The HD598 is a tad more balanced and clear, but these low impedance headphones are not a good match for a receiver.
Most of the times, the headphone jack present on receivers has a really high output impedance, when you plug a low impedance headphone like yours (or HD598) the frequency response (ie, the sound) of the headphone is altered, there's a boost in the mid-bass that also appears less controlled or even boomy.
Little DAC/Amp like the Schiit Fulla or Fiio E10K are perfect match for this kind of headphones.
In my experience, the Beyerdynamic DT880/250 is one of the best headphones to plug into recivers with high output impedance.
While I don't concern myself with all the impedance and diodes and such of headphones, you make an interesting point I had not thought of.
That is the sound being altered by what I'm plugging into.
However, with my 518s, boominess is not my issue. If they were boomy I would have thrown them in the trash long ago.
I have tried my 518s with several Dac/Amps and the only one that showed any improvement was the Oppo HA1, but that is a ridiculous amount of money for someone like me that rarely uses headphones.
The Schiit Fulla and Fiio are designed for laptops which I do not use.
Oh, I think it might help to state that my listening is with Vinyl and CD predominately. (I don't like files personally).
