Is it universally the case that re-skins aren't very good? I've heard a lot of bad things about reskinned Neumann capsules, but I have a CK12 that Tim Campbell reskinned and it sounds good to me.
I have been enjoying my CT12's (Tim's remake of brass CK12) for years. Sometimes it takes me a LONG time--like years--to truly decide if I like something and it took me at least 1.5 years to have full confidence in the main mic I had built that uses that capsule. The CT12 has delivered long term satisfaction for me. Even though it's not 'apples to apples', to put it in some perspective, I always take that particular ELA-M250-ish mic to vocal sessions, but never even think to take one of my AKG 414-EB's (silver) with all original brass CK12's. YMMV. And the only true test, which I doubt will ever be done by me (or anyone else for that matter), would be also owning a good ELA-M250/251 at the same time as my mic and seeing which I would prefer in the long term.
klaus...There are several reasons for this bottle neck in quality: obsolete materials (certain PVC formulas), manufacturing secrets to block reverse-engineering by (largely off-shore) competitors, thus avoiding losing the ultimate competitive edge companies like Neumann possess. Then there is the lack of good ears, scientific rigor, talent, intention, passion and tenacity- all of which are required to succeed in coming up with good-sounding capsules worthy of comparison to the historic greats.
Please note that I am not
negating, or minimizing, what Klaus is saying.
