There are a few things that should be generally accepted about DACs at this time:
2. There can be the lowest correlation between DAC price and actual DAC performance in total musical enjoyment. For example, the difference between a really good $2,000 pair of speakers and a really good pair of $60,000 pair of speakers will be MUCH bigger in terms of sound quality improvement than a similar DAC counterpart comparison. DACs just don't have as much variability in price/performance as some other parts of the system.
That is debatable, and it depends on what you are looking for. If you look for overall performance perhaps you have a point, even though I am afraid that a $ 60,000 speaker, with proper amplification, may lay bare weaknesses of a $ 2,000 DAC to the point of nuisance. But if you look for specific areas of performance such as timbral resolution, for example on the micro-vibrations of a violin, then a $ 60,000 DAC on $ 2,000 speakers may give you a better return than a $ 2,000 DAC on $ 60,000 speakers.
I have once heard $ 2,000 speakers driven from a $ 60,000 vinyl rig, and the resolution was amazing, even though of course the weaknesses of the speakers in other areas remained present (it was set up that way because the owner's main speakers were in repair and he played with his spares). Like some others, I am a strong believer in source. I know that at this point I would probably make the most gains in timbral resilution by going from my $ 5,000 DAC to a $ 20,000 DAC, for example, without changing my amps and speakers which compared to many super-rigs are of modest monetary value. And my $ 5,000 DAC is much better in this area than some $ 2,000 DACs that I have auditioned in my system.
Yes, amps and speakers are important, but so is the source. And a $ 2,000 DAC usually does not work miracles.
