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.
