can be fooled when blindly comparing a vinyl deck direct output to an additional ADC>DAC stage. So it's good to know that it could theoritically do some things better than the CD, but it all goes up in smoke when you barely have 60dB of SNR and 2.5% THD: http://www.tdkperformance.com/PageFiles/1058/TDK%20Turntable%20USB%20specsheet.pdf
While that would be a representative set of figures for an early 70s budget TT it is a little unfair, common Sansui, Denon and Technics TTs of the late 70s/early 80s regularly managed SNRs of better than 70db some managed over 80db - however the medium itself brings the average back down - Ben Bauer did some AES papers on the limits of LPs and he was getting about 62db but this was back in the 60s , iirc a very good half-speed mastered LP may get to about 82db or so
Surely a laser deck will provide much better measurements, but we're not in the consumer market anymore.
Play vinyl through a tube amp and you're looking at ±5% THD?
