I don't think this is a goods news for me. My cans (ATH-W1000, ATH-ESW11LTD, Martin Logan Mikros 90, ATH-W5000 (just ordered)), are all in the bright side. And I found that it pair well with X3, except for I like to have a better details.
I test ESW11LTD with AK120, this combination is too bright for my taste
I also try 901, really appreciate, except for it has a little bit too warm and a bit too much body, but details are very goods and have a lush sound that I love.
So, regarding your comment, I may have to cancel my pre-order and test it first. If it do sound bright, that will be absolutely bad news, since I have to pay much more for 901 with balance card
Thanks for info!
