ARSCers,

Building on the Great 78 Project <https://great78.archive.org>, the
Internet Archive <https://archive.org/details/archive.org> is working
towards a new project to digitize LPs. Dubbed “Lost Vinyl”, the project
seeks to preserve LPs focusing on those that never made it to the
digital world.

We are seeking community feedback to help us find the best sounding
recording chain.

In this item ( https://archive.org/details/lostvinylsamples ) you will
find 5 sets of LP transfers of 5 very different musical styles done with
4 combinations of phono-preamp and analog to digital converter. The
components cost anywhere from a few hundred dollars to several thousand
dollars. The demo files were prepared by the technical engineering staff
at George Blood LP <https://www.georgeblood.com>. Performance
specifications were verified (all RIAA preamps are within 2dB of each
other at any frequency, most within 0.1 or 0.5 dB), levels were matched
at each stage, and all are recorded at 96/24. The files have been
renamed in different orders to obscure their provenance. Only one person
has the key to which file was made with which combination of hardware.

The hardware used includes:
RDL (Radio Design Labs) EZ-PH1 phono preamp
TimeStep phono preamp
Focusrite Scarlette A/D covertor
Prism Lyra A/D convertor

The combinations are (in no particular order):
RDL into Lyra
RDL into Scarlette
TimeStep into Lyra
Lyra standalone (using instrument input terminated by 47 kOhms resistor
with RIAA EQ preset)

Please add your comments in the reviews of the item containing the
samples https://archive.org/details/lostvinylsamples.    
To reiterate-- the samples are made with different equipment and are not
consistent from one work to the next.

Thank you for helping!   If you would to participate in other ways,
please let us know.
