WOULD I BENEFIT ANYHTING IF I BI WIRE MY KHORNS???

Been wanting to try this myself. I use a Luxman int amp as a preamp with a Cayin TA 30 tube amp. My La Scalas are 2004 with both HF and LF wire connections. Is it possible to use the tube amp for the HF and use the Luxman's amp section, remember it's a int amp, for the bass or would I have to have a separte amp for the bass? Also how would I run 2 preouts to the amps from my Luxman preamp if it only has one preout? I also have a 85 Luxman preamp with 2 preouts on it but my 2004 Luxman int amp sounds better.

I have 2 Monarchy Audio SM 70 Pros 80 watt monoblocks that I'm going to sell but I can try this before I sell them.

I saw you have a Marantz CDR-630 Pro CD Recorder how do you like it? When I make cds on my computer they do not sound very good on my 2 channel system. Have you done a A/B comparision between the original cd and the copy? How much is the Marantz?

Bi-Wiring is a very dubious proposition.

There may be some effect at ultrasonic frequencies (but not at audio frequencies). Unfortunately, it is the effects at the ultrasonic frequencies that folks refer to when trying to bolster their arguments.

The fact that the stereo salesman wants to sell you a bi-wire cable for $120 says it all.

Seriously, speaker wire should not cost more than 50cents/foot. If you must spend more money on your stereo, use the money to re-arrange your room, add (or remove) carpets, pads, and drapes. Those manipulations will have a much more profound impact on the sound.

Good luck,

-Tom

My good friend, Noel Lee, says bi-wiring will improve your sound quite a bit.

Hmmm. No vested interests here! 2.gif

J.4Knee is right!

Save your money.

Or spend it and your time however you like!11.gif

Personally I would rather spend my money on $1500/meter interconnects and exotic current source power cords. Hey, and all I can say is my aluminum foil lined hat sure improves the imaging!

Axiom Audio:

If you look at the amplifier as a current source, then for amplifiers and receivers that are capable of supplying lots of current into LOW IMPEDANCES, biwiring could offer theoretical advantages, particularly to loudspeakers that are linear and smooth, like the Axiom M80ti and M60ti, by eliminating potential INTERMODULATION DISTORTION between the low- and high-frequency portions of the audio signal. Using biwiring, this distortion would not occur because the low-frequency part of the speaker crossover would draw the current it needs for the woofers (and they need lots of current) through one speaker cable, while the midrange tweeter section would draw less current (it doesn't need as much) through its own speaker cable. This could prevent intermodulation distortion that may occur using one big fire hose or single speaker cable.

(Using two cables per speaker will also lower total resistance to the audio signaland that is well and good, although a single run of 12-gauge cable to each speaker WILL KEEP RESISTANCE TO AN INSIGNIFICANT LEVEL, WELL BELOW 0.3 OHMS.)

and...

The above results imply that bi-wiring may alter the frequency response and that, when using a very simple speaker system with an impedance of around 8 Ohms, this variation may be of the order of 01 dB when using cables whose series resistance is around 01 Ohms. Thus, in principle, it seems possible that bi-wiring may alter the systems frequency response. The details of any change will then depend upon the series impedance of the cables, and the impedance properties of the loudspeaker.

Two things should be kept in mind, however:

In general many loudspeaker cables will have a series resistance value well below 01 Ohms. Indeed, a low value is advisable to avoid other types of interaction with the loudspeaker input impedance. Thus in practice the actual variations may well be much smaller than those plotted in Figure 9. As a result, it is debatable if any variations in practice will normally be large enough to be audible or to be regarded as being of any real consequence. Moving your head a few centimetres when listening may have a larger effect in many rooms.

The model used here is a very simple one. Hence we should really only consider these results as implying that effects can occur in principle. The plots should not be taken to indicate what will actually happen with a more complex and realistic system.

It is also worth bearing in mind that the detailed analysis carried out here assume coherent addition of the HF and LF signals. This will be correct for a a listener at a fixed point when considering direct radiation from the loudspeaker system. The situation when the diffuse soundfield of the loudspeaker is taken into account may be more complex. However for this analysis we are simply interested in an in principle answer. Hence we can see this as another complication which means the actual performance in reality may well differ from the above results, but that a small change due to bi-wiring remains possible.

Thus we can conclude that there may be a small effect due to bi-wiring, but the above tends to imply it may normally be so small as to have little significance. In order to say more, a detailed model of specific realistic systems, and/or some precise measurements, would be required. These might reveal a more noticeable effect in some cases, but the above taken by itself implies the effects will usually be very small if low series impedance cables are used. It is also perhaps worth bearing in mind that - even in a case where any change in frequency response is large enough to be audible - this does not establish that the bi-wired arrangement will inevitably then be better than using a single cable. That would depend upon the circumstances of use, and the preferences of the listener.
