I have the Rogers High Fidelity KWM-88 Integrated Amplifier. It’s very similar to yours. Get ready to welcome in excellent gear. They are a good example of getting what you pay for.
I have not cone across many other Rogers customers but the few I have are also delighted.
Try it with your power conditioner and also right into the wall. You mighe be surprised. I also auditioned power cords and found one I prefered.
I rigged up a pair of quite fans above to suck up and disapparate the heat. This isn’t necessary as the amps are designed and overbuilt like few are but because I always have used small cooling fans. I had Roger mod my amp to run KT-170’s.
What Magico’s do you use?
