    This doesn't hold for some older Naim amplification, but logical though it may sound for other kit, I wonder if this would be applicable to all amplifier-speaker combinations (apart from said C/B and Olive Naim).

    I've always had my amplification with my other kit at the other end of my rooms where the speakers are, partly because I like it all within reach and partly because there's generally no spare and safe space to put the amplifier(s) near the speakers.

    I have 11 metre runs under the concrete floor but simply I/Cs to connect pre & powers. If I were to run 11 m of I/C to the (ESL) speaker based amps, it would cost a small fortune to equal the quality of the I/C to that of the (NAC A5) speaker leads. As my ESLs are energised, I can't quite get my head around any potential gains or losses which may accrue. It would certainly be a p.i.t.a. to slide a flexible I/C through two lengths of trunking (2 for the r/h speaker).

    Swings and roundabouts, maybe, or definite potential gains? My brain hurts.

    Will always be amps and speakers that don't fit in. Naim stuff is an example I guess.
    11 metres is a long way for interconnects. I doubt in your case it would produce anything better.

    I use a pure silver cable between my pre and monos. Funnily enough, they are sat very close together to each other.

    I use two monoblock amplifiers, each located directly behind the respective speaker, so the speaker cables are less than a metre long. The amplifiers have a balanced input and are fed by 15m lengths of balanced-line cable running under the floor back to the preamp, which itself has a true dual differential output and is of dual-mono construction using separate power supplies for each channel.

    Speaker cables need to have a low resistance so as to maintain a high damping factor, to absorb the back emf generated by the speaker. They also need to, at times, carry a heavy current - so ideally short thick cables are required. However with most electrostatic speakers the diaphragm has a very low mass, so there is less mass to dampen. In general, regardless of speaker type, a true damping factor (that is, taking the speaker cable loop resistance into account) of 40 - 50 is quite sufficient.

    To be honest, I don't think there has been much improvement over the previous arrangement using short interconnects and long speaker cables, but I do use electrostatic speakers.

    Yup, electro s won't matter so much but it's neater. Your fine with 15m as your also using balanced gear. I was going to move mine and try a 10m run of rca's but tbh I can't be bothered as it's sounding rather good as is

    So did I, and may do again. The difference between Artisan Audio (?) 8 core silver I/C and Chord Indigo (or Signature) is marked, with the silver bringing out the crispness/detail. Swings and roundabouts, though, as the copper I/Cs are more rounded in a musical sense. Should try my T.Q. Black Diamond, as Heaven knows what they're made of. I find experimenting, even at this basic level, tedious nowadays as it gets in the way of listening, so I usually reserve 'tweaking' until I have a bake-off and collate opinions.

    That's definitely grounds for complaint !
