I think it has been discussed on the forum : a very good solution is Takstar CM63 + 3UAudio capsule(s) > 42€ + 120€ to get a really nice cardio SDC...

@Recording Engineer let us know please when you receive the 92€ Ali SDC mic (Schoeps look) and how it sounds with the chineese original caps.

Sure! There are a number of really usefull mods described in this thread, nicely summarized by @Voyager10.

You specifically mentioned to pair the CM-63 with the 3U capsules, but it yields a slightly different tonality when compared to the CM-60 + 3U combo, which I liked better. It's a bit flatter in the highs. I assume the differences are caused by the different back chamber and slots design. I'd suggest to also consider the Alctron T-02A instead of the CM-63, which I expect to sound identical to the CM-60.

You can hear the tonal differences in @joulupukki 's Blind Test (link below). Though both the CM-60 and CM-63 have slightly different KM84 style circuits, both circuuts are dead-flat in the highs, so I'd reason that tonal differences in the highs should be caused by the capsule/body combination.

Having done the KM84 "project", the S502 Mk2 capsule similarities with a Schoeps MK4 triggered me to pick up cloning a CMC6 MK4 as the next project. Just not with a standard Schoeps circuit, but my own.

@jp8 your DIY seems very attractive... so after a "Jan S502 special circuit" we'll have a "Jan Schoeps custom build" ?

Great ! Oh, I forgot Xmas is approching (Santa Jan) ;) 🥳 (y)
