Pleiades (R,ωL) filter vs 2 omni mics out of phase part 2

(Later addition: there is a mistake in this post, the AKG D190 used seems to be a D190ER version with internal low cut).


There may had been systematic errors on part 1.
One of them is listening with headphones sending sound to one ear as Sony TC-D5 Pro II was used instead of Pro (I) which has a mono switchable mode.


After listening again with Vicky on her hi-fi system, the Pleiades filter seems to win and the first 3 used mics sound the best on the particular male singing voice.


Signal path:


TDK SAX type II cassette recorded on part 1 - Pioneer CT-443 cassette deck - Musical Fidelity Synthesis amplifier - Spendor Audio Systems SP1 speakers


AKG D190E with Pleiades (130Ω,ω40mHΩ)
Great smooth sound


Fostex M80RP with same Pleiades filter
Lower volume, great sound and as Vicky mentioned sentimental detail or sensitivity, it demonstrates how the singer feels


Shure VP64
Nice big sound


Shure SM63
Spitty, excessive mouth noises etc


Beyer M55
Vicky mentioned high frequency peak problem on both Pleiades filter setup or 2 omni out of phase setup


2x Beyer M55 out of phase
Vicky mentioned lack of bass
(perhaps mics were used 2 close to each other canceling more LF content than needed


M55 without Pleiades (R,L) gentle slope high pass filter
Vicky mentioned how unrealistic it sounds, like an amateur recording
