Anybody else into collecting/digitizing large volumes of vinyl from all sorts of strange countries? If so let's talk, my Soulseek username is "freitas62".
Anyone who is serious, I have built a very high quality phono preamp (well-proven prototype) especially for digitizing not only 45's & 33's (which adhere to the RIAA equalization curve), but also 78's (which need compensation, but not as extreme as the later "microgroove" recordings, and there was no standard).
If you could buy one as good I wouldn't have designed mine.
With the right partner, could even be launched as a PONO recorder to complement
the upcoming PONO Player.
