dac chip vs analog stage as to sonic impact


when buying a cd player or dac, which has more impact on the sound of the component, the dac chip or the analog stage ?

to what extent can a tube analog stage "offset" the effects of a dac chip ?

if one were to assign a percentage contribution to the dac and analog stage as to the affect upon the overall sound, what might the numbers look like ?

Tvad...Checking the APL website I notice that the DACs which they use for the update are AKM. That's what I have in my Behringer DAC2496 which may be why it sounds good.
