Differences between models of expensive vs inexpensive DACs

@jjss49 That's what I'd expect - the cheaper dacs would be more colored in various ways while the more expensive dacs would be approaching the same ultimate standard. Years ago I saw a comparison of the exact same studio shot made with two brands of lenses at the same spec. One was much more expensive than the other. The shots looked identical until they were viewed side to side, in which case the higher contrast and deeper black of the more expensive lens became evident. It controlled blooming better. It's really hard to notice that when not viewed directly against each other because our eyes adjust contrast.

OP,

How you use the DAC chip… how many… power supply etc… determines the sonic output. So, while the DAC chop as limiting factor, it is not… just one of a myriad of factors. Which is why long strings centered on R2R or ESS chips really just detract from the real issue. Even inside a DAC component… it is a system and making it sound correctly, it is a matter of all the components together.

old post below, fyi - perhaps a useful summary of the topic

as to what matters in a dac, let’s make this simple, even though it isn’t...

a) the digital (bitstream) input signal needs to be received and timed correctly for d-to-a conversion, so clock circuit and jitter reduction is key, this is done by electrical isolation, reclocking as needed

b) then the actual d to a conversion / filtering needs to happen with low distortion both in freq response and in timing (phase response) - this is done by the internal dac chip/circuit or discrete ladder network, depending on design

c) then the analog output (post conversion) needs to be prepared for output to the receiving device... this is done by internal amplifiers, or transformers, or some other method... very rarely is the output ported straight out of the dac chip (there can be impedance mismatches with preamps/amps/whatever device is to receive the signal to amplify to drive speakers/headphones you listen to)

d) all the above needs to fed clean and strong power so they do what they do without added noise, so internal individualized power supply design and quality (and power supply isolation of the analog from the digital sections) is absolutely key

so when knowledgeable people correctly say, "it isn’t just the dac chip (akm, burr brown, ess sabre, wolfson...) or the ladder chip (philips tda, etc etc) or fpga (custom circuit) that makes a difference, it is the IMPLEMENTATION of it", that means ALL THE ABOVE designed and working in concert to produce good analog sound, as a holistic system

’what goes into a dac to make it good’ class 101 now in recess

hope this helps

I have owned 3 DACs in the 5K range that sounded very different from each other, and also 4 DACs in the 1 K range or below that also sounded different from each other

curious... please share which 3 expensive dacs you tried... and what front end fed them their input signal... and if you don't mind, rest of your system, for context

many thanks
