Opinions on Rega Apheta 3 or 2?


I recently got a good deal on a Rega Planar 8 and I'm now looking to outfit it with a cartridge. The guy who sold me the turntable has suggested Clearaudio Charisma v2 or  ZYX R100 Yatra H. Due to Rega not having a VTA adjustment, I'm leaning towards the Apheta line instead. Has anyone had any experience with any of the mentioned cartridges and I'm also welcome to other recommendations. I have a tavish adagio for a phono stage and both my my preamp and amp are tube based.

I have tried the ZYX Bloom III with a Planar 8. Although the sound quality is very good, there is an unacceptable hum (doesn't matter whether the motor is on or off) that I can not resolve. Also (very dry in AZ), on some records, there is an occasional loud static discharge pop (every couple minutes). I have never experienced this with any other table/cartridge combination.
Yatra and others are all discontinued old models, you can check on their site. I think Monster Cable cartridges are better than low range of discontinued ZYX. Nakatsuka-San designed Monster Cable cartridges before he formed ZYX. Regarding ZYX you can seach this forum and you will find why it is a problematic: suspension fails before stylus wear off, sealed cartridge body is a nightmare for re-tippers when you have to replace the cantilever, special construction of the cantilever is also very problematic for re-tippers when you want to glue new stylus. ZYX does not support grey market products, and discontinued models cannot be replaced with new models (if they are not from the official dealer), they do not re-tip/refurbish, they can only replace the whole cartridge, but for crazy price.

There are tons of better cartridges on the market (especially vintage MM,MI or LOMC).
it depends on your budget, some killer MM are under $700 and there are plenty of them NOS, some exceptional MM with exotic materials are under $1.2k and those are simply the best even in comparison to the $3k LOMC

Regarding VTA adjustment, maybe you don’t even need to change anything, it depends on the cartridge, you can figure out when you will screw it in and put the needle on the record. If tonearm is not parallel to the record surface (when the needle is in the groove) then you can add spacer between the cartridge and tonearm. The difference will be very small anyway and that spacer is very thin. Positive VTA is acceptable according to Mr. Van den Hul interview (can;t find the link now) and it can improve high frequency resolution. Negative VTA is probably not acceptable, but it rarely happens. I think you can adjust almost any cartridge on your tonearm with spacers (or without them).

Rega does not made their tonearm exclusively for their own cartridge, most cartridges are standard.

A cartridge with replaceable stylus is what you need, you can experiemnt with different profiles on the same cartridge boby (it must be MM or MI/IM). Grace is the best, because many different styli available, not only original, but also from SoundSmith (direct replacement). I prefer the original for LEVEL II
If you want to have warranty and LOMC - you can go for Yatra why not but better one is not H version. If you have capable phono stage it will be good.
It's interesting cartridge and craftsmanship of ZYX is really good one.

As about shims if you will buy cartridge with advanced profile you have to use shims. Of course as Rega tonearm don't have VTA adjustment it's tricky.
You have definitely talked me off ZYX cartridges. I will look into the other mentions you've laid out.
You could find a better cartridge than Virtuoso MM, mainly because the stylus is Elliptical and cantilever is Aluminum. This combination is nothing special, also the generator of Virtuoso is Audio-Technica (OEM). However, having the best cantilever and best stylus profile together can be very costly, but well worth it in my opinion. 

So i could highly recommend you MM cartridges with Boron Pipe cantilever like SONY XL-50, great vintage MM for reasonable price, Boron Pipe cantilever is very rare option, none of the modern cartridges have this option.  A tip mounting hole made using a laser beam.

From Technics research:  "Somewhere in the high frequencies, every cartridge has an undesirable resonance point. Undesirable because there the frequency response curve climbs a sudden peak. If that peak is in the audible range, your records sound not as intended. That resonance frequency is determined by the total effective moving mass of the vibrating system - the summed masses of the diamond stylus and, most importantly, the cantilever and magnet, etc. To shift that harmful resonance frequency up into the high supersonics, the effective moving mass must be reduced to the lowest possible minimum. Also, too much effective moving mass increases the mechanical impedance, thereby negatively affecting the cartridge's tracing ability."

Another example is Grace LEVEL II BR/MR with Boron Pipe cantilever as you can see on my image, but this one have Micro Ridge stylus tip (one of the best profiles with long life up to 2000 hrs). There is a cheaper Ruby version of the stylus. Look at the Grace Level II cartridge. I love Grace, collect them, got some spares of the rarest models. 

If you like ZYX you'd better look for ZYX owner design from the past, it is interesting that Nakatsuka-San designed ADC TRX Induced Magnet cartridges for American brand ADC after ADC original owner and designer left the company. Nakatsuka-San designed TRX series, the reclacaebla stylus screwed to the cartridge body, look at Sapprire Cantilever and VITAL III diamond. Induced Magnet (or Moving Iron) cartridges are heavily promoted by SoundSmith today if you will watch his lectures. 

Stanton collector's series 100 is another gem, CS-100 with Stereohedron II stylus is amazing! Cantilever is sapphire coated (like no other model from Stanton). This cartridge is better than 981 series! Slightly cheaper alternatives: Pickering XSV30o0sp or XSV4000 with Stereohedron tip. Stanton/Pickering is another brands that i collect (all top models), the sound is so sweet. 

All mentioned cartridges are as good or even better than most of my LOMC




I'm not married to MC. I currently have a Clearaudio Virtuoso (MM) which I actually like. I'm open to any cartridge that can bring out the best in the new TT. That said, I'm also curious about MC because I have never used one.
Why do you want an MC cartridge? 
Owned several very expensive ZYX like Airy III and Premium 4D i ended up with MM and MI cartridges and with your tonearm/turntable it can be better. The problem with ZYX is retip, cartridge has sealed boby. My advice is to stay away from the ZYX, there are better MC if you looking for MC only. 
Glad to hear, that third party options are great. There is a pretty good deal on a slightly used ZYX R100 and I might go with that. I also saw on the Rega website that they discourage shims and VTA adjustments don't make that much of a difference.   
I am running an Apheta 2 on an RP10 and it's very good but if I weren't buying one at a discount with the player I'd buy something else.

Lyra or Dynavector at similar price points will best the Apheta - I was running a Lyra Delos prior to the Apheta and it worked amazingly well.  I would highly recommend trying one if it's within in your budget constraints.
You can purchase shims/spacers for Rega tables that assist in changing VTA.  I have two P9's with Ortofon MC cartridges and use Acoustic Signature spacers with good results.
