Is it really useless Upscaling 16/44.1 music to 24

Is it really useless Upscaling 16/44.1 music to 24/176.4 or 24/192
In the past I asked this question and from the answers I learned that converting any music from 16/44.1 to higher resolution is just adding bunch of zeros in front. But now I started seeing so many DAC’s up-sampling the music to 24/192 or 24/384, which bring up the question again “Is it really add zero in front of 16/44 or did they figure out how to create a broader spectrum in frequency from 44 khz to 384 khz and how many listeners heard the difference in quality of sound by up converting it? “We are not discussing the HD-Track’s music.”
I read the reviews and saw the picture open DACs. I don’t see much in them other than a high rez sound card. Please correct me if I am wrong.
And finally, In JRiver/Foobar we have an option to up sample the music. Questions are
1) Does up converting makes a difference?
2) What is the difference between $500 or $5000 DAC re-sampling the music verses Foobar or JRiver re-sampling?
3) Can JRiver/Foobar do the same job in re-sampling the music as a DAC does?

Hi Dtc. I believe there is a reclocking oscillator on the ports. I dont use the clock function of the G25U any longer as the clock in my dac is more accurate. I would love to be able to tap a clock output into my squeezebox (nice project to figure out). I cant separate the two functions but the unit itself makes a world of difference.

I think outboard upsmpling/reclocking is key to PC audio. It needs all the help it can get. The G25U brght my PC to levels of my K03.

I listen to tidal and jriver alot and upsample with an esoteric G25 u from 44.1 to 192 so that I give my dac a nice robust 192 signal. It likes that. It plays music better being fed upsampled music. Just the way my K03 is. I have experienced the same with other fine dacs.

I would much rather have the hard wear upsample and not the softwear. JRiver (SOFTWARE) upsampling added noise and distortion, in my rig. I upsample 44.1 TO 196K with an esoteric G25 U and it sounds much better than anything Jriver could upsample in my system. I cannot use JRiver for upampling or dsp. i feel the dsp just tries to compensate for other issues further down the audio chain.

I am running a 10 meter spdif cable from my PC (separate room) into my sound room so the G25U is kind of like a signal amp for me. I guess today, its an upsampler/reclocker in the digital world. Its worked splendidly. I think if I had the puter in the same room (i would blow my brains out) I may feed the hi res signals natively and bypass the g25u but it does a good job with intrnal bypass circuit, stepping put of the way when anything higher than 44.1 comes through it. 44.1 sounds absolutely amazing. Of course there is a variance in quality amongst 44.1 recordings but for the most part 44.1 is imensely enjoyable.

Lewinskih01 - I do mean noise and my puter is very quiet as well. Its also plugged into a power conditioner and APS and sits on a 4 inch maple shade base with the brass points and an isolation brick on top - and I would never let the nasty bugger in my sound room necause of all the emf and other nasties is gives off (not just noise you can hear but noise you cant as well). I have a bathroom right behind my sound room on the other side of a wall - I may drill throyg and put the server in that bathroom (I guess like Hillary) to get it closer and get away from the 10 meter cable but it does suound awesome.
