I am relatively new to audio recording. I want to buy a "kit" that has: Large diaphragm microphone WITH a power supply (not battery powered) for high-quality vocal recording. I don't know if the Phantom power supply/batter makes a difference but I assume the battery is a cheaper alternative with lower quality results. Headphones for monitoring I want to spend less than $350. I looked at Presonus 1box Audiobox Recording Package but I'm not sure if it's the right thing for me. For that price, $250, I could buy a microphone kit and headphones separately for less money I think. Could you please advice me what I should buy? I am using a PC with a standard (integrated; very simple) audio card. I also have a USB card in the PC. Thank you.
