Pro-Ject RPM 3 Carbon Manual Belt Drive Turntable w/ Curved Tonearm & Sumiko Moonstone MM Cartridge

Now it’s time for the heavy lifting. The motor alone weighs in at over 5lbs. This massive AC motor sits to the side of the table, providing complete isolation, and has a pulley for the belt that is machined to .0005% tolerance to achieve perfect speed. If you find the motor heavy, wait until you pick up the platter. This 20lb. beast is made out of aluminum and damping materials. It’s 39” circumference is machined to a +/- .001” tolerance. Coupled to the hardened steel bearing, this system spins at a perfectly constant speed. We believe this characteristic is essential when trying to achieve the “live” feeling from music. If the speed is off, the music does not sound realistic. VPI’s method of mass is one of the best ways to accomplish this since the heavy platter will maintain consistency once it gets up to speed. The first time you flip the switch on the motor, you’ll hear it squelch as it torques up, but don’t let this worry you. While it sounds a bit odd, it’s normal. The Prime’s 10” 3D tonearm is quite a feat. Ideally, a tonearm would be one single piece of material, yet until 3D printing, this has been almost impossible to manufacture. VPI was able to use anti-resonant materials, and the end result is an elegant one-piece tonearm. The tonearm is a unipivot type, meaning it’s free to move around in all directions and only has one bearing. Many in the audio industry believe this is the most friction-free bearing around, allowing your phono cartridge to do its job. The unipivot bearing even has two side outriggers to fine tune its level position. VPI includes a 6” lightweight rod you rest in a groove on the top of the headshell section, allowing you to easily determine whether its level. Another impressive tonearm feature is its fully adjustable VTA (vertical tracking angle), which allows you to move the tonearm in order to align the top of the phono cartridge parallel to the record surface in order to achieve the best possible sound. With most tonearms, this is done by loosening screws in the side or base to raise or lower the arm, which makes it difficult to fine-tune the height. With the VPI arm, however, you simply loosen up two large screws, then use a large round knob to move the height up or down in small increments. Just as coffee fanatics experiment with achieving the perfect grind, VTA allows audio fanatics to experiment with achieving the perfect sound. There is even the option to make minor adjustments based on the thickness of your vinyl records, and the arm has a scale so you can record the exact setting for each record. Finally, to couple the record better to the damped platter, VTA includes a stainless steel and delrin record clamp, which simply drops down over the center spindle to hold down the record. At Audio Advice, we’re very particular about cables included with turntables. Since the signal coming out of your phono cartridge is extremely low in output, it’s necessary to use a higher-end set of cables so nothing is lost in the transfer of the signal from your turntable to the phono preamp. The Prime does not come with cables, which we actually prefer, since it allows you to choose from any of the aftermarket cables on the market today. Your choices are unlimited and whatever model you select will fit firmly onto the high-end RCA jacks found on the back of your Prime table. One final word of advice: you must ensure your Prime is set up by a professional. They can mount and align the cartridge perfectly, and should also preset the VTA to the right height for an average record. From there, all you need to do is put it back together and set the recommended tracking force.

Performance

To check out the Prime, we used it with the Soundsmith Zephyr MIMC cartridge. Like VPI, Soundsmith has been around for over 30 years and is actually made in the USA right down the road from VPI in Peekskill, NY. This is a $1,749 low output moving iron cartridge. The Zephyr was very easy to get setup properly with it’s square body. It also has very good channel separation. One of our favorite test LPs is Cat Stevens Tea for the Tillerman and the Prime perfectly captures his somewhat gravelly voice. The first cut, “Where Do the Children Play,” has a variety of sounds and rhythm changes that are a noteworthy test for a high-end turntable. In the first 5 seconds, you can tell the Prime is special. we’ve never heard bass notes reach down so low while maintaining such a realistic tonal quality. This same track has some very close mic’d guitar lines throughout the song. There are actually two guitars playing which on some rigs is hard to distinguish. Not so on the Prime! They each stand out alone even when things really build up towards the end of the track. The 3D arm really lets your phono cartridge do its job, too. Once everything was set up we were not able to detect a shred of cartridge mistracking. In terms of dynamics, the percussion sounds explode to life with the Prime. After critically listening to a few more tracks, we ended up turning off the lights and putting on an old favorite, the first Chicago Album, CTA. We were instantly immersed in the music. The 3D representation afforded by the Prime is almost spooky. As we played more records, we found the presentation of the music on almost every recording was extending wider left to right than our speakers. We believe part of this is the outstanding audio quality of the Zephyr MIMC, but if the table and tonearm are not going a great job, you would never get that type of soundstage. The Zephyr is certainly a great match for this outstanding turntable. The combination produced deep rich bass, with a high-end extension that was never harsh -- always smooth and liquid.

Overall Recommendation

Listening to vinyl is a hobby full of fun and experimentation. If you want to dive deeper into this fun arena or are looking for a great table to jump in with, we think the VPI Prime is an amazing choice. To set it up right, you’ll probably be in the $5,500+ price range by the time you get an appropriate cartridge and set of phono cables, but we don’t know of another table offering more for the money. If you enjoy tinkering, you will absolutely love the adjustable vertical tracking angle.

The design is carefully tuned to offer the most critical features for the best price and everything is put together with Pro-Ject‘s decade long experience in making the best performing turntables without blowing the budget: MDF is 2-3 times more expensive than standard particle boards, not to mention a plastic chassis, but sounds and feels way better. The X1‘s luxury 8 layers of painting and the hand-polished finish are 3-4 times more expensive than simple foils. Inside, it houses a sophisticated DC/AC generator board which, combined with the convenient speed control board, delivers clean and stable power to the quiet-running motor. This adds additional cost but performs many times better than a simple, direct powered AC motor. For even further improved performance, the motor is decoupled from the main plinth using a new motor suspension system. In the X1, the motor drives a new, heavy, non-resonant Acryl platter via a sub-platter drive system and a premium grade main bearing for liquid smooth rotation. This is the perfect platform on which to place your precious vinyl records, guaranteeing absolute reliability in its performance and sonic character. The X1 is also better than its predecessors thanks to the super-stiff, perfectly tempered Carbon/Alu sandwich construction tonearm. This new 8.6” tonearm design is incredibly light and stiff, with improved resistance to external interference. Finished as a one-piece, with no resonance-inducing headshell, the X1 can also be set for azimuth and VTA adjustment, offering the flexibility that so many people are asking for, especially in this and even lower price ranges. The tonearm is then supplied with a TPE-damped counterweight, further reducing cartridge-tonearm resonances. Lastly, height-adjustable feet in their Alu/ TPE sandwich construction are a very exclusive but necessary feature to level up the turntable and effectively isolate it from the surface it is place on. The X1 has all the high-end features of modern turntable designs to maximize the music and listening experience. All these features can in fact be done at a reasonable cost. Due to our extensive experience and meticulous manufacturing processes, we put resources, time and effort into giving music lovers the best sound for their money, rather than cutting corners to save on costs. It is a statement and a counterpoint against other upcoming turntable designs, which go the way of offering more features but less performance.
