I have purchase two C214s for some clarinet sonata recordings.
( the mellow tone it gives (natural and just like what I hear myself real life). It has a boost in the high which is quite significant on my instrument (e.g. key clicks, sound of air getting into the clarinet is prominent) which is not very ideal but with a good interface and a bit of balancing on the high within the DAW it can be completely eliminated.
If you love the AKG sound, the high boost is very useful especially for vocals, guitars (can check out numerous vid on YouTube) and wind instruments going into effects - a lot of details (air sounds, overtones, slaps, key clicks) on articulations. ( in all, brilliant mic, absolutely value for its price. Just a bit of work in the DAW, it'd be giving you as much as you get from a recording with 414s (I think you need very very proper headphones/speakers to tell the tiny differences even when comparing A/B). If planning to get 414s, why not go to a proper studio where you can do very serious stuff with a collection of AKG Neumann DPA Tele etc? ;)
