Today, I finally had chance to listen MHP1000 headphones with familiar tracks, powered by MHA100.
They actually sounded very good. Sounded like T1, but with slightly more bass and less grain, which are positive improvements IMO. Only issue is slightly decreased soundstage, but it is still quite big enough.
The finish and the feel of the headphones are indeed luxurious enough... almost hard to think it is made by beyer.
As a person who heard pretty much all of the high-end beyers so far, I can say this is Beyer's best sounding headphones yet. If it were 1.5USD instead of 2K, it would had been relatively competitive headphones and very good high-end closed headphones.
