I've finally put aside $1500 to go towards a pro-level mic pre. I've read here on RO over the past 6mths about various prefences for clean vs coloured mic pres. I've listened to the Sebatron tests performed by Kurt. I would like to know the forums thought on a mic pre that would best suit R&B and ocassional hip-hop. In the circles I travel, most would point me to the Avalon 737. I haven't seen the Avalon mentioned nearly as much as Great River, Vintech, Amek, etc. My mics are the SP C-1, Cad M9, Rode K-2, SM58, and Octava 319. The forums advice would be very appreciated.
