I give Garbulky enormous credit for stating the case fairly.... and not leaving us trying to assume that "simpler is better" or "all modern technology is inferior to the old stuff".
Me telling my wife: "I just got a new CD player. But it's actually from the late 80's."
Wife: ""What? Why?"
Me" "Well have you ever heard of a multibit dac?"
Wife: "No."
Me: Well my current dac is a delta sigma DAC. And these are usually 1 to 5 bit DACs which approximate a 16 bit signal from CD's and modulate it using all kinds of processing to produce the sound. But back then they did not have that technology so this muiltibit dac is a true 18 bit DAC. Which means that every bit of the CD signal is produced by itself using precision laser trimmed resistors. These types of DACs are no longer really being made except by some small companies.
Back in the day these multibit units were very expensive to make because the resistors had to precisely matched. And this one is matched using lasers! The current delta sigma units are much cheaper to make and produce greater accuracy for a couple of bucks. But back then multibit dacs were very expensive. The difference is that the process of producing the signal was more simple and each bit just gets produced. So some say the sound might be better! How cool is that?
Wife: "Please stop."
I also have to give my wife enormous credit for putting up with my a$$ . It's hard to find audio enthusiasts you can yak on about this stuff with.
