Dealer hat resurrected, going on and hope you don't miond the below---------
Having a turntable plonked on the cabinet and right next to a speaker of all things isn't a good move in my book. I don't care what the blasted deck is, but being the vibration-reading machine that the pickup is, once this holiday madness is over, I'd respectfully ask you to do the utmost in isolating the thing from its surroundings. maybe a sorbothane sheet or 'boots' is enough, removing the lid-cum-soundboard when playing might help (applies to all decks really, especially ones where the hinges are affixed to the solid-plinth deck-plate)
I only nag on with the above, as otherwise, you may as well have bought a £250 ProJect or AT look-alike, or a Rega Planar 1 with Carbon Pro elliptical stylus, all equally siting-critical. I love the SL100-1500 'vibe' and the arm also looks neat and not as garish to me, so in my very clumsy way, I'm trying to get you to set it up as best as you can for isolation for best sound quality.
The Ortofon pickup may not be made now, but I remember the X series of MCs as a bit 'wild' but not terminally so and actually, well suited to many pressings of yore. i can't find the video now, but there was one which compared the Rega 3 to the then new RP6 using one of these pickups and even on the YouTube codec, there was a repeatable difference, the '3' sounding more 'mechanical' (not like 'digital' was supposed to sound) and the heavy-platter and properly supplied '6' model, more able in the bass I felt.
