Theta Citadel 1.5
Monoblock Amplifier pair

MSRP $25,000.00 Basically brand new but priced for rapid sale to cover a mega purchase. Preference given for local pickup.

This ad is for a black pair of the
powerhouse+finesse performer Theta Citadel 1.5 mono amps. These mega-amps have
incredible attention to detail and look and sound great. They are
conservatively rated at 400 WPC into 8 ohm (see specs below) and are extremely
musical despite the power. 

 

I purchased these new for a system
that I never got to put together. I never used them and only unboxed them now
for the first time to take pics, plug them in and make sure there were no
issues before selling them. They are in out-of-the-box condition literally. These retail
for $25,000.00 and sell used for a bluebook of $15,696.25 (and a pair is for
sale in 6/10 condition on a dealer website right now for $17,995.00)! At this
price, these should go fast and I congratulate the winner. They are worth every
penny even at MSRP.

 

If you haven't heard them, you
should check out the many rave reviews of even the prior less refined versions.
They are effortless, incredibly fast, and seem to have infinite reserves. They
are Theta's best powerhouse monos. At this price they are an absolute steal so
you cannot go wrong. 

 

Stereophile reviewed
the prior version (and this one beats the golden-ear prior dreadnaught too!): Jonathan Scull, under the heading
'Sound', proclaims "... a woman's voice floats way back in the soundstage.
The first time I heard it, I wanted to dive into that soundstage to inform this
woman that I was the guy she was singing about, grab her, and...er, give her a
big hug."

"... I
noted that affinity for beautiful, grainless female vocals and a full and
lovely midrange... I turned the volume up. Then the Citadels hauled off and
gave it to me, top to bottom, in a manner most remarkable-the bass... took on a
dynamic, articulate, detailed, and powerful sound at higher volumes that was
just splendid."

"J.S.
Bach's Adagio... made the hairs on my neck stand straight up. The air, the
emotion, the microchanges in volume and the sounds of bow on string-it all made
my heart race with pleasure."

"... a
certain litheness, delicacy, and transparency in the Citadel's
reproduction."

"...
the Citadel was superb, just superb."

"Heaven."

From Theta:

The Citadel
1.5 is a monoblock power amplifier offering all the advantages of the
knowledge, research and dedication that Theta Digital has brought to its other
amplifiers, and then some.

 

The heart of
the Citadel 1.5 contains fully-balanced differential, zero-feedback circuitry,
and zealously selected solid-state devices throughout. We scrutinize the
selection to optimize component parts in each and every stage, and for the
performance of the amplifier as a whole. Custom-made capacitors, Vishay
precision resistors, copper buss bars, Litz / Teflon wires and a custom-made
output connector are just some of the components that combine to make the
Citadel 1.5 an unprecedented technical statement.

 

Sonically,
this quality is expressed as a new level of veracity and intimacy in the
experience of music, and in the prospect of movie soundtrack performance that
no commercial theater can hope to rival.

 

The Citadel
1.5's power supply design is an exercise in delivering massive brute power with
absolute integrity. We give its output stage a high-current Kilowatt power
transformer itself, which feeds a unique dual-choke and capacitive filtering
system. This technique is rarely applied because of the huge choke size
necessary to avoid impeding high current demands. Its filtering system employs
two massive chokes almost as large as the power transformer. These are fed from
an ultra-fast / soft-recovery 35 Amp full bridge rectifier, which are then
filtered by two capacitive banks totaling 80,000uF. The synergistic effect of
this filtering system results in high-current power supply lines that are more
than 8,000% cleaner than conventional supplies.

 

The sonic
result of these super-clean supply lines to the output transistors has not
previously been achieved at such a high power levels.

 

The
mechanical housing for the Citadel 1.5 is no less specialized than its internal
components. More than an aesthetic statement, its seamless housing, devoid of
traditional fasteners on top, front, and sides, provides a strong, stable
environment for the operation of the amplifier. The power supply resides in its
base, isolated from the amplifier module above.

 

The Citadel
1.5 has been created to power the most demanding two channel and home theater
systems, effortlessly recreating the vast spectrum of music and soundtracks
with both silky finesse and authoritative control.
