I have the 211ia. Nothing but positives here too. Really nice unit. I am using SED Winged C EL34's w/ Mullard and Tungsol New production for the 12ax7/12au7. I almost don't want to listen to the 218ia, in fear I will have to have it. It's the 210ia that really seems to fly under the radar. I've only heard the 216, other than my 211.
