1) Which accounts for the most sonic improvement? A quality dedicated CD Transport or a Quality DAC?
2) If a person could assign a percentage... by what % did your cd transport improve your sound? By what % did your new dac improve your sound?
A manufacturer of a high caliber who knows how to make a top notch sacd/cd transport will also know how to produce a top quality dac. It is their integration of the two and optimization of signal paths, etc that makes it sound immaculate.
You may think that you can do a better job than the high caliber manufacturers... mixing/matching the different transports, dacs and wires made of magicdustium. You may think a lot of things and imagine yourself to be some type of audio master chef/sound master....but, you may not succeed. The regular guy sitting at home just doesn’t have knowledge/expertise on the nitty gritty like the manufacturers do. Nevertheless, some will need to spend tens of thousands before they admit defeat (such failed adventures begin to show up on the marketplace).
