Testing Pleiades K117 1.3V mic booster preamplifier, Pleiades (74Ω,25mH) filter with low output GR1/L 25/50 Ω ribbon microphone

 At your risk.

Testing while trying to make a piano, vocal demo of the song To Diko Mas S'Agapo - Giorgos Oureilidis.

Signal path:

almost whispering male voice - mic at 24in on stand - Pleiades 8mH:78mH low cut (bass correction) 25ohm to 250ohm autotransformer - Pleiades (74ohm,25mH) low, low mid, mid correction filter - Pleiades K117 1.3V mic booster pre-pre - Sony TC-D5M (preamp with cassette recorder) - TDK SAX type II cassette - Sony TC-D5M used for playback - Pleiades 2N3053 class power amplifier (one channel only) - Celestion Ditton 150 speaker

It sounded impressive with great articulation, no bass heaviness, no hiss

Although high frequency detail is excellent maybe mid is a bit too prominent. Perhaps using a non low cut 1:3 transformer just after the mic and before the filter will solve it.

It would be also great to check this kind of setup on how close it can get to a master vocal recording such as Suzann - Leonard Cohen produced by John Simon.
