Simple answer: you have to be very fussy with digital, I repeat, very fussy. Lack of attention to detail will give you loss of fine detail structure. Every time.

It is with everything: with digital, with analog, does not matter. What matters, digital designers often don't understand well what goes on in analog domain, thinking digitally.

It never ceases to amaze me the number of people
who use ' digital ' scopes ....
Anyone can see the steps on the traces, but yet
seem to be ambivalent to the ability of the steps
to hide sensed glitches ..............

Exactly. What's being dealt with in a CD player, say, are always analogue behaviours, with some parts of that having a digital "meaning". Analogue can always adversely affect, interact, interfere with other analogue, and thinking of what you're dealing with, with that understanding has to be of prime importance if one wants "good" CD sound.

I tell people anywhere that today, more than ever before, you must get a home paid off or you will never be able to retire... not as long as you have to make monthly house payments. And, making that happen is becoming harder to do. But, you've made it and are able to retire.

When do you make the big jump off and free fall? We'll have a party for you over here in beautiful, sunny downtown Cool, California!! BBQ and a glass of wine on that day. -Dick
No mortgages here not that I like to rub it into anyones face. Not my style, I can't quite figure your angle on this.

Is it the digitizer or the display steps you are seeing?

If you know how to use the tool to see what you need to see it matters little if its digital or analog. Sometimes digital is way better for seeing "glitches". If you don't know what to look for sometimes neither digital nor analog (nor analog distortion analyzer nor DSP) will help.

I have a couple of other FFT units -- one digital scope made by Tektronix -- will do up to 300MHz FFT - 1-2 GigaB/s clock ...no steps seen. But I want more bits for audio.

Its just thrown in there for any one who isnt close to retirement to think about.

So? When is your last day?

It looks easy from "digital" point of view, until you start looking at gain and offset calibration issues, reference voltage stability and noises, and similar analog issues...

How many bits do you want from SACD (DSD)?
