I would say your transducer should be where your preferred sound be tailored. Your amp and DAC should be as neutral as possible. IMO.
If you like a warm sound - go for something like the LCDs, HE1Ks. If you like the neutral sound go for the HD800 types.
With a neutral setup you can achieve this pretty easy. I'm not sure you want your chain imposing its sound and making every transducer you have sound the the same.
