One thing is that I heard that the Avalons are very sensitive to speaker placement...all speakers are to some extent and the Kharmas benefit too but the Avalons are apparently doubly so.
Avalon vs Kharma
How does the Avalon Eidolon & Opus compare to Kharma 2 & 3 series? The diamond tweeter is out of my price range. Anyone with first hand experience? Thanks
