Both Croft and LFD work well with Harbeth speakers. The the LFD sounds a bit better than the Croft regardless of speakers used. I carry bith LFD and Croft, both being favorites of mine. If you are possibly still in the market, I can actually send you both a Croft and LFD to try in your home for a couple of weeks to help you decide. BTW, congrats on the 30.1, the 30.1 will keep you up late at night listening to music.
