FEATURES

The Zen TABOO MK III has several features that combine to make it one of the very 
best quality headphone amplifiers in the world.

 SINGLE ENDED DESIGN - One output tube per channel running in class A. The benefit of 

this is in the detail. 

 

Multiple tube designs are never quite as transparent as a single tube.

 NO CIRCUIT BOARDS - Wired point-to-point with parts leads and no hookup wire. The 

benefit of this is better sound combined with reliability that is so great we offer a lifetime 
warranty.

 SMALL OUTPUT TUBES - Uses your choice of EL84/6BQ5 or SV83/6P15P output tubes. The 

benefit is these tubes have better speed and neutrality than the pricey alternatives.

 VOLUME/GAIN CONTROL - Front mounted gain control makes it possible to use this amp 

without a preamp OR allows the input sensitivity to be adjusted to achieve optimal matching 
with

 

any preamp.

 

 Comes with a Gold Contact Precision 20 pos Stepped Attenuator.

 GOLD/TEFLON INPUT JACKS - Rear mounted, high quality RCA jacks are wired with Silver/

Teflon wire to support even the most expensive interconnect cables.

 DUAL INPUTS - Run two different sources switchable through a silver selector switch.

 ADJUSTABLE INPUT LEVELS - independent input level adjustment for all 4 channels.

 DUAL 1/4 HEADPHONE JACKS - located on each side and can be used at the same time 

making it possible for two people to listen.

 XLR BALANCED OUTPUTS - available in either 3 or 4 pin XLR to accommodate different 

types of balanced headphone cables.

 FLIPPED OUTPUT JACKS - The top mounted speaker binding posts are flipped so high 

dollar speaker cables lay out correctly without one being twisted. 

 

These accept banana jacks, 

spades, or bare wire up to 8 gauge.

 BIAS METERS - Supplied for each output tube, the meters show how many milliamps each 

output tube draws.

 

 A great indicator of the condition of the tubes and how well they match.

 USA MADE CUSTOM OUTPUT TRANSFORMERS - Our output transformers are designed 

from the ground up with premium cores and non-symmetrical windings especially for these 
amps. 

 

There are no off-the-shelf high-dollar

 

output transformers made that sound better. 

 

These transformers are a large part of the reason Decware amps have gained the reputation 
they have.
