I have been browsing the forum looking for opinions on pre amps and have not found anything very up to date. I am looking for a solid pre amp for mostly screaming vocals. My budget is around $500. I'm currently using an at4050 and a Nuemann KMS 105 (mostly the nuemann) I am borrowing a symetrix 528 and like it but need something for myself and later projects. Would you recommend the 528 or can I get something better? Thanks!
