Yannis makes some truly fantastic, competitively-priced hand-made cables, and in my experience has an intrinsic understanding of how cables 'work', in a hi-fi sense, like few others I know, but he does sometimes tend to 'disappear' and stop answering his emails, for no apparent reason, which as Rob's currently experiencing, is rather frustrating!
So come on, Yannis, surface from wherever you are and fulfil Rob's enquiries, as 'hiding', mate (presuming and hoping that you're well), is not good for your reputation!
