Coincident Amplifiers

Turbo 845SE

In response to the demand for a state of the art stereo integrated single ended triode amplifier, we are pleased to introduce the Turbo 845 SE. This amplifier is built and designed to be an all out assault on integrated stereo amplifiers. It is constructed as true dual mono in every way. The only shared component between the two channels is the chassis. The Turbo is built on the same chassis as our current Dragon MK II amplifier( slightly larger and heavier). The Turbo was created for those who do not want to compromise quality or performance but are limited to space which preclude mono amps and a separate preamp. The Turbo has the convenience of remote control and having the line stage and stereo amplifier all in one chassis. A further benefit is that no extra cables are required for hook up. The Turbo also serves as a state of the art headphone amp. A convenient front panel headphone jack is included. Output impedance is a standard 300 ohms (can be changed to any value).

The Turbo has an enormous power supply and generates 28 watts per channel which means it can power optimally most sensibly designed speakers. Ultimate transparency, purity and flat frequency response are the sonic result.

Dynamo 34SE

For those on a budget but who still demand top flight sonics and build quality, the Dynamo will prove to be a revelation. Single ended triode tube sound that belies its 8 watt power rating. Any 90 db sensitivity speaker can be powered with startling clarity and dynamics. Build quality not seen at twice the price. Perfect for those who want a simple compact set up or as a second system where true musicality is insisted upon. Hard to believe that this much performance and quality can be had for under $1300.Volume control obviates the need for a line stage since it permits direct connection to a CD player or DAC.

211PP Dragon MK. II Mono Amplifiers

“This is the finest high power amplifier I’ve ever heard. In short, my associates and I hear a combination of sonic strengths we’ve never heard before.” – Arthur Salvatore- High End Audio

We are now excited to introduce the MK. II version of the highly acclaimed Dragon amplifiers. The improvements include:

1. Dual power transformers in place of the previously used single unit. The new transformers individually possess the capability of powering the amplifier. In tandem, they are coasting only using less than 25 % of their rated capabilities. The result is a far cooler operating amplifier, thereby improving reliability and long term
stability. Additionally, the Dragon is now virtually noiseless. It is incredibly quiet which is a remarkable feat for an amplifier this powerful operating at such high voltages. Sonically there is an improvement from top to bottom. The bass is tighter, deeper and punchier. The mids and highs are more transparent and the soundstage more expansive. Due to the reduction in noise, overall revelation of low level detail is enhanced.

2. Chassis Rigidity – To accommodate the dual transformers of the MK. II Dragons, the chassis has been enlarged by 20%. The amplifiers are now 2″ wider and 2″ deeper and 1″ higher. They now weigh 85 lbs, which is 20 lbs heavier than the previous model. The chassis is now more rigid which results in the virtual elimination of chassis induced resonances. The MK. II now utilizes 6 ceramic isolating feet to stabilize the unit.

3. The standard supplied 211 tubes will now be the exceptional Shuguang Pevane.They represent a marked sonic improvement over the previously supplied standard Shuguang. The Pevane is also more durable and reliable and runs 15% cooler.

4. AC ground lift is now included. This switch conveniently eliminates hum created by AC ground loops.

The MK. II Dragon is now the finest sounding, high power amplifier in existence. Its purity is within a hair’s breath of the finest SET 300B amplifiers (the Frankensteins) yet its power delivery is awe inspiring. It also runs cooler and is exceptionally quiet.

Features include:The purity, transparency and continuousness of a DHT SET but with the power, explosive dynamics, weight and impact of a huge push pull pentode amplifier – sounds mutually exclusive, not any longer. The 211PP Dragon mono amplifiers are such a creation. These amplifiers are absolute state of the art in terms of components selected, circuit design and execution and construction quality. This is unique among high power, push pull DHT triode amplifiers. There has never been a high power, DHT amplifier built to this standard with sonic performance at this level. The Dragons are capable of driving even the most difficult speaker loads.

  • The finest 6N copper interstage, output and dual power transformers
  • Tube compliment- 6EM7 super tube for input- So much current capability it has its own power supply
  • 300B Driver Tube for utmost purity ( no pentode tubes used in this DHT design)
  • Dual 211 Shuguang Pevane output tubes in a push pull configuration which dramatically lowers distortion and provides huge power reserves. (over 120 watts of peak power- 80 watts continuous- sounds more like 150 watts)
  • Teflon caps use in cathode bias circuit
  • Power supply caps are all 1500V polypropylenes
  • Highest quality discrete resistor potentiometer permit the direct connection of a CD player thereby obviating the need for an expensive line stage
  • Binding posts are Coincident 6N copper, .25″ solid post
  • Auto bias
  • All resisters, red metal film, 1% and none less than 2 watts
  • All meticulously hard wired
