I attended the Rocky Mountain Audiofest in October and heard the K-300i, chatted with David and Walter, and based on what I HEARD I extrapolated that of course the dedicated amp and big brother to this unit - the Duo 300 XD - HAD to sound AT LEAST as good as the baby brother “all in one,” and I was right.
I have owned 3 Krell amps since the mid 80’s and most recently was in possession of the 400 FPBcx. I am happy to report this AMAZING amplifier is easily beyond impressive, delivering all of the wonderful sonic qualities alluded to in the post here. I thought it was impossible that this eco-friendly Class A amp drawing only one watt in standby mode could equal, let alone surpass the sonic quality of my 400 FPBcx “muscle car.” The amplifier BLEW it away. Just fabulous. As an aside, I had listened to the NON XD version and was not compelled to trade up. There is magic in what David accomplished here with the introduction of XD platform and there is simply hands down, no comparison. I traded up to the Duo 300 XD and couldn’t be happier. The amp drives my Confidence C2 speakers and am using the Krell Foundation prepro for both 2.0 stereo and home theater and I am in musical nirvana. This amp is musical, involving, highly detailed and delivers an entirely immersive experience with a huge soundstage . At around 10K it is quite a value.
