Hi Rwd: I think that is not a very good idea to buy the phono preamp that Topoxforddoc told you. I explain why:
- first: both units ( Comet and meteor ) are an outboard phono stage, so the signal has to goes trough additionals cables and connectors that degraded the critical signal that comes from your MC cartridge. - Second: Both units use ( internally ) transformers for achieve the gain for a MC cartridges, so here the signal again has to be degraded for many meters of wire in the transformer where the signal has to goes and- Third ( not last ): maybe the most critical issue in the analog sound reproduction: the RIAA frecuency response of those units; a good phono preamp design ( with a good execution of that design ) has to have a RIAA frecuency response of at least: +,- 0.1 db from
20Hz to 20,000 Khz. Those units has a deviation of ten times ( 1 db at 20Hz ) over this RIAA response, this number is by a high-end standard: inaceptable.
Once ( maybe still today ) the Vendetta Research was the standard, it has a RIAA frecuency response deviation from 20Hz to 20,000 Khz of only: 0.05 db, I think the FM Acoustic preamp meets this number, too. I'm not a man of electronic specifications but in the phono stage the RIAA frecuency response is extremly critical and no one has to leave " pass-on ".
BTW, I give you my advice: first change your phono cartridge ( trying to match with your tonearm ) for a better one and a second step will be to change your preamp for a new one that has a high gain ( depends of the phono cartridge ) buil-in phono stage ( with out transformers ).
Regards and always enjoy the music.
