my shortlist for integrated Harbethsuper hl5 plus xd - please advise

@gryphongryph I am not sure if it came from Gene Rubin, but that's definitely a sign, that he carries both Moonriver and Harbeth

@grislybutter It did not.

I'm using Classe CAM 200 mono blocks to drive my Harbeth 40.1's. You may be able to pick these up on the secondary market. Terrific sound-smooth, no edge, plenty of spare power. This is the type of amp that Alan Shaw recommends=lots of brute power!!!!

You can’t go wrong with the hegal. For 4K on the used market, its hard to beat IMO. I have a Pass 250, Accuphase 380, Mac Ma353 and the Hegal. I can nit pick all of them, but it’s hard to find anything with the Hegal. Midrange is some of the best I’ve heard. Pass is superb, but $$$ and heat in a small room.

I agree with yogiboy on the LFD recommendation. I have two Harbeth systems; SHL 5+ 40th Anniversary and M30.2 XD. I use a LFD NCSE MK 2+ in each system. Great synergy between Harbeth and LFD. As yogiboy mentioned, Gene Rubin Audio is tops on LFD and Harbeth combination. 
Gene is super friendly and helpful. Well worth a phone call!
