you haven't heard a Zen Triode Amplifier... you're in for a really
pleasant experience! It floats music in 3D space like very few amplifiers
can. Designed and built in the USA it comes with no
The Zen Triode is a single-ended
amplifier that out performs most popular amplifiers with a simple
less-is-more approach. Less internal parts, More realistic
sounding music. Of course there's a fair amount of good Karma that
comes with hand building each one without circuit boards!
is the highly polished version of our original Zen Triode amplifier, originally released in
1998. Since that time it has developed an almost cult following
among serious audiophiles.
adhere to the 'first-watt' theory of HiFi, here’s a bonus:
the Decware Zen amplifier gives you two. Yep, two watts per channel
single-ended triode. i must admit they are pretty big watts, as i had
no problem driving my reference GamuT s-7’s to a more than reasonable
level. (The s-7’s have a rated
sensitivity of 89db at 1 watt and a retail price of $42k per pair.)"
"What really sets the Zen apart from all the moderately priced tube
amplification i’ve heard is its incredibly lifelike tonality
-Jeff Dorgay, Tone Audio Magazine
Single Ended Triode
amplifier is capable of driving almost a dead short - rare in the world
SET amplifiers! It can be driven directly from any source (such
as your CD player or DAC) without a preamp. It will drive typical hi-fi
speakers to conversation listening levels and hi-efficiency speakers
(94dB 1w1/m) to a satisfyingly loud level. The amplifier operates in
pure class A and has zero negative feedback.
The bass surprises
everyone, and the amp features two inputs and a selector switch so you

Tubes for it are more than affordable, the amp is self biasing
making it a completely hassle free experience to own and enjoy one.

WHY DOES THIS AMP
SOUND SO MUCH BETTER?
produced. It's hand-built, point-to-point wired using only part leads
limit the solder nodes. Only 2 resistors and 1 capacitor are in the
path and there is a Silver ground buss. It uses US Made proprietary
output and power
transformers in a high mass steel chassis of the highest quality -
all built by skilled (and well paid) artists here at Decware.
The SV83 output tubes are among the most linear in the world when
triode wired.* We think
that this tube is the most neutral sounding. And then there is
owner of Decware, Steve Deckert's flawless Zen design that
separates this amp from other high quality boutique competitors.
There's been so many 300B and 2A3 amplifier owners that have switched
to the Zen Triode that we've lost count. We bring that up because most
people who haven't heard one can't wrap their head around the concept
that an amplifier costing less than a grand could sound better than a high dollar amplifier -
but the Zen amp does. The more you read about it and learn about Decware the easier this statement is to believe.
* SV83/6P15P-EB Data Sheet.
The SE84CKC amplifier has an exquisite black powder coat finish reminiscent of the old typewriters from the 1930's.
It has 2 pair of inputs so that you can use it with
2 sources, a front mounted volume control, a silver toggle switch for
source selection and a silver toggle for the different bias settings of
the input tube, just like always.
It uses EL84, or SV83 output tubes and
your choice of 6N1P, 6DJ8 or 6922 input tubes.Compatible rectifiers are 5U4, 5AR4, 5Y3GT and some 274B's.
Top Quality Gold / Teflon input jacks and fused IEC connectors are provided for use with hi-end cables. The amp
is self biasing so you never need to adjust the bias and the bias will
never drift out of adjustment. While we ship it with a military grade version of the SV83 called a 6P15P-EB featuring Gold plated Grids from Russia.
The output channels are self balancing meaning it is also possible
to use non-matched output tubes without channel imbalance.
Worried about 2 watts being
enough power? Bridge the amps into mono and quadruple your power!
SE84CKC employ a unique floating
output transformer scheme where the negative speaker wire is not tied
to chassis ground. That means when the amp is bridged, both channels
may either be series or parallel wired. In series, both channels work
as one and transparency is preserved.
no sonic drawbacks to running the amps
in mono, you can expect 6 dB of additional power rather then the
expected 3dB. This is thanks to the power increase the amp has when it
sees half the speaker load from being series bridged.
successfully driven hundreds of different
loudspeakers ranging in efficiency from 90 to 100dB 1w/1m. On 90dB
speakers it works nicely in smaller rooms or for late night out of body
experiences. 94 to 96 dB speakers are almost ideal in that they let you
play beyond a normal listening level and preserving the dynamic
headroom. When these amplifiers were first released in 1997 there were
a minimal number of "high efficiency" speakers to choose from. Today
that is no longer the case - they are everywhere. We also offer several
different types of loudspeakers that will work with this amp.
own speakers that
you love and are afraid this may not drive them understand two things:
A) It will drive them louder then you're expecting and B) you can
bridge these amps into mono blocks. Because of the power increase
into lower ohms, you will net 6dB of additional power. Same thing as
doubling your power... twice.
The SuperZen can be configured for speakers between 2 and 6 ohms OR for speakers between 6 and 16 ohms from within the Shopping Cart.
N.O.S. 6P15P-EV output tubes rated at 5000 hours. These Russian
military spec tubes are the top grade of what we came to know in this
country as the SV83. You can also use EL84's without adjustments of any
kind. You'll find the SV83's to be unparalleled in speed and
detail - in part because it is a video tube with much wider bandwidth
then a normal audio tube. We think these are the best sounding
most transparent tubes available today. The EL84 (6BQ5) is a bit warmer
sounding giving the amp a different signature by just switching output
6922 or 6DJ8
- your choice. 6N1P's have the warmest tone, 6922's have the best
dynamics, 6DJ8's have the most air and micro-detail with a touch less
bass. Again, a powerful tool for voicing your amplifier to your
rectifier location is compatible with 5U4G, 5AR4, 5Y3GT, and some 274B. Many owners of this amp like using
the 274B however not all 274B tubes are completely compatible, so we
ship the amp with one that we know IS. Each rectifier change will also
make audible differences in
the sound and performance of the amplifier.
cables will now become big differences. This is true
for both interconnects and speaker cables. Be sure to try a
couple different cables along the way as your amp can only sound as
good as the cables connected to it.

amp going back 15 years.
Manufactured from 1998 to 2008 and was retired at serial number 1000.
This unassuming little gray box (about the size of a toaster)
set the benchmark for all Decware amplifiers that followed.
SE84C+ / Manufactured from
2008 to 2009. The chassis was stretched an inch, the larger world
voltage power transformer became standard. The thickness of the steel
chassis is doubled and the paint is changed to high gloss black powder
The volume control was moved from the rear to the front. A second set
of input jacks was added with a silver switch so you can run 2 sources.
SE84C+ / Manufactured from 2009 to 2012. The
front mounted switches were moved slightly to make room for an upgraded volume
pot. Binding posts were upgraded. Finish was changed to a
high gloss piano finish in white. Internally this amplifier now uses the CCE mod which stands for "Christmas Comes Early" and deals with
improving the operation of the output tube suppressor grids.
SE84CKC / New for 2013. Known as the
"SuperZen" the chassis has been improved again with a 1930's typewriter
finish. By far the best sounding version to date due to a
re-voiced front end. It's now using large 2 watt carbon
composition plate resistors and silver-leaded waxed foil caps by Jupiter
that were found to sound better in this amplifier than VCAPS.
Vcaps were a $200.00 option in the prior model. We named this
update the CKC mod which stands for "Christmas Keeps Coming" which can
be seen in the model number.

"Just for the Holiday I went back to my white #018 Select for the week of Christmas into new years , Happy New Year. Last
night I switched back to the Superzen And again in my 9x13 room with the
ZCD200i and common sense audio 2.8's with 10"cast frame audio
nirvana's. The dynamic was such that I thought I switched over to a much
more powerful amp. Just amazing with both amps volume at around 9
O'clock. normal listening level here . The only thing I did do was run a
dedicated circuit to my breaker box . Highly recommended.........So The
Superzen has come to be truly super compared to past zens, which I have
4 of in various vintages."

This amplifier requires no adjustments
or maintenance other than changing tubes every couple years. It is a
self biasing design and self balancing meaning even unmatched tubes
become matched when installed. The SV83 (6P15P-EV) or EL84 output
wired in triode were chosen over 300B, 2A3, 45, and other triodes for
having the best sound and imaging.
