I am buying some equipment for doing some field recording, ambiental sounds, natural sounds but also machines, rocks, chains: everything i'll find on my way, both indoor and outdoor. The main purpose is collecting sounds for music making. My recording device is a Dr-40 Tascam. Microphones: the whole me/k6 collection (used at ebay ) Now I was thinking about slowly upgrading my mics to some more professional ones. I've just bought a used mkh 416 (paid 480€) and I am comparing with the me66(paid 230€): I still need more time to deepy understand the 416, at the moment i don't notice a huge difference (I am listening on some Adam A7X), for sure not a difference that justify the double of the price. A real upgrade would be the mkh 60 or the 8060, but they are both out of my budget at the moment. I was reading good things about the AT4073: would be that an option? or better to wait for more money or some luck on ebay and get the mkh 60? Or maybe better to invest more money on a recording device?
