Phonostage/preamp recommendations. Parasound JC3 Jr.?

Hello all. After searching for hours and not quite understanding if I’m processing the information right, I figured I would sign up ask the question directly with my specific information. Obviously new to home audio so please go easy. I bought a "new to me" Sota Sapphire with a Sumiko Premier FT-3 tonearm and Dynavector DV-10X5 cart. I leveled it out and set up the arm. Hooked it up to my Denon DRA-800H receiver (which says it has a phono input) paired up with Polk RTI A3 bookshelves. Everything "works" fine. Highs are clean and crisp. No funky sounds or anything like that so overall success. My issue comes with the overall loudness of the playback (having to almost max the volume at 70 before achieving listenable levels) and the lack of bass and overall dimension in the music. Not having a sub and understanding they are only bookshelves I don’t expect the world of them but I was thinking it should sound better than my bluetooth Bose Soundlink? Being an MC cart the person a bought the turntable from suggested I could benefit from running a dedicated phonostage before the Denon. The Parasound Jr. looks good giving the option to switch from MM to MC and seems to have a good fanbase.  Am I on the right track to a decent starter system? Any recommendations? looking for something I won’t have to upgrade for a while, but not looking to sell my bike either. Please help school me on this rabbit hole I’ve ventured into! Also not opposed to tubes, but I’m sure that’s a whole other world I shouldn’t be exploring quite yet. Thanks in advance.

Recap on what I have:
Sota Sapphire
Sumiko Premier FT-3
Dynavector DV-10X5
Denon DRA-800h
Polk RTI A3
Well since I already had the zphono in my cart ready to buy that certainly throws a monkey wrench into things....Besides, I don't really want a quicky bandaid to my issue. Having a decent preamp would not only fix my current issue, but also open doors for future exploration with other cartridges. Although if I did go the cartridge route. How would I find the RIGHT cartridge?
Just my thoughts if you go with the PH10 I don't think you will be looking to change or upgrade your phono unit for a VERY long time.
Most of the recommendations in this thread would be fine, enjoy whatever you go with.
No offense to the posters or yourself but your looking at spending a decent amount of cash for used phono preamp when you could secure a nice integrated amp with a built in phono preamp that would be step up in sound quality and also with a built in phono preamp as well...Rogue Audio, Musical Fidelity, Arcam are just a few of the brands out there.
The Dynavector Cartridge is a fantastic Cartridge for the money and a MM phono is all you need as it’s a HO Mc Cartridge....anyone suggesting a step up is giving you the wrong advice and spending $800 plus for a dedicated phono preamp based on your current set up is also wrong advice.  There are plenty of good choices out there used in a $3-500 range for a phono preamp that supports both MM & MC Cartridges that would be a improvement over your built in phono in the Denon.  You need to remember the Denon is built to a price point so you decide where to spend your money. Quality used integrated with built phono for less than 1k used or a more suitable alternative phono preamp based on your current set up and spend $300-500 or even better by a Emotiva XPS-1 for $199 and call it a day.

You may NEVER find the right cartridge, but you will have a lot of fun along the way.

I am advocating MM over MC, and a new cartridge, i.e. new stylus, and HIGH output, for NOW.

Not only solves LP sound right away, it lets you take more time and do more research before you move to new, more important, mpore expensive equipment. And, more time to carefully asses you desired features.

The point of a basic elliptical, high output, is it will be your base for future comparison to future cartridges (returns accepted!).

Keep the existing MC, High Output 2.5mv, it may sound fantastic on eventual new equipment with no need for MC pre-pre stage.

Ortofom 2M Red produces 5.5mv, $100.

excerpt about 2M Red

The Absolute Sound Product of the Year and Editors' Choice Award-Winning Ortofon 2M Red Sets the Standard for Entry-Level High-End Moving-Magnet Phono Cartridges The Ortofon 2M Red MM phono cartridge is as good as audiophile-grade moving-magnet types come at its price point. It features Ortofon's trademark split pole pins, an invention which enables moving-magnet cartridges to have flat frequency response, just like a moving-coil cartridge.   2M Red also uses an improved engine, which provides an increased output of 5.5mV. The 2M Red features a tipped elliptical diamond , engineered for precise and accurate retrieval of the information in the record groove. The Japanese company's 2M series was developed in conjunction with Danish designer Møller Jensen Design. Inspired by the facets of a diamond, whose contours gracefully trace the grooves on a record's surface, 2M 's handsome elegance establishes a great combination of form and functionality. Ortofon' s philosophy is to make cartridges which reproduce the record grooves as accurately as possible, without coloring the sound. The 2M series design has been optimized for ease of mounting and their weight and size fit virtually any current turntable. “[This] is one sophisticated and musical cartridge—for the price of a nice dinner for two.” —Neil Gader, The Absolute Sound , Editors’ Choice Award “If you’re looking for a high-value cartridge…the 2M Red is an excellent place to start.” — Stereophile , Class D Recommended Component “It’s worth experimenting, because at best this is one of the most detailed cartridges we’ve come across at this kind of price.” — Tech Radar “The midrange is full and expressive, handling vocals with sensitivity and warmth. The bass and treble interact well here, and while we'd like more authority from the bass,

You need time to consider whether you will try Tubes, preamp or amp also, another reason to get listening right away with a basic elliptical.

Example I may or may not want an MM cart in the future or a different MC and I would want to buy something now that can accommodate a fairly large variety of options vs something that’s more specific to one type of setup. Buy once cry once if you will...with limitations of course.

FWIW Dept.:

SUTs are not all that specific. They will require loading at the output, depending on the cartridge used and the SUT in use. Jensen transformers makes some of the best for this purpose and also have a pdf on the correct loading for the transformer (assuming also that the input of your Denon is the 47K standard).

However I would have expected a cartridge with 2.5mV to be no worries in this situation- and since you are experiencing weak bass and low output that suggests to me that something is amiss rather than you're actually needing a different phono preamp. I would investigate your tone arm setup first to make sure it really is right! For example the arm height can mess with the bass as can the platter pad itself. I have also seen damaged cartridges where they had low output and no bass because the magnetic motor has been damaged, probably from being dropped. I would exhaust these issues first before buying another phono preamp- if you did buy one and you still had the same problem I'm guessing you would not be happy about that.
