Listen to goldengreek51 . He is correct .Analysis Plus' Big Silver Oval speaker cables deliver what you desire . Your speakers are rated -7dB @ 35Hz ,so you will not get more power out of them , but their full impulse response will be revealed for the first time .
Read AP's tech info and understand why NASA chose this cable for it's ability to pass a high current square wave . Music is all about dynamic impulse , the energy in the sound . Their patented geometry is Why they are better . You are after a more dynamic bass and this will do it .
Their Silver Oval Two is lower priced and was good enough for me and might be for you , too . They are better than the 12 gauge Anticables I used before to my Spatial Audio M3 Turbo S's . Minus 3 dB @ 35 Hz .
Their largest vendor sells below retail on eBay , which is where I bought mine . Custom lengths can be done also . They make Pro Audio cables of all kinds as well .
