Poor sounding analog?

The Elys is a pretty disappointing cartridge. The Rega Exact is much better sounding. You may want to make sure the phono stage is on the MM setting, and if there is adjustable loading that it is set to 47k.

After looking at the manual for your preamp, it looks like there is a separate input for MM and MC cartridges. Make sure you have your tonearm wires plugged into the MM input. There is some adjustment for capacitance on the MM input. Try messing with that. It may help.

Suffice to say that if your LPs do not compete with your digital, something is amiss, assuming the LPs were of good quality to begin with; not necessarily perfect, just good should at least equal or beat your digital sources.

The Elys 2 is not a great cartridge, having owned one. But it does need break-in time and typically will sound very open and bright. The RP3 is an easy setup, so I would agree with the others to check the preamp settings; MM at 47K and capacitance between 100 and 300pF.

BTW, is your tonearm parallel to the record when playing?

Sarcher is correct. Verify that you have the table connected to the MM phono input and that you have set the correct capacitance for the tonearm/cartridge combo. Impedance on the MM input is fixed at 47K ohms.

My C2300 sounded magical with even with my antique Pioneer PL15D / Ortofon 2M Red right out of the box. It only got better with break-in and was immediately equal or superior to digital sources.

If you still have concerns after checking connections and preamp trim, then it's time for a chat with the turntable vendor regarding cartridge set-up and / or a possible warranty claim.
