Spending on dac vs amp

From a purely economic standpoint, a dac will likely depreciate in value faster than an amplifier due to the rapid advancements in digital technology. Something to consider if you plan on upgrading/reselling down the road. I wouldn't pour money into a dac until I had an amp that I liked and worked well with my speakers. My 2 cents FWIW...

You will get all manner of answers ranging from spend a majority of your budget on the source to the majority on your speakers and everything in between. My view is that buying equally capable components across the playback chain that are synergistic is the most important. No use spending huge $s on the source if you have crappy amp/speakers because you won't hear what your source is capable of until you upgrade the quality of the amplification or speakers and vice versa. This does not necessarily translate into a 50/50 recommendation but as a starting point, that would be my recommendation.

An integrated amp is a preamp $$$ and an amp $$$.
The preamp can be pretty simple, and an amp needs to make good power.
The difference between a equal price integrated amp and a DAC would be the integrated amp would sucl.. big time.
So I say spend it 90% on the integrated (from between the integrated and DAC only, not counting speakers)
And buy a used $250 DAC.
So for $8000. Spend $3,000 on speakers, $3,000 on an integrated amp, $250 on a used DAC, and $500 on a CD player, (or just buy a CD player like the Sony 5400 for $1,500. And the last $500 on cables.
If you also want a TT. then:
$2,400 on speakers, $2,400 on integrated amp, $800 on a CD player, $800 on a used TT, $500 on a new cart, and $500 on a used phono preamp, $600 on cables

A $250 DAC in a $8,000 rig, you're joking right?

It all starts at the source, why skimp there? NOS and newer cheap wall wart P/S DACs can't compete with newer high res DACs, there's no comparison.

I'd suggest a 30/20-25/25 for an Integrated/DAC. The other 50% on speakers and cables you'll be well on your way to a very nice rig.

Spend only $250 for a used DAC? Geez, how horrible that will be! And in a system of otherwise fairly decent performing products? NOT! You're pushing your luck to find any DAC, new or used, for less than $500, and probably closer to $1000, that will have any chance to bring the music to any level of reality that you would expect the other components to achieve. Spend more on the DAC and look for a good deal on a used CDP for $100-200. The difference between DACs is magnitudes greater than the difference between transports.

And $3000 for an integrated? What? A top performing line stage from ARC (LS5), CJ (Premier 10/14), BAT (VK5) from 10-15 years ago, can be had in the $1000-1500 range that if matched to a SS amp from the same company or others like from McCormack, would easily be less than $3k and pretty much destroy any $3k integrated amp. And you'd have $500 or so extra to get a better DAC.

There are so many phenomenal speakers under the $2k range that for an $8k system, I think you will be mightily impressed. No need to spend more at this point.

I'm a huge proponent in putting top-tier cables in a system, but I'd start with DIY or low-cost speaker cables and stock power cords. The only exception would be to invest a few hundred for an IC between the line stage and amp where it makes a major difference with line stages like the ones I mentioned.
