I'm curious if anyone has ever experimented with making an analog to analog cut from a vinyl source without passing the source signal through a preamp (and back again) -- just keeping the RIAA curve of the original and cutting that signal straight into another disc.
I hope this isn't a stupid idea, but I was imagining it would be the 'purest' way to make an analog copy from a disc, just to avoid both the digital stage and additional processing.
I don't have the capacity to do this, but I'd love to know if it could work, and if the results would distinguish themselves from a more conventional approach.

it can be done
but...
all cartridges sound different.
all inner tonearm wires sound different.
all mic-pres sound different.
all turntables have pitch drift.
pitch drift is accumulative,
Playback + Recording + Playback = 3x times more Pitch Drift.
if done with 3x Stock/unmoddified Technics SL-1200MK2-A
will be a total of... 60cents up to 75cents = too much Pitch Drift.
if done with 3x heavy moddified Technics = 15cents = acceptable.
the only risk is that playback turntable can skip.
i want to try the ART MPA 2.
or the Gordon Mic pre...
Mic-Pres probably must be moddified to have 47kohms inputs.
there are "3x Phono Pres" that does not have RIAA... "Flat"

Trust Our Mike to find this, Hey, Not as good as the Vinyl burner though
Congratulations to Rane for seeing this
This is a product so extraordinary that if it didn’t exist, no one would miss it.
A full-function ecstasy generator controlled by a rotary knob on the front panel, as well as side-by-side Power and Glory switches.
There really is nothing like it.
Oh, by the way, April Fool!
Cheers
