Flavio...I have the Thiel 2.4s and I use the Audio Research Ref 110 power amp, which is lower power than the HD220 and I have no problems driving the 2.4s, which are harder to drive than the 1.6s. I have not heard the HD220 but if the sound is anything like my Ref 110s, I think the combination will be very nice: very natural timbres, neutral tonal balance, three dimensional soundstage and great imaging in space. Overall, very natural and smooth presentation. Some people would like more meat on the bones with both Thiel speakers and Audio Research electronics, but I think there is more than enough. Good luck. Hopefully someone who has heard the HD220 and Thiel speakers can chime in.
