Get a better cartridge,it’s the most critical to sound quality.
Getting a better cartridge is always a great idea, but respectfully, I cannot agree with the above statement.
The turntable and arm are far more important than the cartridge, IMHO.
This hierarchy was highlighted recently during a series of turntable and arm upgrades on our own deck.
Prior to any upgrades, we gave our reference SHELTER cartridge a rest, and installed a far cheaper DENON MC with a similar type of stylus tip.
Initially, the DENON was a BIG downgrade. I almost felt like trashing it, it was so bad, by comparison.
Nevertheless, I pressed-on and persevered with the DENON and allowed it to run-in over a period of weeks, playing many hours each day. Once we had the DENON run-in and dialled-in correctly - alignment, VTA, VTF, gain, load - it was still a big disappointment.
All turntable upgrades were then made step by step, with days of critical listening following each change. Upgrades included bearing upgrade, sub-chassis upgrade and finally, a tonearm upgrade.
Here's the kicker: The cheap DENON remains on the upgraded deck, and (now) completely out-classes the sound we previously got from the same (non-upgraded) deck, using the far superior SHELTER cartridge. The sound we get now - with the DENON - is in a whole different class. Not just different. Not just a little bit better. LP playback has been utterly transformed!
Unbelievably, the humble DENON took the lead after just the first upgrade and simply continued to leap further forward with each subsequent upgrade. Amazing!
In fact, the DENON now sounds so damned good, I am feeling no real longing to return to the SHELTER. Obviously, the time will come, when I re-mount the SHELTER and hear what it can do on the upgraded deck. (I will report…)
Moral of the story: IMHO,
provided the cartridge is not junk, all components around the cartridge are more important to good sound, than the cartridge itself. I would include the phono preamp - offering the correct gain and loading settings - in this statement.
Just think on it for a moment. The turntable must rotate at exactly the right speed - constantly, ensuring zero lateral platter tilt and zero unwanted vibration - all the while bonding perfectly to the moving tonearm without distortion or vibration, in order to hold the cartridge in exactly the right place, on exactly the right angle, at all times. Quite an ask!
It is my view that the better the cartridge, the more tolerant it is of turntable and tonearm shortcomings. That said, get the turntable and tonearm performing idyllically and even modest cartridges will perform magnificently - easily outperforming the exotica - as we have seen with the low-cost DENON.
Just my 10-cents worth, following months of careful upgrades and hours of listening.
On this basis, my advice to the OP is to retain the current cartridge as a reference point and focus energies and investment on turntable and tonearm upgrades; the turntable and its suitable support, being the absolute priority.
