http://www.fmacoustics.com/set_misc.htmlQ: Why does FM ACOUSTICS not use detachable mains cables? A. The main reason is that the cable is an integral part of these products. By fixing it we can assure the quality of reproduction is optimized and no deterioration can occur. Also, with a detachable mains cable three additional contacts are added in the mains line. These are unnecessary and wherever possible contacts must be avoided as they are a weak link and it is always better to have as few contacts as possible. This is also the fact with the widely used "Euro" plugs which are not suitable at all for high currents. While their ratings suggest that they can handle high power, practical experience shows that the contacts of these plugs are not optimal and often there is quite a bit of "play" between the plug and the socket. Due to this, the actual area making contact is rather small, clearly too small for high current demands. As the contact is not perfect, micro-arcing makes these contacts loose their initially more or less reasonably smooth surface within a short time. Thereby additional resistance is added into the mains line, certainly not what is wanted in precision audio... The lower the impedance, the better - the fewer contacts in a product the better it will perform and the better will be reliability. Q: In your cables, why do you not use silver as conducting material? A: Just because silver is a bit more costly a raw material does not mean that it gives better performance.The usual reason quoted for using silver is that silver's conductivity is better. Correct, but the difference to copper is a mere 2%. Therefore, by adding 2% more copper in the cables the improved conductivity attributable to silver is effectively negated. By increasing the pure copper content up to the optimum, performance will surpass that of the best silver cable (incidentally, there is no speaker cable with a satisfactory square section made out of pure silver). Other characteristics (such as e.g. shore hardness, oxidation etc.) make silver definitely less desirable than copper. However, one must be aware that considerable quality differences exist between the different copper cables. It is very important what kind of copper is used, how it is purified, how it is drawn, how the strands are prepared, etc. These differences can be audible. Q: Why are older persons still able to hear music details even when their high frequency hearing is limited? A: Indeed, it is often claimed that older persons cannot "hear as well" as the younger. This may well be so in certain noisy environments and when simply checking the hearing with steady state sine waves. However, it has been proven that when music is used as a source signal, older people - even those whose hearing of high frequencies is limited according to the orthodox measurements - are often acute listeners. They can discern very well and are able to point out fine details and characteristics in the music despite having a hearing that is less extended in high frequencies. While at first baffling, these results can be explained: many older people have not abused their hearing by being exposed to the extreme sound levels presented by the "walkman"-type personal audio devices and many of today's discotheque and P.A. systems. Also, many older people have been subjected to unamplified or reasonably amplified live music pretty much all through their lives. This keeps the ears well trained and sharpens the acuity that comes with experience. A recent example proves the case in point: a senior person whose hearing was clearly limited to 11 kHz according to conventional medical checks turned out to be the one most sensitive of a group of thirty experienced listeners. In a number of piano recording he was the most astute in pointing out details like small pitch variations between adjacent strings, the non-perfect intonation of a certain piano register and faint resonances.
