Critical oppositions made using inadequate equipment.

+1 @hilde45 - not enough info to draw conclusions

@surfmuz

critically estimate tt or cartridge characteristics

What does “critically” mean? Hearing any changes? If you mean like a professional reviewer then the entire audio chain must be of high enough quality to hear differences. If the later then the answer is no.

cheap monitor speakers

Also vague. Price is not the same as performance.

In high-end audio, the entire audio chain matters. Often addressing/upgrading the weak link components yields the best sonic upticks.

In order to sonically evaluate an audio component, the rest of the audio chain must be of a high enough quality to hear the differences.  Not enough data to draw any conclusions 

Haha, I use holy water @surfmuz and it change the whole sound (in a good way).

Does it exorcise demonic audio noise?
