"the best sounding recording chain" is, one assumes one with fidelity,
which neither adds to, nor takes away from the original input. That is very
easy to achieve these days, at least with RIAA preamps and A/D converters.
We can even bypass the RIAA stage, doing it later digitally.
Even moderately priced A/D converters these days are more than up to this
task. It should be a walk in the park, comparatively speaking. The
overwhelming weak links in the chain will be in the analog domain, namely,
the inherent limitations of the analog vinyl disc itself, its condition, how
well it is cleaned and how well it is played. The other weak link is the
skill of the person doing the work. A sufficiently competent person knows
his tools, how to achieve the best results with them and just gets on with
I dont understand the reason for this survey. My 2 cents' worth.

Subject: [ARSCLIST] help us select A/D and phono preamp for an upcoming LP
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
We are seeking community feedback to help us find the best sounding
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)

To reiterate-- the samples are made with different equipment and are not
consistent from one work to the next.
