I'm interested in opinions on the Warwick Quadruplet preamp. I've looked through the archives and seen a couple mentions that it sounds good (sort of SWR IOD-like), a couple mentions that the output is pretty low (also IOD-like). Anyone have any more comments or recent experience? Right now I have an Alembic F-2B and a SansAmp BDDI. I'd like to consolidate the clean and the dirty into one unit - I've been thinking about the IOD, but I just noticed the Warwick for the first time.
