Phono stage and cartridge

I have been in this hobby for 40+ years and am always on the lookout for better recordings. Focus your search this way rather than on the "flavor of the month" component! Your present system is fine enough as is and quite revealing of recording SQ! No need to be neurotic and worrying about changing components! Just buy better recordings! 

 No need to be neurotic and worrying about changing components!

Room treatments are often the last to be considered but one 
addition that can make the most substantial benefit.

Without them I liken it to chasing ones tail.

Tend to basics mate. Is you phono cartridge aligned properly? Is your tracking to light or too heavy? Is everything "tight" on your rig (screws that attach cart to tonearm, anything loose that shouldn't be)? Do you use any isolation under your turntable (got to keep things from vibrating)? Do you use a power conditioner? Are your interconnects shielded (important if you are near industry or military)?

A stated above, it's important to have reference recordings that will tell you when your system is misbehaving.

Finally, Although often ridiculed, the accessories in this hobby usually serve some purpose.

While cartridges an phono stages can make a big difference. That difference is subtle after a point of quality. While I am not familiar (never heard) with your phono and cart, I doubt they are your issue. I would suggest you check your cart set up. I use "best tractor" specific for my arm and table. A two channel music purpose system, does not need subs. Subs are for action movies. A good set of full range speakers will give you what the music requires. Unless you are looking for an exaggerated sound. As far as vinyl goes. It is true there are better recordings then others. But bad recordings are not the norm. They are the rare. Fantastic recording are more common. Not the majority. What you describe are awful recordings. If this is what you are consistently hearing, I would check your cart set up. I would inspect the cart as well. Get a good test record and check your set up with that. Or, try almost any "Dire Straits" album. If they don't sound good, you have an issue. 🖖✌️

Echoing @whatthe in my experience 99% of recordings will sound excellent if your system is working properly (presuming the LPs haven’t been damaged). 

However optimizing  vinyl playback is a painstaking and complex endeavor 

based on your system and my experience with the Wand I would suggest checking

1. Alignment of the arm and cartridge - is it all perfectly aligned using the steel alignment tool that came with the arm? Have you tried adjusting VTA, presumably you have it level at present, and what are you using to measure VTF?
2. Making sure that the unipivot is not fouling, a harsh sound is often the result of a unipivot being off center or catching, it’s hard to get the Wand off center but the edges of the pivot housing can catch, also you may need to renew the grease
3. Gain matching - what gain setting do you have the GCPH (I think this is what you have) on as it’s got a lot of options and you could be overloading the preamp

only once you’ve optimized everything you own would I think about changes

finally if you can let us know which LPs are giving you issues that would also be helpful
