Is there a consensus on whether or not the newly released Xduoo TA-26 has any benefits over the DarkVoice336 SE? It seemingly has a lot in common, both amps implement the same tube size/configuration (6N8P, 6N5P), both are OTL, both have RCA inputs and outputs on the back along with AC power supplies. Specs are approximately the same. Do you think the TA-26 improved upon the internal design and/or corrected a couple of issues that seemed to commonly impact the DarkVoice, ie. noise, interference, etc.?
