The Truth and Fairy Tales of S\NR in Phono preamps (with multilanguage subtitles)

I read this:
Interesting in this system is the presence of a nearly ideal noise reducer which cleans up LP surface noise along with the preamplifier's input 47kOhm thermal noise.
This circuit is very effective in reducing both vinyl and cassette tape noise

If this estimate is right, means this, not the SNR from the phono/RIAA preamp itself (i. e. without playing records) is important in real live for listening by record player.
