I recently (about a month ago) received my repaired K300i back from them. I have always found them slow to respond, but they do respond. Sometime a phone call worked better than email...
I really love the match of Krell to both my Xstatic EC/Xs and my Totem Element Metal V2's
I did not know about Rondi's passing. So sad, and I hope they all recover and thrive. Too many good people and companies are no longer with us.
