My experience with the both the Benz and Kiseki is the Kiseki Purpleheart is underwhelming - muddy and not high resolution.
For your budget ( I used to distribute the SME v ) have a look at the van den hul range - they match the 11g effective mass of the SME beautifully with great results in my experience and are much better than the Hana.
Soundsmith MI from the Paua up are also superb - better than the Kiseki for sure. I listened to SS Paua on the SME V for a couple of years - superb combo - better than either Lyra Skala SL or Koetsu Rosewood in the same system.
