Some other good capsules are Amplino TM3 or Lundahl LL9206 (http://www.kandkaudio.com/mccartsetup.html).
On the german AAA-Forum was a great talk about auditorium 23 and the Haufe capsules because for some the price of the first was too high related to these built in capsules. Mr. Aschenbrenner's success in Germany (import of Shindo and Verdier and self designed speaker, cables and transformers) created lot of envies, as latin say "nemo profeta in patria!" and that's why he sells in the US very well!

Jensen publishes even a good Moving Coil Cartridges/Transformers Table to select the right step up http://www.jensen-transformers.com/mc.html
