Transformer Coupled hybrid mono block "as new" pair cost no object in handsome Black a true Reference tube pair of amplifier's ready to be enjoyed by you❓
HIGHLY RECOMMENDED ‼️
Price lowered for fast sale at this price as new it will not last 🎶 👍👍...
Less than 200 hours barely broken in with factory boxes.
A truly great opportunity & the matching Phono section the Thrax Orpeus Phono reg $19,500 for $10,500 both also as new and one
owner and as new factory boxed both listed on Audiogon separately.
Teres is based on classic tube amplifier topology. Tube clarity and tone with might and power.
Audiophile long life input tube
Silicon carbide rectifiers
Shunt regulated power supply
Solar cell bias of output stage
Special grade screened power transformer
JFET/MOSFET cascode output
Available in stereo and mono version's =============================
Single-ended tube input stage loaded with a phase splitting
transformer controlling 2 separate out of phase single-ended amplifiers
The tube handles all the voltage gain needed. It uses a new
generation or our choke rectified shunt regulated power supply providing
a noise-free operating point.
The output stages power JFET cascodes form a bridge that when
unbalanced by the input signal via the 2 transformer windings restores
balance by adjusting their current conduction through the load. The 2
output stages actually enclose the load in their control loops and try
to correct each-others errors reducing the distortion to insignificant
amounts, leaving the "character" of the input stage untouched.
reduce the amount of heat generated the amplifier is biased so only the
first few watts are in true class A. Music has a crest factor of 10 on
average. This means that most of the time we listen with 1/10th of the
peak levels. For most users this translates to under 5W. Peaks can reach
over 100watts during playback, but only for few milliseconds. For those
peaks the amplifier switches to class B using only one leg of the
output stage capable to deliver up to 250W/8ohm and 350w/4ohm (120W/8Ohm
and 170W/4Ohm Stereo).
Not sharing a common reference point apart from the load itself
makes the second leg correct for any error produced by the first one.
The result is an amplifier capable of extreme power while delivering
exquisite smoothness and low-level resolution.
The driver stage is isolated by the interstage transformer and is not
influenced in any way by the output stage maintaining tone colour and
resolution at all power levels and loads.
Having the output stages floating around the load prompted for the
use of a unique biasing technique powered by solar cells. This was the
quietest galvanic isolated power we could come up with. Using
opto-electrical conversion we control the bias by adjusting light
intensity in the control circuit.
Teres is an example of modern technology solving age-old problems allowing us to go a step beyond.
The physical appearance of Teres has the kind of understated
elegance typical for Thrax. The exquisite aluminum finish adds to the
presentation of a solid block of metal like a bigger brother of Heros.

Artaski was right, the Thrax Audio is addictive and I need HELP because
I am hooked. Yep, I pulled the trigger and purchased this review
sample. Ladies and gentlemen, it’s that good a product. At $30k, It’s
not inexpensive but the Teres hybrid mono amplifier brings so much to
the table that, relative to other reference amplifiers in today’s
market, it’s a bargain. They produced magic with every listen including a
new reference of quiet, speed, and transparency. Timbre rightness
coupled with color density and warmth is what ultimately won me over.
Hats off to Rumen Artaski for creating a new benchmark so close to his
superb sounding Spartacus, with lower voltage and no exposed tubes and
can be used with mainstream loudspeakers. The Teres has earned my
Stereotimes 2015 “Most Wanted Components’ award. Highly recommended!
