Can somebody explain why it has those two blue transformers that look like output transformers? I thought it was supposed to be 'direct' drive from the tube bypassing any transformer? Maybe I am missing something.
I too had thought the T2+ amp is OTL, but apparently not even an OTL design has an output impedance high enough to handle the uber-high load impedance of the H2+. While most transformers coupled to tube amps lower the output impedance for the sake of driving low impedance headphones, the transformer in T2+ was apparently designed to increases it. Of course, this would make the T2+ utterly incompatible with most headphones out there, not even with the 600-ohm Beyer T1.
As you can see in this article, it seems that the TakeT H2+ headphone belongs somewhere in the "fantasy world."
