I’ve extensively auditioned a Benz Lukaschek phono stage and a Musical Surroundings Phonomena phono stage in my home system. The Benz Lukaschek was clearly superior to the Phonomena in three dimensional imaging, smoothness, and detail (as it should be at twice the price). The lukaschek is an outstanding phono stage that you may well want to audition since you have a Benz cartridge.
I cannot be sure how much improvement the Lukaschek will offer compared to your Plinius M16 which I have not heard, but I would guess that it may be significant because the Lukaschek will not leave you wanting for much.
I am also shopping for a phono stage and want to hear other contenders before I make my final decision. I’ve researched the internet and understand that the following phono stages, which I have not heard, all offer very good performance:
EAR 834
Acoustech PH –1
Audio Research PH3 and PH3SE
Audiomat Phono 1
BAT VK-P5
BAT VK-P10
Klyne 7PX3.5
Krell KPE and KPE reference
I would appreciate any comments about these phono stages – especially from those who can compare them against each other and against the Lukaschek which is my current reference until I hear better.
My system:
NOS Fidelity Research MC201 cartridge ( 0.12 mv output )
Rega planar 3 turntable ( to be upgraded soon )
Sim Audio Moon I5 amplifier
Spendor SP 1/2 speakers
