I agree with the general sentiment. It's garbage in / garbage out, and you want the source to produce the best possible sound.
But when you consider your budget, and if you want to stretch $1500 as much as you can, there could be better ways to spend the money than buying a $1500 CDP. For example you can allocate $500 for a budget entry level CDP with good modern DAC, and upgrade your $1500 amp to $2500 amp.
In my previous experience, I've heard more variety in sound of amps under $3000 than CDP under $1500. Amps in $2000-$3000 range tend to differ in sound from one another. Modern CDP under $1500 tend to sound more similar than different. Notable exceptions are exotic DACs (NOS, tubed), or older generation (early 2000's or older) models.
IMHO the balance among the components is just as important, and you don't want to over-invest in one component.
