Yes thats true phantom has the treble tamed by quiet a good margin. Enough in my opinion to not consider them for classical genras but so perfect for spotify and picky trebly songs. That was my case...
But I miss sub bass and better shimmery bells alike treble chirps, cant have that on phantom.
Thought if valk have the juicy treble and the sublime sub bass with the weapon IX and keep the phantoms outstanding authoritive mids all this could be a straight gift from heaven )
And effect audio cleopatra. Oouuu olala yes please I whant it ) ) )
Ive heard that one of the reasons for the tamed upper treble was actually feedback from Zeus. The tamed upper mids, not sure but it was an issue a lot of asian audiophiles had with Phantom. Female vocals were very veiled.
Even with a pure occ silver cable off the balance off the 1A this was a huge problem.
The sub-bass is insane on the Phantoms, easily the best for BAs. I take it you're not a fan of DD bass? I suspect the Weapon IX DD would match if not surpass it on the Valk. Mid's are BA still but its possible they retain the Phantom's, though it would need a lift in the upper mids for me.
The EST is a concern for me given the criticisms for recent tri-level hybrids and the treble. Hopefully Empire opted for a tuning that doesnt go in that direction.
Cleo comes with the Wraith (Explaining that almot 4k price tag). Valk has Eros II.
Either way the 1A/1Z should have no problem driving either on high gain. And most likely no hiss, based on my experience with the Khan.
