain control for the Valve power amps to tailor the output,but as it goes in serious hi-fi you trying to scrap as many sound barrier hurdles in the chain as you can ie:volume/tone controls,switches etc which all add resistance to the chain. |

Yes, you can use one amp par channel, for a better "image" and when you bi-amp (tube amp for high freq and transistor amp in the low),that can make a total of 4 amps! And you can bi-cable moreover. I have bicable and double the low freq cables (which makes 3 cables per speakers, 150€ the meter of cable) i know a very big audiophile who has transparent opus speakers cables, which costs 120.000€ (150.000dollars) cause he has 4 pieces of transparent opus cables (30.000€ per piece of cable) he heas one of the best system in the world! (that's him who has the best Mark Levinson cd player in the world : 45.000 dollars with cables) |

So I was avant-garded without knowing it... In my case it wasn't frivolity, but lack of resources!

I think I read somewhere that some audiophiles today use seperate amps for each speaker, or maybe it's a different amp for each of the 2 inputs on some speakers. My speakers have 2 inputs (bi-wiring for treble and bass), but I'm not so frivolous as to have 2 amps .

Reading the thread about were you listen to your first prog purchase, I remembered that when I was 17, I had two amplifiers. Each one of them had a channell burnt, so I plugged the right output of my turntable and the right input of my cassette corder to the one with right channell ok, same thing with the left channell, and recorded very hilarious tapes (for some reason, the sound where "faster" in one of the amplifiers, so the tapes have a delay between right and left channell).
