In response to N5ZC’s request I just made this short video to provide a listen to the KPA1500's fans ... at least as they sound in my shack. Follow this link to view: https://vimeo.com/273064144
In addition to the KPA1500 the video also includes footage of my Alpha 9500 and Icom PA1 … each running with their fans at maximum speed … to provide a simple rather crude comparison. What do I think? I think that fan speed 1 and fan speed 2 on the KPA1500 are probably comparable to the fans that are installed on the other amplifiers as far as sound and efficiency are concerned and likely provide a similar degree of cooling at those speeds. And, I think that fan speeds 3, 4, and 5 (which are indeed noisy) provide the KPA1500 with enhanced cooling capability that is simply not available on other amplifiers.

This fan noise issue has me concerned to the point that I’m considering cancelling my order. While the amp won’t be on my operating desk, it will be on a rack next to my operating desk. Remoting the amp is not an option. Quite frankly I have no interest in remoting the amp. Is there anyone out there that has a KPA-1500 willing to post a YouTube video so we can hear the fan in action and judge the noise for ourselves? From the research I’ve done it appears that if you want a solid state amp, regardless of make, you need to be prepared for fan noise.
