If you really want Schoeps, then my advice would be to hold back on the AKG's, because (i) they aren't as good; and (ii) it will rob you of money that could be put towards saving for Schoeps and delay your final destination even longer.
I feel like this is pretty subjective. It doesn't sound like he is totally sold on Schoeps just for the sound, but mostly from the size of the set up.
Personally, I'm not a huge fan of the Schoeps sound. I know there are others who are in that same boat. I've been running AKG actives (61s and 63s) for a good while now and and the two other guys I've taped with the most in the past both run either MK4s or MK41s (or more recently both). Obviously a little personal bias is at play, but 9 times out of 10 I prefer my source to theirs. That is not to say AKG is the be all end all mics, but to me personally they have a better sound signature than Schoeps.
To be fair, Schoeps does get the slight edge in detail and clarity, but only just. The difference is small enough that, to me, it is not enough to be anywhere close to a deal breaker.
Just wanted to put that out there for a different opinion. When I A/B my source against a buddy's Schoeps from the stand stand, the AKG feel a little too bright, slightly thin, but 'open' while the Schoeps feel a little too 'thick.' 'Dark' is thrown around a lot, and not a great description in my opinion, but there is something about the lows, or low mids that just seem to fill the recording. Nothing boomy or anything, just something that seems to fill the background, making them sounding stuffy.
My two cents. In my perfect world I'd choose something in between the two sounds. But I'm not looking to move around mics so am happy with the AKGs at the moment.
