Cartridge upgrade

I wonder why you are especially interested in Kiseki cartridges. Decades ago, the Kiseki brand was a significant player in high end audio and associated maybe with Sugano, who went on to Koetsu fame. I think in recent years the name has been co-opted by a different company and I’ve not seen such glowing reviews of the modern lineup, although they also resurrected some of the names, like Purple Heart, from days of yore. I would stick with more main stream brands, like AT, Ortofon, Dynavector, Soundsmith, Grado, etc, where I think you also will get more for your money. For example, the AT 9Xa and 9Xi cartridges that cost less than $1500 or even the Nagaoka MP500 for a shade under $1K. Or Soundsmith "The Voice" for similar money. Just my two cents. (If you're planning to use a SUT, do some reading before you pair a low output MI cartridge (e.g., SS or Grado) with a SUT.)

@lewm I kind of wanted to grab a Purple Heart as a fellow commentor mentioned Kiseki is pulling out of the US market. I guess I could grab one used somewhere down the line. However, I’m not against buying from Soundsmith or some of the makers that you mentioned. Over Christmas there was a sale on Hana Unami Blue’s. In hindsight I should have grabbed one. I kind of want to shy away from a cartridge that requires a step-up transformer.  My Chinook is the Upscale Audio Ed. that has up to 65 db of gain.  Is that enough?

@rfauto The Voice is $3000 and a great buy. I have heard it up against $10,000 MC cartridges and it more than held its own. Turn the volume all the way up with your preamp on Phono without any music playing. What do you hear? Now turn the volume one third of the way down. That is as loud as you will need to go with the Voice before blowing up your speakers. Hear any hiss? 

@lewm you are not kidding. I tried the Hyperion on my SUT and it was AWFUL. However, rf has a Manley Chinook, so not a problem. Are you still listening to the Nagaoka? I almost went for one, but on a nostalgic lark I picked up two Shure V15 V MR bodies in excellent condition. I'll try a few Jico styluses and sell one.

@rfauto You have a Manley Chinook and can play any cartridge MM, MI or MC without a step up transformer. You are cleared for any cartridge except perhaps the lowest output MCs with outputs below 0.2mv. You could use them but won't have the greatest signal to noise ratio. Moving Iron Cartridges like the Soundsmiths and Grados have one major advantage over other cartridges and that is a much lower effective mass. The moving system of the cartridge is much lighter and can follow the groove more accurately. I would take the Voice over any MC cartridge below the price of $6000. Then there is Soundsmith's customer service and relatively inexpensive rebuild prices. 

Find a gently used Soundsmith cartridge, i got a Carmen II 5 years ago and just had it rebuilt and I'm still way under the price a new one would cost. Soundsmith rebuilds their cartridges for around 20% the cost of a new one and they sound fantastic.
