at least 5 hours.  
 
Once you have repeated this process 5 times your soundstage will bloom and the focus will lock 
into a crystal clear image. 

 

If you listen to your amp during the burn-in process this is what you will experience:  First the 
amp will sound good followed by almost an immediate increase in harshness which after 30 
minutes will change to dullness and continue to go back and forth.  During this mind bending 
experience, the imaging and soundstage will be unstable and somewhat restricted. 
 
There will be moments of incredible sound during this process and equally ugly sound.  You will 
know when the amp is burned-in because out of nowhere some night when your listening the 
amp will bloom with a soundstage almost double in size and forever stay that way in all 
successive listening sessions.  As you amplifier ages, it will season like fine wine and continue 
to do so for many years. 
 
 

DESIGN GOAL 
 

The design goal behind this amplifier was simply to take our stock Zen Triode amp and push the 
envelope of its design to the limit.  It uses all the same parts as found in our Signature Mono 
Blocks (model SV83S) and is every bit the equal in fidelity when power is not an issue.  Perhaps 
the purist amp in the world you will likely never find it to be the weak link in your audio system.  
Since you only hear the weakest link in a high end audio system, you will find the quality of your 
source and cables as well as your speakers to effect profound changes in the overall fidelity of 
your system. 
 
Like the stock Zen amp, this is intended for those who like to get lost in a huge  3-D image and 
experience the emotional side of music that only this type of resolution can accurately convey 
without grain or ear fatigue.  It is not intended for loud playback levels, or parties.  Unless of 
course you have full range horn speakers around 100dB  
efficiency in which case you can have both.  We recommend 4 ohm speakers with simple 
crossovers that are in excess of 90dB for most listening.  This amplifier will run speakers down 
to less than 1 ohm, and put out more power as it does so.  Therefor you need not be concerned 
about dips in your impedance curve when choosing a speaker.
