"I didnot use their power cords I used the Eclipse 8Loudspeaker cable
which is very well balanced ,I thought the reviews on them were very accurate
I tried the interconnects , my Yamaha 2100 mosfet integrated sounds very respectable and very dynamic I wanted to give its perspective mores Row 8 then say a row 4 ,perspective ,theCardas clear reflection interconnect ,a perfect balance both cables complemented each other the latestwire world Eclipse 8
now a awg9 cable using the worlds best 48 individual OCC- 7-9s Copper
their top Opto meometry and obsilix-3 dielectric which is actually better then Teflon ,the interconnect was also respectable I didnot find anything dull in my system ,ifyou wanted more detail the goldEclipse 8 excellent .
myself wanting very good detail but want a bit of added warmth , the clear reflection does both well , the clear reflection speaker cable excellent but $1k
more then the Wireworld and very detailed and balanced blends well with most interconnects . Their power cords not as good as their audio cables IMO.
