 I am using a class d integrated and it is using class d ice block power Amps in it. Weird thing happened changing cables has very little impact with this piece from power cables to speaker cables. I was told it is because of the very low input impedance. Has anyone else every run into this. I tried from my Virtue cables to wireworld to mit and straightwire.

 Lummy provides excellent advice. What gear, including cabling, is in your system earnie3?

 You might want to try a Shunyata Research CX series power snake.These did wonders when hooked up to my Red Dragon Leviathans.Even a Black Mamba is worth the effort.

 In order to evaluate this properly, certain prerequisites have to be met.

  • The sources must be capable of delivering the goods.
  • The preamp must be sonically invisible.
  • All cables must be properly treated on a burn-in device.
  • The speakers must have the honesty, to tell you what is going on upstream.

    I was able to meet the above requirements, when reviewing the following Class D amps:

  • Jeff Rowland Continuum 250 integrated
  • Jeff Rowland 501 monoblocks
  • Jeff Rowland 312 stereo
  • NuForce 9SE monoblocks
  • Rotel RB-1092 stereo

    We did not feel that the above amps (and I cannot vouch for other Class D models) were any more or less "sensitive" or "reactive" to the myriad cable looms we employed.

    Just like with any other amp, you have to pay attention to the quality of AC. That means investigating wall outlets, powerline conditioners, and powercords.

    Just like with any other amp, do not do all the hard work upstream, only to throw it all away via a colored, uneven, dishonest speaker cable.

    Just like with any other amp, speaker choice matters.

    Just like with any other amp, the more revealing, accurate, and honest associated gear told us exactly what and where the Class D amps' deviations (and strengths) lay.

    Because the Jeff Rowland 312 was far less inaccurate and distorted than the other four Class D amps, you could argue that the 312 was the most "sensitive and reactive" to cable choices.

    If you go to my homepage, you'll have to go back at least 6 years, to find these amps. But you will also see a sampling of the hundreds of audio products (scanning a wide price range) we used with these (and all other) amps.

    Yes, cables effected changes, but each listener would have his or her own judgment, as to whether those changes were small or large; plus, minus, or quid pro quo; inconsequential or significant.

    		 I have four class D amps, some ICE MODULES, some other modules. All have had a huge impact from changing power cords. That and vibration control. The two biggest tweaks impact wise.

    		 I do agree that the biggest impact has been power cords. the smallest impact has been interconnects.
