The only question is WHY?! DX90 has decent amp, capable drive even HD650, not to mention low impedance IEM's.
I've never seen a definitive answer to whether the DX90 can comfortably drive the HD650s.Have you actually tried this combo yourself? Does anyone else have a positive opinion on this?
They drive my HD600's fine. No complaints. I usually have them at 230-240 volume wise. However when I put the dx90 through my neco labs twin burr Brown headphone amp the HD600's pack a lot more wallop. Its not so much that the DX90 has any problems driving the HD600s its more a case of audio preference for me. For softer more dynamic vinyl rips my amp can be quite beneficial in lifting the low/mids/high.
So YES they can drive them but one MAY prefer the change in audio 'quality' DEPENDING on what one is listening to
In summary YES they can comfortably drive the HD600's (for example) but some may prefer an amp depending on the type of recordings they are listening to. If you listen to CD rips then absolutely no problem due to the loud [lack of] dynamics !

Ps: In case you are worried about the 'vale'd' aspect of the cans the gain boost really brings the cans too life.
