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
is the highly tweaked version of our original Zen Triode amplifier, originally released in
1998. Since that time it has developed an almost cult following
among serious audiophiles.
If you've done your homework, you already know the Zen Triode IS the
best value in 2 watt amplifiers anywhere. It is preferred over directly
heated triodes for having more speed, better micro detail, better bass,
and most of all better neutrality. It's sound stage and 3D imaging
are as good as either one can get. It sets a benchmark that's
immune to price points and gold plating.
Now for the first time ever it has the two things
asked for most: Meters and optional balanced XLR inputs!
SE84CKCS Select Zen Triode Amplifier shown in black figured base
100% Tube Amp with no solid state parts or circuit boards. Single
ended triode design. 2 watt x 2 Stereo amplifier bridgeable into
mono, 6 watt x 1. Can handle speakers with dips as low as 1 ohm
with no loss of bass control. Features a signal path with only 1
capacitor and 2 resistors. Uses 6P15P-EB or EL84 output tubes
driven by a single 6N1P-EB or 6922 input stage. Tube rectified
using 5U4G or equivalents. Hand Built in the USA by skilled and
well paid artisans, 30 day in home trial, lifetime warranty.
Preamps are optional. Amp comes standard with two pair of RCA
inputs so you can switch between two different sources. (XLR
inputs are limited to one source only)
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

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 this good -
but the Zen amp does.

Optional Transformer Balanced XLR Inputs are available as an option on this amplifier
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.
output channels are self biasing so meters have been provided to show
you if you tubes match. They also show you how strong your tubes
are, as well as when or if the amp is clipping.
Worried about 2 watts being
enough power? Bridge the amps into mono and quadruple your power!
SE84CKCS amplifiers 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 SE84CKCS 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 with gold grids 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
You'll find the 6N1P-EB 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

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.

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.
