Another Ananda fan reporting in :
It's my favorite headphone, and I own a bunch of sennheisers and akgs alongside, I kind of knew that the easy drivability of the Anandas had to have some kind of a drawback, but these results are still shockingly bad haha!
But comparing side by side , I love it the most and I don't hear any distortions, in fact I find it clearer sounding than my hd650, 660s and akg. I have huge ears though and the sennys are more like on ears for me, while I get the best fit with the huge Ananda cans. I do use heavy subbass eq though, otherwise no eq...I need auto eq peq with my other headsets, but the Anandas sounded wonderful clear from the get go.
Here in Europe its way easier and cheaper to get hifiman planars since they have a warehouse in Poland with alot of open box deals, no custom charges like with he6se, Dan Clarks , drop models etc ...and you get to pay in USD . Payed around 500 USD so around 400 EUR at the time. I was considering the aeon closed ones which had good measurements, but it would cost about double the Ananda .
