Why use speaker cable at all with monoblocks?

I imagine that the type of audiophile who would employ mono power amplifiers would not like this integrated amp/cable approach. If someone was really trying to optimize their system, then what are the chances that the amp manufacturer would select the exact cable that makes a specific system gel? Odds are that a typical mono amp user is willing to devote more money to their choice of cable than the amp manufacturer.

A slightly different situation would be for the speaker manufacturer to include cable at the speaker end. The speaker maker could tailor the cable characteristics to the specifics of their crossover design. Still, most audiophile would probably like to chose their own.

Pro audio has used biamping and "active" monitors for at least 35 years. Their goal is to minimize signal path, reduce the number of connectors and reduce number of separate components. In its pursuit to perfect each individual component, each function in the signal path, high end audio seems to take the opposite approach: multiply number of individual components in order to perfect each one, and thereby multiply the number of connectors, lengthen the signal path, and highlight, naturally enough, the importance of good wire and connectors.

Also, as has been pointed out, the pro audio user mostly wants to settle his component set-up and get on with the job; the audiophile frequently wants to be able to change components on an ongoing basis.

I plan one day to strap four Meitner monoblocs, fed from an electronic crossover, to the back of my Tannoy DMT 15s and see how they sound with six inches of cable. Even then, though, I don't think I'd hardwire them--can't see changing the speakers, but who knows what amplification might turn up?

Who was it, Yves Bernard Andre who went on and on about why 1.5 meters is the minimum cable length required to mate an amp with a transducer? Forget why. Not even sure YBA sells/makes cables, either.
Pro monitors do it for simplicity and compactness, not to optimize voicing. Hell, most of them have separate mid and tweeter level controls for room/taste-matching. You think Genelec, etc. do this to remove cable-voicing? C'mon....

You have to hook up the speaker to the amp with something, a piece of wire or metal strap. If you save on the speaker wire you will need to use a longer interconnect cable to get from the preamp or your source cd/tuner/phono. Want to run multiple long leads to your amp. Your choice.
