Hi Tony,
Unless you`re just determined to blow out your ear drums I`ve felt that with your very efficient Zu speakers the Frankenstein would provide all the high volume one could want. My speakers are 94db(4 to 5 db less than yours) and in my resonably large space I can produce more sound pressure than I`ll ever need. In fact I`m having the gain in my Statement linestage reduced by Israel as 20db is far more than my system needs. Lastly tony, welcome to the Frankenstein owner club
