He said "This is where the lackluster dynamics of the PD's headphone output gave me sadpants.". This is the same as what I've found with all the Audeze planars if they are used from an amp that doesn't have the use of planars in mind in the design -- the sound is disappointing. Likewise high-impedance headphones such as the HD-800s from amps that can't consistently provide good voltage swing -- the soundstage sounds collapsed. I'm lucky though, in that I have amps here that do well with both.
I was referring to
cizx's comments that the Audez'e headphones he tried do not sound as musical as T1 - Quotes :
"Compared to the Beyerdynamic T1, [LCD-X] is more neutral and, I think, less musical (but I love the tonality of the T1)"...
"I still haven't heard [the album] sound better than it did with my T1."
Doesn't matter what amp is used, any Audez'e headphones do not have as good 'euphonic' sound as T1. It is even unfair to compare them, the electrodynamics will always trump the planar magnetics in this aspect of sound presentation and on top of it T1 is a master in its class. If I had to give an analogy to tell the difference between an Audez'e headphones and T1 of the ease-of-flow and liveliness of sound then I would say an Audez'e headphones' sound is like a dance of a fat leaden footed dancer and the T1's sound is like a dance of a young and graceful ballet dancer in her prime. Planar magnetics do have leaden tonality compared to the electrodynamic headphones. This shows that there are no perfect headphones, each headphones technology has its advantages and disadvantages and it is left to each one to decide what kind of sound one wants to hear.
