Hey @josh358, wouldn’t it be fascinating to hear the Tympani IVa and MG30.7 side-by-side?! That would take a MIGHTY wide room ;-). As you recently (today?) said over on the Planar Speaker Asylum, the 30.7 can’t be bi-amped, so the T-IVa has that advantage. I think both share the same ribbon tweeter, but the 30.7 has the new Magnepan mid-bass driver.
If I were wealthy, I’d have ’em all: the 30.7, some Sound Labs, Roger Modjeski’s new ESL with his dedicated direct-drive tube amps, the Sanders ESL, new Quads, double (stacked side-by-side) Eminent Technology LFT-8b, and any other planar contender. And a room for each! When I with my sisters watch the HGTV shows, I’m always looking for the room in each house that can accommodate big planars. None of the home buyers mention their need for a "music room", but the guys always want a man cave for a big screen TV. Normal people (non-audiophiles) seem to have lost their interest in surround, though.
