Interconnect length

No, going from a 1 meter interconnect to .5 meter will not provide any sonic benefit all things being equal.

I couldn't resist to respond, and I can't confirm this, but I understand that interconnect diameter is more important than length;)

said above:> "Hardly any current on the interconnects. 1/2m, 1m, 3m... no difference or none to speak of. Speaker cables, that's another story.."

Not sure exactly what that means but it seems to infer that
you do not have to worry about interconnect length because there is so little current. Actually that is precisely why you should be concerned in many instances. Long interconnects can present a lot of capacitance to the signal source which is difficult for them to drive because of the limited current. Power amps (pushing speaker cables) chave higher current capability and it is far easier for them to drive the added capacitance. In addition, you will generally pick up more noise in ICs than speaker cables.

If vinyl isn't involved a few inches probably won't matter.

I remain,

You always can subtract but can never add... if you should reposition in the future, that extra 1/2 meter can save you the trouble of buying the same thing twice.

No difference in sound but in any other application 1/2 meter is really short, I've got 2 sets of 1/2 meter and they worked great in my former configuation but are too short now, money saved now will cost you more later...
