I am building my first project studio and I need some advice choosing a good tube based condenser mic for vocals. my budget is roughly $500-$600 and while I usually prefer to buy used, the delicate circuitry of these mics makes me want to go for a new one so I can be sure there are no surprises. I have been looking at the Rode NTK but am very open to other suggestions. I would definitely like a tube based or at least a hybrid mic. Thanks!
