OVERVIEW:

This is the 10th year anniversary edition of our original Zen Triode amplifier.  It is 2 watts x 2 or 6 watts x 1 single-ended triode design capable of driving loads down to an almost ridiculous one ohm.  

A completely purist design, hand crafted amplifier with only 1 capacitor and 2 resistors in the signal path.  Even hook-up wire is eliminated with everything connected parts lead to parts lead.  Of course there is no circuit boards and no Chinese parts.  Our amplifiers have proprietary US made power and output transformers of outrageous quality.  It is an amplifier that will get the undivided attention of even the sickest audiophiles!

The only problem with this amp is the price.  Audiophiles who are always looking for a better sounding amplifier have owned  and presently have amplifiers costing many times this amount...  so it becomes almost impossible to wrap their brain around the simple fact that this amplifier could sound better than theirs.  If you're a serious audiophile, try it on our 30 day money back trial and see for yourself.

STYLES:

This amplifier comes in two basic styles made possible by interchangeable hardwood bases. The amp shown above is in the black base.  The amp shown here is in a contemporary solid walnut base.  You may choose between the two bases when you order your amp.  We can also custom manufacture the base below in any hardwood, including exotics for an extra cost.

FEATURES:

The SE84ZS amplifier has both direct and variable inputs so that you can use it with or without a preamp.  We recommend if you own a preamp to try both using and not using it to see which is actually better.
 

IDEAL SPEAKERS:

We have 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.  If you 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.

SPECIFICATIONS:

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 tubes wired in triode were chosen over 300B, 2A3, 45, and other triodes for having the best sound and imaging.

VOLTAGES

This amplifier comes standard with our World Voltage Compatible Transformer. Your amp will be automatically wired for the correct voltage for your country and be supplied with the correct removable power cord.  

2ND GENERATION:

The original version of this amplifier was called the SE84CS, the S stood for "Select".  It was a select version of our original amplifier, the SE84C, that we still make today.

DESIGN NOTES:

The original SE84CS Design notes still apply.

OWNERS MANUAL:

TUBES:

This amp is shipped with graded premium quality 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 unparallel 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 tubes.

The input tube is a single 6N1P, 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 particular tastes.

The rectifier is a 5U4G and can be substituted with a 5AR4 or compatible rectifier.  Many owners of this amp like using the 274B.  Each rectifier change will also make audible differences in the sound and performance of the amplifier.

CABLES:

This amplifier is so transparent that differences between cables will now become big differences.  If you don't have good interconnects or speaker cables or just not sure how good yours are we offer affordable reference quality cables that will let you hear how good this amplifier and your gear really is.
