tony -- its both 120 & 220 V
----------------------
and its about time a member asked for the ' 3 grail comparo ' ::
......
for starters -- imvo --there is NOTHING -- no 1 piece // no 3 piece // no 12 piece

that can touch the ultra expansive
high end of an m90 = NOTHING
for looks and overall sound --the 970 is really what a boombox SHOULD look like --
its just so elegant and magificent -- and its sounds very beautiful -
but slightly less great than the m90 and the c84
to my ears --the c84 actually//honestly has a deeper bass than the m90 --its got a more ' kaboomish' bass
in fact - the c84 sounds so good --
that if i had to listen to either box ALL day long --i would not care which of these 2 ...
for pure listening pleasure ... the m90 and the c84 are totally interchangeable
putting my $$ where my words are --
i would trade an m90 to get another c84 .......................... RIGHT NOW !!
anybody ??
