Heard the LFD and Harbeth combo lacked the drive for Harbeth before. This person actually suggested a lower priced integrated in favor of LFD for just that reason. The name is escaping me... a british line but not Naim. Also looking to pick up a pair of 7’s. I enjoyed my time with the P3’s, but I want to play in a larger room ( 23 X 12 X 8), and the 3’s got lost in there. I also hope my Croft lights up the 7’s a bit more than it did the 3’s. I would think with the 2.5 DB difference it should be better. As far as good for rock, that may be another question. Kray- interested to hear your findings with some healthy tubewatts running the C7’s. I hate to say this but I’d like to hear a Cary Sli-80 in to the 7’s...the older version with all tubed PS. Enjoy the ride!
