Shorter speaker runs or shorter IC Runs...Which is the better set up and why?


Hello all!

So I am setting up 2 Bryston 28b Mono Amps and I would like opinions on which is a better way to do it? Should I place the amps close to the speakers with longer XLRs/shorter speaker wire OR longer speaker wire with a shorter XLRs and why? I think I know what conventional wisdom says but I am looking for the best option.

Thanks in advance!

Ralph, can you explain why on Earth some designers and makers of consumer electronics go to the trouble and expensive of providing balanced connections (if not circuits), and then don't do it "correctly", to conform to the AES standard? To do that defeats the whole purpose of balanced! It costs no more to do it right, either. Just connect the correct wires to the correct XLR pins. Duh.
My guess is that they don't know about the standard, don't care, don't want to the expense and stigma of an output transformer or some combination thereof.


The only other way to really do it right (so the output really does ignore ground) is the way we do it, which is patented.
Decades of live sound work doesn't presume you've heard a good cable.
The whole point of going balanced is to get off of the exotic cable merry go round.
Imagine a technology where a $100 cable can sound as good as a cable that's $1000/foot. That's the balanced line system. So in effect, if one has been doing decades of live sound, the cables have worked as well as the best out there for the simple reason that the balanced line system works that way.
One caveat: pro audio gear supports the balanced line standard. Most high end audio stuff does not. In order for the cable to not have a sonic signature of its own, the equipment must support the standard. In a nutshell, here it is:
1) pin 1 is ground, pin 2 is non-inverting, pin 3 is inverting2) the system is low impedance; the source must haveĀ  the ability to drive 1000-2000 ohms without worries3) the system ignores ground (pin 1); no signal currents are passed through the pin 1 connection (shield of the cable). This is where most high end audio stuff misses the mark.4) the impedance to ground from either pin 2 or pin 3 is the same.
5) the signal travels within a twisted pair usually within a shield.
When I went to long XLR connections and short speaker cable runs decades ago the improvement in clarity was immediately obvious! Better bass impact too- the improvement was across the board.

If your gear supports the balanced standard (AES48) then the length and cost of the interconnects is almost immaterial. OTOH speaker cables have a big effect and the shorter you can make them the better.
