Wasn't the statement about a 'huge difference' used simply to make a point? I've certainly not described differences as huge. I'm not sure why a huge difference would be expected from something that is clearly in the diminishing returns territory. It seems a bit of a strawman argument to make.

Corrected.
Now, let's see if you can add to the rest of the forum. Done with the circles.

Sad to relate it is more to do with how much I spent on my stereo than how little I spent on my car, mind you I use my stereo for far more hours than any car and, once happy with it (in the mid 1990s) have changed only to one major item, though that obsoleted 3 others, my old DAC, pre and monoblocs are now in storage.I'm actually surprised to hear this, Frank! Given your professional background, would have thought you'd at least have splashed a bit of money on a car at some pointNot as worthwhile an investment as audio to you over the years?
Did someone give you your Ferrari Frank?
Company car!

Its my grammar and punctuatuon. A damn misery trying to get any of this out on mobile without proof reading.I don't think your double negative expressed what you intended.
I take you to be a pretty smart guy. Maybe you could help me. By what mechanism would something like resampling impart an audible improvement to some of the claims as stated by some proponents of this device? I can't even imagine in theory, let alone technically.
No I bought it new, and it cost less than my stereo would have cost to buy at the time, if I bought it all at once. I am part ashamed and part feeling I had my priorities right.
I have only had a company car a few times Keith. Latterly I negotiated a contract for enough for me to buy what I wanted rather than have somebody else choose but got the company sponsor to pay for fuel.
Thanks for you compliment. To be honest, your question gave me trouble because I skipped most of the uninteresting posts from some uninteresting members, so I have to read them now to see what they were talking about. For this kind of excessive upsampling, if there is an audible effect, it could be higher latency (for interactive use) or more susceptible to clipping if is there is not enough headroom. I am interested to see it measured because the results published on Stereophile are poorer than what I expected, as mentioned here:
https://www.audiosciencereview.com/...le-review-measurements-also.11868/post-398661
The M-scaler being a digital device there is scarcely anything that can be measured. The impulse response is readily captured, and that's that. A few sanity checks (level changes, clipping, dither characteristics) might be prudent, but I wouldn't expect to find anything too horrifying. After all, Chord products tend to be over-engineered to the point of absurdity.
Resampling ahead of the DAC can potentially be beneficial if the in-DAC processing is poor, especially at 44/48 kHz. Otherwise it is quite pointless. Again, I'd expect a Chord DAC to perform perfectly well without the need for such crutches.
Sure, I don't expect it can have any severe issue but for example this one:
Something like sox rate -v is already better than this, right? Not an audible concern but why? Chord specs say it uses Xilinx XC7A200T, did a quick search on the Xilinx website I found this:
...Then I found an XC7A25T on a new RME HDSPe AIO Pro
https://www.sweetwater.com/store/de...-pro-multi-format-pci-express-audio-interface
So looks like much slower but this card can run TotalMix FX with tons of channels.
Also Apollo X16:
So XC7A200T should be pretty high-end right? I don't understand why artifacts at -140dB, again not about audibility, but why.
Wow, how come that doesn't make Mr Watts' ears bleed? Those spikes are (at least) 160 dB above his hearing threshold.Sure, I don't expect it can have any severe issue but for example this one:
Considerably.
