I don't think 73max compared the Terminator II with the Terminator Plus but I could be wrong
You are correct, there is no mentioning of the T2, my bad I mixed up both.
But I thought it was particularly interesting from his comment that he tested both Gaia + Terminators and was close for him, you on the other hand have a different but yet valid perspective which validates the obvious that the + sounds better than the non plus model, I missed your earlier post with your comments, allowing enough time for the caps to break is important.
I can only speak for the Terminator (original model) which later I upgraded with the second DSP board. Note I preferred the Amanero board sound over the upgraded board during its first few firmware iterations, then around October 2019 the firmware update (think it was 3.3.2) was released and that improved the sound of the new board over the old Amanero. At some point I am planning to get either the 2 or the + but that's onhold for me now.
In other words, the R2R boards and clock modules that test the best are sorted for these DACs. Whether that's worth the extra ~$2K I can't say. I haven't heard the T2Yeah this is a good topic, I think it could, this is all related with production batches, resistor drift and linearity and the such which is all related for these ladder resistor DAC's.
