I'm new to this Hi-Fi malarky so I'm not sure how to go about this the best way. Can I use the speaker A connections to wire the left and right treble speakers and the speaker B connections to wire the left and right bass speakers treating the different size speaker cones in their respective cabinets as though they were a second set of speakers? In short, treating the speaker A connections as an HF channel and speaker B connections as a LF channel? Is this how it’s done?

This seems to make more sense to me than having one + at the amp end splitting into two at the speaker end (likewise for-) - and running them all from the speaker A connection - this is what it says in my speaker manual - but I don't see how the bass and treble signals separate out this way!

The manual has clear instructions on Bi-amping but on Bi-wiring it's the same as the speaker manual.The speakers are Mordaunt-Short 914s, cable is QED original and interconnect is Cambridge Audio Azur Reference.

They don't - both the HF and LF sections of the speakers are fed with the same full-range signals in biwiring, so it makes no odds whether you use both the Speaker A and Speaker B terminals, or just run the two sets of cables from the same terminals.

Thanks for the help - seems a bit counter intuitive - but, hell, that's why I thought I'd ask someone who knew what they were talking about! The review I read from this mag said that the speakers would sound at their best bi-wired. But if the signals are not separate, how come they should sound better? Or is this (a) too complicated to answer or (b) just a load of old baloney!

Thanks again, Andrew.

Hi,

Following on from the previous posts around bi-wiring - can you help?

I have just bought the Azur 640A v2 and 640c v2 which came with free cambridge audio S30 speakers, Cambridge audio Atlantic interconnects and gale symphony 100 speaker cable.

Whilst tone and accoustics sounded clear (playing Radiohead's Ok computer & U2's remastered Joshua Tree, I felt that bass was a little bit "missing" in places.

I have read that bi-wiring will improve the sound - can you suggest bi-wire speaker cable (or other), better interconnects or even better speakers that may give me better listening pleasure?

Thanks in advance,

A Hifi Novice

I would audition a pair of Monitor Audio BR2s, there should be a noticeable improvement in bass. At this price level, changing speakers is going to have a far greater difference than almost any other upgrade...

Bi-wiring sometimes helps, sometimes it doesn't. My Eltax's don't benefit at all, whilst there is a subtle but worthwhile difference on my RS6's. The only advice I can give is to try (Gale 100 cable isn't particularly expensive, so give it a go...) and see what your ears tell you.

BTW, I'm also using CA interconnects, and find they do the job fine.

My speaker manual says bi-wiring improves the speakers. The manual is worded almost exactly the same as my old MA B2 manual, probably because both were written by the same person. I am not sure of the difference between single wiring and linking the two pairs of posts with the links supplied or cable jumpers, and connecting to the four posts separately with bi-wire cable or two single runs (the latter I have at present), usually with banana plugs for convenience. Someone did tell me (Richer Sounds I think) amps with speakers A and B are for running two pairs of speakers, not for connecting one pair because it would 'confuse' the speakers. Something about altering the impedance.

Well, plenty of folks reckon they can hear a difference but I think it's answer b)
