I'll second that welcome to AudioKarma,
@santtt! Let's slow down a bit here, shall we, and first off do a thorough check of your Stanton, a worthy cartridge, to include cleaning the stylus (which I trust you have already done, but dip it into some blutak to make sure you have everything off of there), followed by a careful check of all the setup parameters, including VTF, VTA, zenith, and azimuth. If you are not familiar with these terms, you will be well-served to learn about them and there are many threads here that deal with each. Then, let's remove the little wires on the rear of the cartridge and use some Deoxit D5 to remove any tarnishing (oxidation) that might have occurred there creating the imbalance of sound you mention. Again, there are threads here that will help you with this, being careful not to damage either the wires, the clips, or the posts in the back of the cartridge. Then, clean your RCA connectors from the turntable to your phonostage and also those from the phonostage to your receiver. Now you're hitting on all cylinders if you have done things properly and only then can you make an informed decision about whether or not to keep the cartridge. By the way, that Stanton is a far nicer-sounding cartridge to my ears than the Ortofon Red......not even close, and the Ortofon Blue might get you closer but I really think you will benefit by doing some work with your present, very appreciable setup! Good to meet you, amigo, and I trust you will be happy with your time here......carry on
