Help in deciding between these two cartridges for an upgrade

Thanks for that option, MC

I had been focused on the other two due to the nice deals from Kron here on Agon.  I simply cannot pay retail for most anything, especially high-end audio components.  

After reading Michael's review, I actually stumbled across a unique option to pick up a new Soundsmith Zephyr MIMC for $1400.  I just may go for it!  The rebuild option for $350 really is a nice bonus to essentially have years and years with that design for minimal cost long term.

@drrsutliff  I have not tried arm spacers on my Rega tables.  I have trusted their philosophy that as long as the cartridge body is fairly parallel and the rear is not angled down to actually make contact with the record then you are okay.  Both my Eroica and Benz are taller cartridges compared to the Exact 2 yet have remained in good positions.  As they state, this is a very controversial subject so there may be something to be gained that I am unaware.  Pictures can be deceiving but the Ortofon design does appear rather tall to potentially create the need of an adjustment.  I appreciate that insight regarding the Cadenza.

I am glad you mention the Apheta!  I forgot I actually got a very low hour Apheta 3 with my RP 10. I already had the Benz for several months and was used to that sound and tried  the Apheta. It was very bright to me and I didn’t care for it so sold it while it was still at its peak value to help offset the upgrade of the RP 10. From your experience this would push me towards the Kiseki.

Yep, I am using the integrated's phono section.  I heard the differences/improvements as I climbed the phono ladder to end up at an Audio Research REF Phono 2 prior to getting the GSi75.  I also had a REF 3 and REF 150 to round out that system.  I considered keeping the REF2 Phono but honestly was shocked that I didn't hear much of an improvement compared to the on-board phono.  It still surprises me and I would like another listen, but that is long gone.  I suspect one day I will return to separates but likely several years away.  Trying out another phono would make sense as I would have that head start on the move back to separates.  The REF 2 was gone by the time I got the RP10 + Apheta 3 so only heard that from the on-board phono.

Thanks, I have always heard nice things about those cartridges but they are a stretch.  I mentioned $2k not as a budget but as the MSRP of those I was targeting.  I hadn't considered the AT brand, but will take a closer look.

@verdantaudio

Noise issues are a nightmare...good to know and hopefully that was an isolated issue with that particular cartridge.

@nmmusicman Well, that is a good way for me to redirect my funds to a patio and leave the stereo alone!  You know, I have been having my doubts over the weekend since I did love the move to the Benz.  It was a $1600 cartridge new so I am basically in the same price bracket here.  I understand that a different design could offer someone advantages even at a lower cost and I will never know that until I try something else.  

Thanks everyone for your thoughts.  I learned of a couple more nice options here from your input so now it is on me to decide.
