this is a case where specifics drive the outcome, generalities are fun coffee table chatter, but are inconsequential
I think this is gospel. It all depends. But, as so many above say, typically a great preamp is better than no preamp. I'm glad this is working for you though. Don't forget about how lucky you are to have stumbled on your no-preamp-situation when you make your next move....I. mean, if you make your next move. :).
