MK22 gets the vote here on a first loud playback on headphones (ATH m50)
but after listening more , i feel like Schoeps is neutral -doesn't mess with the source much ,where all Gefells have some nice low mid colour which i really,really like - it adds something emotionally to the performance and it's more apparent in second set of files .
In the end i'd probably choose some Gefell for final mix and i bet all my clients would choose Schoeps - it's somehow safer choice .
I must say i usually prefer really "coloured" (darker ?)recordings that's why i prefer MK22 to MK2 too ,but really all these recordings sound damn fine and there's no wrong pick here .
Thanks for posting these
