So I just received the recommended components issue and something has struck me as odd regarding the classification of NHT's speakers. The Evolution T6 is placed in "Class A", and the Xd is placed in "Class A - Restricted Extreme LF" with a little note from JA that he wanted to place it in "High Class B" but that he "demurs to KR's class A".
After reading JA's takes on both speakers (including his follow-up on the "commando" T6 configuration), I would not have thought he would pick the T6 over the Xd. On top of this, he personally measured both systems in the lab and in his listening room, and the Xd clearly bested the T6 and even demonstrated deeper bass extension.
Kal and JA: Can you guys offer some clarification?
