I am definitely erring on the side of the 5B ST due mainly to cost. I have a second query which I need to sort out

I will be using a Meridian 568.2 processor and am going to use balanced interconnects. I have some fairly good (home made

) speaker cable and was going to get some fairly high quality interconnects around the 1 metre mark and have the speaker cable at 6 metres. I've never used balanced before so would it be better to get a lesser quality 5/6 metre interconnect and use shorter speaker cable?
