I would go even one step further and say "every source device does require unique tweaks to get optimal-for-your-taste results".
As far as original post goes, you are comparing different products (CD vs. LP, I assume) that were processed differently and should hardly expect them to act in the same way. Even if everything after the disc itself is perfectly aligned in the universe (which it probably is not). For that reason, both Michael Green’s and cleeds’ inputs may be correct in their own ways. If it is about listening to music,you may need to tune/tweak each set-up to achieve the sound you prefer on both or, if academically trying to compare analog vs. digital, you may need to digitize the record first.
I guess, in theory, you could also press a record of your CD and see where that leads you. Who was it that said that inconvenience is not that important in this sport? It was on another thread.
