Ive been looking to pick up the FocusRite ISA One classic, and am feeling pretty good about it, but I was wondering if there are any other mic preamps in this price range that can rival it or top it. It will be for vocals, not instruments at this point so Im looking for a quality preamp in this price range that can bring a microphone to life so to speak... The mics that Id be using are along the lines of an SM58/Beta 58, EV RE20, Studio Projects c1, Sterling Audio ST-51, pretty much all in that range of mics. I want a nice rich, clear and crisp tone, so any suggestions would be very helpful. Im looking for a quality preamp, not quite at the entry level, but the next step, enough to hold me over for a while until I have serious money to invest in equipment like this. I was told the ISA is considered to be in the 'good pre' level so this is what Im looking for. However, if I can get similar results with cheaper mic pres Id love to hear about that also.
