Cartridge mounting


A local dealer has mounted a Grado Red cartridge on my Thorens table with Rega RB303 tonearm but mounted it with the screws upside down.  I assume it's much easier to do it this way, but aesthetically I don't like the way it looks.  Is it unreasonable to expect with a Rega tonearm that the screws go the other way around?  Thanks for your comments.

Dear @lou_setriodes

Your bad experiences with him aside (sorry about that), he may actually have experienced a setup he prefers by orienting the screw head on the underside of the cartridge.

It may well be for example that in doing so, he torques the screws differently than when mounting the screws right-side up.  Small differences matter, and this is but one reason for him truly preferring mounting this way.

Thanks everyone for your comments.  Next time around, I will definitely learn how to do this for myself.  This was part of a bad experience with a local dealer.  I don't really want to go into details or slam him publicly but he was less than honest in his dealings with me, installed a cartridge that I never authorized him to do and ruined the cartridge that I brought to him to install for me because he really wanted to sell me one of his cartridges, than lied to me and told me the cartridge I brought to him was no good with a totally bent cantilever and the magnet missing.  This was a brand new Goldring Elan that a friend sent to me.  I get it, that it might be like putting Formula 1 tires on a Yugo (My TT is a Thorens TD125 mkII) but I didn't feel like spending the money this time of year.  The plan was to listen to it for a few months and then buy a new cartridge, but now I know where I'm not buying it from...... 
Just so pops , just so !
Not to mention that when you check it with a good device at home more often than not you will find it off .
Being a dealer doesn't mean you know what you are doing .
Been there, seen that .
Absolutely, if I can do it you can.  Hard to have to be dependent on someone for a relatively easy job. 
If you want to get vinyl right you need to learn how to do it right yourself .

As is the case with all adjustments:'' it depends''. In this case it

depends from the headshell ''screws accomodation'' and carts

screw holes construction. BTW AT headshells have screw threads

at the under side. So in your terminology in those headshells all

carts must be fastened ''upside down''. There is no ''up'' and ''down''

in absolute sense. Those are our ''mental orientation'' words . But

language and reality are different things.

If it bothers you so much then why don’t you do it? It sure ain't brain surgery!
The dealer told me that this is the better way of mounting the cartridge with the screws upside down 

Better or easier is the question here I think.  How could there possible be any difference sonically whether the screws go one way or another???  Better, because it's easier and probably faster to do it that way and less chance of messing it up, I'd bet......but we never got into that, instead our conversation turned into a yelling match because this was not the original cartridge that I asked him to put on for me.  
Thanks for your input, I just picked it up this afternoon and with so much going on, didn't really notice it until now.  I'll bring it back to the dealer tomorrow.  Thanks again.
I had a grado on a 303 and the screws were right side up. I’d ask the dealer why as it’s really not that difficult to install right side up.
