I'm very impressed with how much the HE1000se can scale between X9, K13R2R and the A90 Discrete. The X9's AKM Velvet sound veils some of the HE1000se's upper range capability which in turn reduces some of the brightness whilst still retaining detail, I talked about this in my thoughts on the X9 back when it first arrived. The K13 R2R retains much of that signature whilst losing out on a very minor amount of imaging and soundstage articulation, though with the linear power supply that is restored and elevated to X9 levels for the most part.
Now, on the A90D this is where things get interesting, the HE1000se feels more fuller in the mid range and upwards, though there's no veil as the Discrete is rather transparent, so being fed by the Warmer R2R I am hearing layers that aren't being heard with the K13 R2R or the X9 - On top of that the brightness is elevated but not fatiguing - Though because it is transparent, songs that aren't mastered with care can sound more "digital" than with the X9 or K13 R2R if that makes sense.
A90D still has smoothness and warmth, but it does not mask away any of the headphone’s upper end capability, it just takes in whatever the source DAC is capable of and relays that right to the headphones in an honest-transport kind of way only adding some smoothness/warmth in the process which enhances the lower to mid range frequencies.
It seems to be a great pairing.
I suspect the Arya Stealth would also scale to a similar degree given how close the two are to each other in sound.
More than happy with this. The HD600 does not portray the same level of scaling, sounds like a HD600 on all, which is no bad thing.
