Does someone’s opinion affect your opinion?

So I have a very nice turntable with a new MC cartridge which I liked and enjoyed…that is until someone said that the cartridge was very “piercing” and in his opinion almost unlistenable. Now I find I am not enjoying it as much. Two things to add, he is not anymore “golden ear” than me, and the brands are well known with good reviews. 
But now, I don’t enjoy it as much. I know I shouldn’t let it bother me, but it does and it has impacted my enjoyment.

So, has this happen to you and what did you do? 


How a cart works in one system can have very little relevance how it’ll perform in another. There are a bunch of variables that impact how a cart sounds. The loading from the phono stage, cables, tonearm compatibility, VTA, SRA, VTF, different system synergy, room effects, etc.  It's possible to get some direction from others, and even some point of reference by listening to their system (if it's good), but in the end you really need to go your own way and piece together things YOU like on your system.
