tained "energized".

form of pre-assembled and tested 
modules.

minimum of 5 complete sets – of all 
mechanical and CNC machined com-
ponents. 
-  A total number of transistors equal-
ing 120% of the number of complete 
machines sold, ensuring another en-
tire electronic life to each darTZeel 
NHB-108 model one sold. 
-  A number of electrolytic filtering 
capacitors equal to the number of 
darTZeel NHB-108 model one units sold 
and reaching their 25th working year. 
-  All diagrams, electronic and mechani-
cal drawings, in paper and computer-
ized versions.

ously updated, of components suppli-
ers, CNC makers, and all other com-
ponents involv ed in the darTZeel NHB-
108 model one construction. 
-  A complete computer system, con-
tinuously updated, allowing retrieval 
of the above-mentioned data at any 
time. 
-  A fully detailed manual explaining 
how to use and to work with all the 
above. 
All these items have been put in a nitro-
gen-filled con tainer, in a safe area. 
In the improbable case of darTZeel's dis-
appearance, or if we ourselves can no 
longer intervene, you will be given a 
copy of these documents. 
In such a sad case, our notary office will 
directly contact every owner with appro-
priate instructions. 
Life is such a wonderful thing that we 
strongly hope that we will be able to 
serve you for many decades to come. 
10. The next darTZeel 
Now that we are almost at the end of 
this manual, we do think that you have a 
better idea about our philosophy. 
We just hope that we have not fright-
ened you by our unusual way of 
thinking. After all, if you proudly own 
one of our machines, it is because you 
have trusted us. We just say: "You were 
right!" 
Nevertheless, do not believe that we set 
such a high level for the darTZeel NHB-
108 model one that no one could ever im-
prove it. 
Obviously we do not want nor even need 
to change our product line every year, or 
even every 5 years, but this does not 
mean that we will rest on our laurels. 
The design of the darTZeel NHB-108 model 
one incorporates the best that this be-
ginning of the 21
st
 century has to offer. 
We sincerely think that at the time of 
going to press it is not possible to go 
much closer to the sonic truth than that 
which the darTZeel NHB-108 model one is 
already capable of providing. 
As the years go by, technology will re-
lentlessly improve. We will endeavor to 
determine to what extent we can go 
even further. 
Each time we can make a leap forward, 
we will do so. 
Every darTZeel NHB-108 model one can be 
easily upgraded at any time. So when-
ever an improvement becomes available, 
every customer can enjoy it at an attrac-
tive, real world price. 
At the time of writing, we think that a 
significant update could take place every 
3 years, on average. These updates will 
be of two different kinds: 
Music Lover updates, where sonic as-
pects only will be improved. 
Audiophile updates, where sonic and/or 
technical improvemen ts will be offered. 
Of course every sing le owner will b e kept 
informed about any significant new de-
velopment concerning the darTZeel line.
