Wokay...I've just tested the coiled and straight cables by plugging them straight into the amp. Test results show that the coiled cable cuts down the highs a little, hence, more noticeable lows but somewhat, more 'nasal' tone. I have a feeling that it's due to the additional length of the coiled cable (think about it, if you uncoil the cable, it's so much longer...hence the 'low capacity' print on the cable).
