You need th900 with cables upgraded to ZX2 TRRS for the best of this combo. It is heaven! There is nothing like "doing in a pinch" about this combo. If you use stock cables and adapter....you wouldn't get the best of it. TRRS on zx2 is "what I wouldn't go without...let's say" I can't stand th900 out of RXV-477. I know it is not a proper headphones amp. But it is not a weakling
.
Sound adjustment with maxed out volume is "excellent"
. I tried it with all 5 maxed out, no clear-bass. Tried on tracks that I know well enough to analyze.
1/ more volumes
2/ no distortions
3/ All trebles details and extensions are vivid and clean! More battery drainage, which is a good sign
.
4/ works well with Gonemad and Onkyo
Now, even with clear-bass maxed out, I couldn't even hear any distortions. Sound-signature changed ofcourse, battery drainage happens. But it works flawlessly
Then I proceeded to disable the sound adjustment, it immediately raised the volume.
*cheer* one more discovery that is too well-done
and most important.
After all, it will come down to preferences and what you personally love the most. Happy hearing
I personally prefer sound adjustment off and Onkyo or gone mad for player app
