Harbeth HL C7 ES

I've just ordered a pair and they should arrive next week. I don't have tube equipment, but I'll pass on my thoughts. I run a Marsh 400 amp, Monarchy 22C DAC/Pre and Classe transport. Does anyone have any thoughts on cables? I currenty use Nordost Flatline Gold bi-wire.

Wow, these 7ES's are fantastic! I just received my pair two days ago and they are humming with the Marsh Amp. What's interesting to me is that these speakers don't have that "artificial" transparency that you get with some high-end speakers. When I first started this search for new speakers two years ago, I was impressed by the airiness of some speakers. But, the longer I listened, the more artificial they sounded, almost as if they were "tweaked" to be breathy and bright (does this make sense?). Conversely, these 7ES's are much more natural, and sexier. Just a personal opinion. I'll cautiously explore new cables, and heard the negative feedback from REG and Alan on the Harbeth User Group. Still open to recommendations, though. Thanks!
