Hmmm... Chord Hugo's output is probably less than the Bakoon but because of the faulty (somewhat) design it does not even fare as well as the Hugo's headphones outputs? Interesting.
So Hugo's output, despite not putting out a lot of power, does a good job with planar-magnetic headphones that require a good deal of power @Currawong?

Currawong, there are many super reviewers in the site, but for me you are definitely #1 Reviewer on the site, why? i love how honest you are when it comes to giving starts, and the biggest example was the Fiio X5, 

thanks for this awesome honest review  + the honest rating as well.

btw does the HPA-01 sound Dark from the current output?
