Hey Dev.
Sounds like a great system and good priorities. I also prefer higher sensitivity speakers although I havent gotten as high as you.
I had the Kaguras at home recently. Bottom line is that they need tweaking and time to get to perform but my reaction was that I prefer the wavacs. They are more dynamic. The Kaguras maybe had slightly more resolution and equal liquidity but what I love about the big wavacs is that they do offer the many benefits of SETs but also are very powerful and dynamic by comparison. This doesnt make the Kaguras bad, they sounded great in Munich above a certain frequency (I am guessing 300hz) but below that they are challenged and therefore the wavac offers a better high end package.
This is MIchael by the way, for some reason my Mihalis account isnt recognised or locked by Audiogon.
