You can check out Sangram too. I'm using his First Watt inspired Class A amp to drive the Harbeths.I looked up Croft, thank you for the suggestion but they are beyond my budget right now.
I agree here too. In this case though I quite like the speakers and so will stick to them. As for substantially raising the budget, well that can not happen at the moment. May stick with what I have if I can not find a good used option.
