i am thinking the zen triode ia se 23 I.2 will match up nicely with my klipsch la scala II's. has anyone tried this yet. i also might hook it
up to my heresy III's. input would be appreciated.

Another thought...the Klipsch lend themselves to passive bi-amping very well.  You could get away with one of the less powerful offerings if they're only for the mids and highs.  Same applies for fully active, but that's kind of a PIA to dial in and requires more kit.

'Scalas are super fun.  I only wish they fit in my house.

Since two days I can tell you that in my opinion the La Scala's and the ZEN amp are a very good match.
Indeed there is a small hum when standing in front of the speakers [not beeing the result of external influence, but the simple combination of this amp with these 104Db efficient speakers].
My room is not big; the distance between speakers and listening seat is only about 4 metres but over there the hum is only faintly heard when music is not playing. It is a minor fact which does not keep me from beeing "grabbed" by the music every time. If you're further away from your LS's while listening ,you should have no problems with that; only with getting yourself out of your chair while listening late at night and going to bed.....
