Kuan -- have you listened to a SET amp? Awesome! If you don't want to mess with tubes (300B, 2A3, etc...) try one of the Pass MiniAleph amps. I have one that I sometimes run with the Fostex fullrange kit from Madisound, and it's great. If you want to spend a few bucks, try a Lowther setup, or build a Hedlund horn. Fun stuff!
