Indeed. Currently I am feeding my DAC SPDIF over an 8" twisted pair (one signal, one ground) of CAT-5e 23AWG solid. Terminations at both ends are soldered. It runs through a very large ferrite bead (intended for a power/mains cable).
Sounds excellent to me. No worse than the 4 foot RCA/coax sounded, and much less bulky and annoying.

Any Parallel with Video Upscaling? Anyone?
I have a Sony 720P projector and I use it with Off air TV.. The Off air signal quality and picture on Sony is Fantastic. Channels transmit they're signal in either 720P or 1080i formats..
The screen is about 100" diagonal, there is the screen door effect with the 720P projector but the image is sharp, color is very natural, skin tone best I've seen.. Blacks are satisfactory..
Upscale the 720 native resolution to 1080 TV or projector and things change, SDE is not noticeable but the rest of the image is not as good as Native to Native 720P with the Sony..
see my point?😉
yes. so much so, I gave away all my LP system.... TT/arm/cart/pre-pre, riaa phono and all my LP collection. never regretted it for even a second.
I often use 24/96+ HD downloads and play them from memory files on usb memory plug-in to a DAC (BenchMark DAC 2) via an Auraliti PK100. CD's are played on a Alesis ML-9600 MasterLink.

Hello.
Yes !
I agree with you
I understand your comparison. You make a matching between upscaling video and audio oversampling. There is also a phenomenon applicable to video and audio: the aliasing. (it's something else)
. The method of oversampling and interpolation brings something unnatural. The stairs are not a big problem, they are naturally filtered through the speakers and especially by the human ear. I already did an interesting experiment to record a 10 kHz signal on magnetic tape from the output of dac. I increased a few the record bias to accentuate the treble.Then, i looked at the signal with an oscilloscope. The stairs were attenued ! I then recorded some music on the tape recorder. I was surprised at the quality of listening. I preferred recording on the magneto (Revox B77, tape PEM 468 19cm / s). It was a kind of analog oversampling. I also like to record the output of dac on my Nakamichi 482 and especially my vinyls too!
This is a kind of afterglow that is also true for video (the time of color and brightness change by the lamp, retinal persistence are natural filters and induce a natural interpolation.).

A projector cannot display more than its native resolution, up-scalling is interpolated and in the case you mention the effect is not more resolution but an affect similar to dithering or aliasing as the previous post mentions.
I would say the effect is more like the addition of an optical low pass filter on high resolution digital cameras, it softens the image to reduce moiré effects and similar.

This DAC is able to faithfully reproduce the first seconds before and after the beginning of time.
LOL😀
I must admit I quite like its looks, but personally I'm a black box (or rack mount out of the way) person.

If you vibrated the projector and flashed up successive frames of the correct information perhaps you could increase the resolution of an image subject to human vision persistance.
See, miracles are available...

Yes, you can actually buy one. This is exactly how the JVC 4K projector creates UHDTV from HD chips.

Hi and thanks a lot for the very interesting thread and comments.
Just a kind request.
If someone has put together a nice digital source that satisfies him/her as much as analog please list the elements.
That would be interesting as well.
Thanks again, gino

I haven't found one yet that doesn't. I've had three or four different CD players, modified DCX2496 working with my laptop and a USB-SPDIF converter, an Echo Audiofire, an M-Audio 192... all worked exactly as they were supposed to.
Hi thanks for the valuable reply and sorry ... do you mean that you have been able to get satisfaction from all your digital sources ? how is that possible ? 😱
😀 seriously. I think that to set up a very good sounding digital rig is not easy at all. Some players are really bad sounding.
I am not saying that is not possible but it is not easy.
If not all this longlasting debate analog vs. digital would not occurr.
Analog is always musical. Digital often is not.
A good test is a cd of some dance music like Bacharach or similar.
With analog the sound flows. With a lot of digital is like an hiccup. Not flowing at all.
I often use this disc for my flowing test ... it can sound very different with different players.
Kind regards, gino
I'm with SY here. I would like a cleaner DAC, but my beresford 7510 either from bluray player or USB-spdif gives me music, wonderful music. The marantz CD80 I had before was showing its age and I gave up on it in the end.
By using equipment that's engineered rather than designed, and by not falling for the story-telling and hype that permeates hobby and fashion audio.
As for analogue and digital, I listen to the music and enjoy that, I find that cassette has the most inferior resolution, dynamic range etc., followed by records, then CDs and finally the best results I find are from streaming my music from a music server (this of course also has the minimum of mechanical systems directly involved in the playback.
I cannot understand where these views of digital come from... Though from recent threads I do think a lot of esoteric audiophillia is stuck in a time warp and anything developed after about 1975 is bad, including SMD based designs. With some basic engineering and work you don't need to go to high end audio to get good results, in fact the upper echelons of audio are probably worse for sound reproduction than a lot of the sensibly engineered middle range stuff.....
in my case if I want good dance music I'll put on a Sasha CD...
