OK, you haven't got the courtesy to reply.

I've got another suggestion for you. Why don't you put it where the sun don't shine?

If thats pointed to me dont you think you are being a little 'harsh'?

I did try what you suggested but it didn't make any difference.

You asked for suggestions.

I made you a suggestion.

You replied to various posts, none with any suggestions for tweaks.

I asked if the suggestion was any help.

You replied to various other posts and rattled on about drinking wine.

It's no skin off my nose, but I'll think twice before bothering to reply to you in future.

As you can see the 44.1kHz sampling rate replay is modulated. This is perceived as "metallic" or "harsh". It gets better with the lower frequency but still exist at even 10-12kHz.

The scope shot is a result of the barely 2+ samples per cycle vs almost 5. With a proper reconstruction filter they should look the same. Your scope is showing a lot of 18KHz harmonics which are inaudible to the ear. They may mess with your amp if not filtered but thats what the reconstruction filter is for.

No reason 44.1KHz can't reproduce a pure 18KHz sine.

Whatever problems 16/44 may have reproducing a distorted sine with lots of noise isn't one of them. Is this a NOS dac? Something is seriously wrong with that picture.

I'm with you. That's how one of my amps reproduced a sine wave until i added a zobel network to it.

That 18K trace is about right.

The 'Problem' with redbook is the 44.1KHz sampling - for the 18K signal, there are in effect 2 and a half bits to describe the whole wave.

It simply cant be done.

Add on the brickwall filter (which is in operation at this frequency), and you have the 'mess' of a wave that we see here.

In digital systems, the closer you get to (sample frequency)/2, distortion increases exponentially.
