Ok I just listened to that, it was actually better than the Assimil stuff because the pace was more natural and the prosody better. I actually got most of it just listening so it was very nice. Not as good as his singing but better than the Assimil.
I said I'd put up a review of the Assimil, still working on it due to lack of time and because, frankly, Markos pushed the bar higher with his review
But my notes on the first 26 audio lessons are basically the following: the slow pace and histrionic delivery can be annoying to most (but the mod Greek version is the same!) problem with assimilation wherever enclitics turn up. I think this is more due to constraints on the pace of the recording for Assimil because, as I said, the mod Greek similarly suffers and his other stuff is good.
Incidentally, you could do worse than listen to modern Greek stuff. Yes there are many problems from an ancient perspective but its the best way to naturalise certain tendences, e.g dealing with accentless clitics, how certain sounds coalesce and separate.
I find the tones a bit histrionic incidentally, a bit too...musical, but then I should point out that I'm used to the tones of a language like Punjabi which are slightly more...subtle.
