HeadRoom’s ‘Max’ Electronics Module
The extraordinary build quality
would be just more mumbo-jumbo
if it didn’t mean that each note from
the BUDA is precisely held in space,
and perfectly black between it and
the next. The BUDAs innards fairly
bristle with high-quality capacitors
of various types hand soldered to a
superbly laid-out main circuit board
providing supply decoupling and low crosstalk among the various audio
sections. From the silky-smooth Alps RK27 and Neutrik Combo jacks on the
front panel, to the Cardas RCA connectors on the rear, to the satin black
aluminum and urethane bezels of the enclosure, this amp is built to please
now well, and well into the future.
BUDA Amp Circuit Boards
At the very core of your Balanced Ultra Desktop Amp are our Max electron-
ics modules. The two critically matched pairs of circuit boards provide the
left and right, and normal and inverted channels of this differential-drive bal-
anced headphone amp. Populating each ultra high quality 4-layer board are
some of the best metal film resistors and polyphenylene-sulfide caps that
money can buy. All active stages are biased into class-A operation; buffer/
crossfeed stages are all implemented with the legendary OPA627 op-amp;
and the output amplifier is our version of the highly regarded discrete compo-
nent Diamond Buffer design by Walt Jung.
Four of the Max Modules are used
in every Balanced Ultra Desktop
Amp.
BUDA Amps feature a
power supply filter board.
