Didn't see the original image, but the point about the correct reconstruction filter for the sample frequency is that it perfectly fills in the missing information and even extends its output as peaks above and below the sample points - no loss of amplitude even if no samples fall on the peaks of the input signal. It doesn't just interpolate, but 'rings'. A digital oversampling filter can get close to the theoretically perfect filter before the output is finally finished off with some light and simple analogue filtering. As far as I understand it, you can get reasonably close to the Nyquist frequency, say 20 kHz for CD..? And I presume that this performance is verifiable, measurable and backed up with the maths.

CopperTop, Feyz, thanks for that.
You are absolutely correct and even a trivial measurement would show the fallacy of the original statements. Another good example how misunderstanding and ignorance lead to a position that it must be 'bad'.
BTW You didn't mention the anti-aliasing before the ADC which also is *required* for the system to work as advertised.
I can feel another column coming...

Seriously, dude.....
One could write a book on the fundamental flaws and nonsense in that article.
Not to mention the blatant commercial interest.

Entirely possible! But I do like the idea that some of the presumed technical weaknesses of vinyl could, in fact, explain why people actually like the sound better than CD - on some recordings at least. It's been one of the talking points in this thread for the last few hundred comments, and we were getting nowhere.
I liked that he had access to the master tape, the LP and the CD and took the time to look into them and their differences. That IS something that's been talked about in this and other threads, but not done.
Not the whole story, but an interesting part, anyway.
Thanks to Coppertop of the link.

Buy our/rent your self a tape recorder and tape a band and make a cd of it and compare as you like.
Can't be to expensive to buy a tape recorder second hand.

Old news for me. I used to own a stable of Revox and Tascam machines, I used them for work. Tape was fun, but not any more.
Still sounds great, tho.
For me the interest lies not in what I can do, but is done in the normal work-flow of the CD and vinyl production. I know that I can make great sounding recordings on open reel, cassette, computer, etc. But what happens to the commercial recordings that don't sound so great?

In commercial recordings there is done some extra tuning I experienced.
I have cd boxes with a song "I need your love so bad" Fleetwood mac, one song sounds really cool and one not, also and both recordings have left and right channel opposite to each other.
I have old 50 and 60 recordings of Stan Gets and other popular music that really sounds fantastic spacious and dynamic only the high-frequent tones are poorer to new stuff.
And 80ties cd boxes I often find horrible sounding seventies are often better.
So how can that 50 and 60 stuff sound so good??
I have some "proprius" recordings that also tries to copy the early one mike recordings.
An externally hosted image should be here but it was not working when we last tested it.

That's one that I like very much myself.
First Impression Music has it on SACD, if you're interested ($25.00).
Antiphone Blues (SACD Stereo)
I believe that Winston Ma used the Original Master Tape on this one as well.

I have recently been admiring Decca recordings of Benjamin Britten from the 60s/70s. It seems as though Decca were rather more than a mere record label. Fascinating article about them in the 70s/80s/90s here:
Decca 1
Not sure it is a good thing to know about the hundreds of edits and total manipulation that went into each recording...

I think the thing I notice most about music from the early Hi Fi days is that it seems to center more upon the emotional presentation quality, as opposed to the "Reality Show" mode of modern day recordings. The latest example of that emotional appeal I have is from Dr Johnson's Reference Recordings released in the HDCD format that he and Rene' Jaeger cooked up.
Perhaps the very best examples I know of from those early days of audiophillia come from the Unicorn studios, the folks who purchased the tube gear from the BBC when they went solid state. Absolutely the finest Mahler I have. The Red Book rendition of the third symphony, while being better at dynamic range, doesn't quite match the emotional splendor of either the tape or LP formats. A technically more complete portrayal, no question about it, but no tears glisten in my eyes from listening to it.
