Routeman21 I had been reluctant to post my experience with the KWI-200, thinking that perhaps I was the only one having issues with the amp. Firstly, Dan has been very supportive during my on-going saga with the amp.
My first KWI-200 I brought home, fresh out of the box, was DOA. It was shipped backed to Modwright, and a replacement built and sent out to me a few weeks later. In the few months that I have owned the replacement amp, the 4 rail fuses have blown once, and I have blown the main fuse 3 times. Similar to your problem, this past weekend the amp kept shutting down with a display error that indicated the DC bias issue. It has since been working, but now with a noticeable pop noise in my right channel during start-up. Dan thinks the DC bias might need to be adjusted, so it will soon be shipped back to Modwright.
To worsen matters, I asked the dealer if I could get a refund should I decide to return the amp, and his answer was no, and that he could offer me a store credit, which is not the answer I had expected. So in my case, the only option is to deal with the amp issues
not one of my best audio experiences.
That said, the amp has been very enjoyable when working, and Dan has been very helpful.
