I'm very interested to know how you fare in this particular 'quest'. I also have an I5, which I love, but mated to JA RM7si Sig. For my listenning levels, this is sufficient power; however, I've been thinking about a tube pre, preferably with a good phono stage.
Not having ever heard the Hawk/I5 combo, I can't comment on the 'slight bloat in the upper bass/lower midrange area' you speak of. I have not noticed this in my setup.
