Interestingly, the ELP Laser Turntable had one of the flattest
frequency responses I'd ever measured. Far flatter than any
electromechanical cartridge, which is why I think the sound
(harmonics, timbre) of the ELP Laser Turntable is quite accurate.
However, there are other compromises with the Laser Turntable
(like low signal-to-noise ratio) - nothing is perfect.
I have found this to be true, as well. My best disc transfers use the ELP
with custom filters to reproduce the RIAA (or other) curve. The CD vs.
digitally-mastered LP restoration comparisons are very telling. On
occasion, because the ELP is so flat (especially down low), I am forced to
use a high-pass filter on the final file to minimize rumble from the
*cutting* unit.
Sadly, master tapes sometimes go missing and a mint LP may
be the best that's available.
Yes. Also, master tapes can simply degrade to the point that the original
LP sounds better than the digital transfer of a master tape would. Sad,
but true. There are numerous examples in print right now.
