Welcome Steve. Nice to have you on board.
I have read glowing reviews of your products on other forums.
I do wonder what you expect to come out of Amir’s measurements.
As I see it, there are 3 possible outcomes.
1. The measurements show no effect at all
This depends on the measurement method. If only using a DAC to look at jitter, then he is using the wrong DAC. I requested that he use a DAC with resampling on the inputs and one without. I would like to see measurements with and without a DAC.
The other issue is relative scale of the jitter. If one believes that very small differences in jitter are inaudible, then the wrong conclusion may be reached. Like I said previously, a small change in jitter, from 22psec to 7psec was immediately obvious to me using my system and in my measurements. If the playback system used is not resolving enough or the noise level too high, then these differences may not be audible.
2. Your device degrades the measurements.
That would be a shocker. Given that this is my most popular product in 22 years and I have never had ANY negative review, I would have to blame the measurement system or techniques for not correlating to the audio result. My re-clocker outputs very fast edges, around 400 psec. This is why I usually insist on using my 16GHz aerospace quality silver cable from the output to the termination. If the measurement system cannot properly terminate to a signal this fast, it may cause problems in the measurement. The AP system is the world standard, so I believe this is unlikely.
3. Your device improves the measurements.
I would expect this, although I am frankly dubious about the measurement technique. I did notice that my measurements on the iFi SPDIF iPurifier correlate pretty closely with Amir's, so that is reassuring:
