Product
Overview
The
HIFIMAN
EFlOO
is
a
powerful
hybrid
headphone
amplifier
and
integrated
amplifier.
Housed
in
its
compact
chassis lie
three
independent
amplifier
sections:
a
vacuum
tube
input
stage
works
as a
shared
preamp,
a Class
AB
headphone
amplifier,
and
a Class T
speaker
power
amplifier.
Benefitting
from
vacuum
tube
technology,
both
headphone
amplifier
and
power
amplifi-
er
sound
warm,
smooth,
detailed
and
musical.
Working
as an
hybrid
headphone
amplifier,
EFlOO
can
produce
a
2w
output
under
a 32
ohm
load
so
it
can
easily
drive
many
high
perfor-
mance
headphones.
In
addition,
EFlOO
can
also
serve
as a
hybrid
power
amplifier
to
drive
speakers
of
moderate
to
high
efficiency.
In
power
amplifier
mode,
the
amplifier
output
line
is
fully
independent
from
the
digital
amplifier
line
used
in
the
headphone
amplifier.
