I am about to begin the long journey to find the right pre for me. The pre-power setup is new to me and I don't have any experience to speak of with bass preamps. I have been doing a lot of reading on the forum and like the buzz about the BMAX. Since I will be likely to go through a bunch of preamps I want to stick to the used market for now. I want to begin my journey with the BMAX but they are difficult to find used at this point. I was wondering if anyone has any experience with the 383 and BMAX and can shed some light on the differences between the two. The 383 sounds interesting based on the lower price and availability. I would just like to have a little better understanding of what I'm looking at.
