I am in the same boat. My DWs are being shipped and I have been scouring message boards to find a suitable amplifier. I really wanted to try a SET amp. Sean suggested an Audion amplifier that was far more than I wanted to spend. I have narrowed my search down to a Coincident Dynamo and Decware Zen 25th Anniversary. My main concern is if 8 or even more so, 2 watts, will be enough power to run the Zus. I was assured by both manufacturers that both amps are a fantastic matchup. I am still worried about having enough headroom though. I also considered the "Rachel", but since I will finally have some efficient speakers, I very much want to try a SET amp. Please share your decisions and findings with us!
