Sima 2002

SPECIFICATIONS:

 

"In the early 80's an amplifier was considered good only if it had very low Total Harmonic Distortion (THD) figures. In order to obtain low THD, designers used massive overall negative feedback techniques. During this era, Victor Sima was the head of Sima Electronics Company where he developed a different approach to amplifier design; Amplifiers designed with low negative feedback.

The approach was to look at each stage of the amplifier as an individual amplifier, then reduce local feedback and extend the frequency response as much as possible. Listening test were used to optimise the local feedback current and voltage of each stage. After optimisation, the individual stages were connected together to form the whole amplifier. The amplifier then passed a series of bench tests with resistive and complex loads to ensure stability. This design approach didn't have the impressive distortion figures of amplifiers using overall feedback, but had more impressive sound quality, and for most audiophiles that is what matters most. Still today, this is a widespread design approach amongst many well-known amplifier manufacturers."

OTL design, Twelve  of the fabulous Russian 6C33 dual triode tubes per monoblock.  Output power is 220W into a 8 ohm load which only drops to 160W into a 5 ohm load. Unlike previous Joule-Electra OTLs, these guys have the power supply for the amps fully inboard. Each monoblock amp requires two power cords (detachable 15A IEC types), one is used for the filament power supply and the other powers the rest of the amp. A feedback control allows continuous adjustment of feedback on each amp. Bias adjustment for each tube is easily adjustable from the top of each amplifier.

 

Very rare power amplifiers.

 

Summary:

 

The Rite of Passage Monoblock amplifiers are indeed passage into a higher realm of audio performance. Harmonic thunder in a bottle, these amps deliver the musical goods unlike any other large amplifier. Unconstrained dynamically the Rites allow music to emerge with uncommon grace, speed, control and finesse. The Rites are designed to function in large scale systems and couple with even the most demanding loudspeaker to yield truly "great" realization of any musical program. If your system and room are capable of this level of performance, these amplifiers are the stuff of legends. Arguably, the most capable amplifier on the planet. Beginning with a Golden Ear award from the Absolute Sound in Dec. 2001-Jan. 2002, and still being discussed, the Rites are to receive a full review in an upcoming issue of The Absolute Sound.

 

Joule Electra, based in North Augusta, South Carolina, specializes in high-performance vacuum tube electronics for audio reproduction. Marianne Barber is the Vice-President of Joule Electra and Jud Barber is the President and also the designer of all Joule Electra products. Joule Electra is praised the world over for their high quality products, exemplary craftsmanship, and commitment to bringing musical realism closer to the home.

Defines the absolute state of the art in harmonic structure and tonal purity.

Both items for sale together only.  For information on the Jadis JA80 power amplifier, see below.

 

"The JP30 channel-separate buffer capacities for each individual amplifier stage, in order to exclude interactions between the stages. They stand for left and right channel separately on the left and on the right. In order to obtain absolute channel equality, each of the tubes works as double triode for both channels."

Stereophile Recommended Class A rating, under tubes.  This is the Silver version, not the normal version

 

Audio Note Kassai silver

Magazine: Stereophile
Reviewed: Apr 1996, vol 19, iss 4
Reviewer: Jonathan Scull
 

"This stereo power amplifier uses Asian 300B tubes in pure Class-A mode without feedback in a single-ended parallel circuit.  The output transformers are made of 10 to 12 year old copper, the secondary winding is made of 99,99% AUDIO NOTE silver.  A pure copper chassis, free silver wiring, paper in oil capacitors and double-mono power supplies with tube rectifiers meet the uncompromising quality demands of AUDIO NOTE.

Jeff Rowland 8Ti power amplifier   (SOLD - Singapore)

In excellent condition, near-mint, all packing boxes intact, manual.  Another beautiful piece of hifi.

 

"The title of world's finest stereo amplifier is highly coveted in the audio industry. With the newly redesigned Model 8Ti from Jeff Rowland Design Group, a new contender has just entered the ring.

The Model 8Ti combines the same chassis rigidity, differential balanced circuitry, dual-mono power supplies and isolated transimpedance amplification of its predecessor with two important differences:  Jeff Rowland Design Group's visionary application of input transformer technology (the "T" in Ti) and utilization of "intelligent" bipolar output power transistors originally developed and used in the Concentra integrated amplifier (the "i" in Ti)."

The legendary first product produced by Pass Laboratories. 

 

"Over the years I have remained fascinated by the characteristic sound of the single ended topology, but until now I did not have the opportunity to bring such a product to market.  A very few people are involved in the production of this product. I supervise all phases of the construction, and I test and listen to each amplifier myself." - Nelson Pass

ONE OF THE BEST 300B AMPS KNOWN TO MANKIND

Zanden's model 7000-300B amplifiers are single-ended stereo triode designs.

They have been engineered with a single purpose: the realistic reproduction of live music. To this end no detail has been overlooked and Zanden has truly created one of the world's finest SET amplifiers.

Like all 7000 line amplifiers the model 7000-300B benefits from a unique patented 3rd stage NO-NFB (no negative feedback) direct coupled vacuum tube circuit. The power supply is constructed entirely from tube rectifiers to exclude the switching noise of diodes. A PC board is utilized to achieve the shortest possible signal path, and the highest quality parts are used throughout, including polypropylene film caps. The base, front and rear panels are constructed of 16 mm thick aluminum to keep vibrations to a minimum.

The unit is then covered with beautiful stainless steel polished to a mirror finish. An excellent passive volume attenuator made by DACT is also included, so the model 7000 can be used directly with a CD player or similar source.

The 7000-300B uses possibly the world's most beloved triode, the 300B. The 300B delivers unrivalled midrange beauty, detail and realism. It truly is the music lover's tube.

Selling Price:

SGD 1500

"Despite the name, the B-300XS is not an upgraded B-300, but rather a version of Densen•s forthcoming top of the line B-320 monoblock power amplifier. Compared to the normal B-300, the B-300XS is still 100W per channel, but in all other aspects significant superior. The XS therefore indicates excess•. The new B-300XS contains a completely new output stage, build using Densen•s unique: "DMCD" technology (patent pending). This makes the B-300XS extremely fast and precise, while retaining unlimited control with the speakers. Also the bandwidth has been improved, and the B-300XS goes straight to 400.000Hz, resulting in improved slew-rate, which makes movement and stop/start transients perfect."
