Creek Audio has been making headphone amplifiers since 1993 and
therefore understands what is needed to make them sound good. The OBH-21 mk2
is the latest in the long history, being small and very stylish.
Designed to complement the Creek full sized range, it has an impressive
solid aluminium front panel with either a silver or black finish. Its
housed in a custom black metal case is fitted with turned metal disc
feet and sound absorbing cushioned feet.

The OBH-21mk2 is essentially a very high quality miniature integrated
amplifier, designed specifically to drive two pairs of low impedance
headphones simultaneously from a line level source, such as a CD player,
DAC, or amplifier without headphone output. It can even drive demanding
8 Ohm headphone if called upon to do so. Unusually, it is also
designed to act as a single input high quality pre-amplifier, if
required. Its output level is controlled by an ‘audiophile quality’
ALPS 27mm Blue Velvet volume control on the front panel and by user
adjustable gain setting switches on the bottom of the case.
The OBH-21mk2 has three pairs of stereo RCA sockets
on the rear panel for Line level input, looped Line level output, and a
variable pre-amp output, whose gain can be set, independently from the
headphone gain for the greatest flexibility.
OBH Uni Power Supply Adaptor
The OBH-Uni is a multi-region, 24V, 0.5A power supply adaptor.
Creek originally developed this power adaptor to simplify the
requirements for selling OBH products in all countries. However,
extensive listening tests and comparisons proved that this high
efficiency regulated power adaptor can also extract the best performance
from all of Creek’s OBH products. This includes the latest OBH-15mk2
Phono Pre-amp, which has high-gain and is therefore more demanding of
its power supply’s purity.
It is supplied with three different snap-on power-plugs suitable for
Europe, UK and USA. The snap-on head on the latest version of OBH-Uni
uses a 2 pin, figure 8 connector, so it’s possible to use a 2 pin figure
8 extension power cord, with alternative mains plugs on the end. It
provides a stable output from any input mains voltage range from 100 –
