That looks like it's from the power supply. Get a -160db log spectrum for more detail.
The difference between Opal and Ruby is much much more than that. And then some
OK. I am not trying that hard. The signals are too unpleasant to listen to so there is not much incentive.
IMO, the 19 kHz is of no importance at all. It doesn't make it down the string between my two tin cans. Maybe if I stretch the string tighter?
Unfortunately, if you want a really good listening panel you have to exclude anybody above the age of about 40, because their hearing isn't what it used to be. If you want people with a lot of experience, electronic or musical, you have to exclude anybody below the age of 40. Though I hear plenty of differences, and have a preference, I trust my measurements far more than my hearing.
What the heck is that noise in the files? My worst LP transfers get cleaned up better than that. OTOH, these files seem to have more life or emotion than the earlier test, where I thought all the files were flat in some way.

Hehehe I believe heb1001 on this. I listened the file on very low volume but I could feel it. I wouldn't be able to stand a full volume
How that? You do not hear -65dB 1kHz single tone but you hear -78dB 19kHz totally burried in average music signal.
Firstly. thanks to fas42 for the honest comments on how it sounded (and when I listen I think I prefer Ruby too which shows just how much a part subjectivity plays in what we actually like).... however, are you all ready this....
Ruby was recorded on an original but mint and pristine Sony TCK5 Dolby B cassette deck (from around 1978). Its all discrete and electrically all original. 35 year old caps and all.
Opal was a Sony CPD 790, again unmodified.
Surprised ? or not ?

You don't think there might be some intermodulation distortion from that 19kHz signal in the ADC?

I spent my whole childhood listening to tape and it was much better than that. What went wrong?
Nothing went wrong.
What this kind of test seems to show is that you all look first to software analysis, and then base your listening opinions on the result of that outcome.
That's how it seems to me.
