This is perhaps an old question, but... Is there enough that is special about the DB750 to scrap a separate Pre / Power Rack? This seems sort of like a Macintosh vs Open platform PC kind of question. Perhaps, another way to ask is when comparing the DB750 to a high quality rack with an Alembic or Demeter Pre matched to a high quality Power amp, does it become a matter of personal taste, or are there definite performance advantages that the integrated DB750 provides? I can't tell from all the various discussions whether this is a tomAto / tomahto question or whether there are intrinsic and significant tonal differences. And thanks to everyone on this board. There is just no practical way to look into this down at the local Guitar Center.
