RESTEK & TRIGON Amps.

RESTEK: UNCONDITIONAL QUALITY SINCE 1975

Auth. Dealer – Repair – Exchange Very experienced service workshop – Service is performed, please inquire. At VintageAudio there is always a fair and reasonable price level, also on repairs of the eminent German High End amplifiers. Restek service and repairs are extremely demanding and make very high demands on the repairman. We cooperate with highly specialized and very experienced service workshop, we are happy to provide assistance. Restek Update Service in Fuldabrück accordingly.

Price: € 5400,- The EPAL integrated amplifier also serves demanding and power-hungry loudspeakers: it delivers 2 x 680 watts at 2 ohms, 2 x 360 watts
4 ohms and 2 x 180 watts at 8 ohms. However, two devices in bridge can also be connected as mono devices. Then a stereo system even delivers 2 x 900 watts. Damping Factor > 1000 and Distortion Factor less than 0.005%.

Price: € 5600,- Internally, the DC-coupled EDITOR consists of two separate, fully symmetrical, identical mono preamplifiers, each with two volume controls. So there are a total of eight potentiometers. The inputs are switched via high-quality signal relays. the earth connections of the non-switched input sockets are separated from the device to avoid ground loops. The input sensitivity of the selected input can be adjusted within a range of ± 6 dB to compensate for volume differences when switching between the individual inputs. Using the volume control, the signal can be attenuated down to -95 dB or amplified up to +10 dB. The two separately controllable outputs can be leveled against each other in a range of ± 6 dB and, if desired, can also be set synchronously with each other.

Price: € 2000,- The RESTEK MINT is a hi-fi integrated amplifier with analog signal preprocessing, a digital Class D output stage as the power core and an analog feedback with four inputs and a volume control that can be switched on and off. Many Class D amplifiers are designed for a specific load resistance of e.g. B. 4 ohms or 6 ohms optimized. If the load resistance deviates – and this is always different in terms of frequency in the case of loudspeakers – then frequency response differences of up to 6 dB result in particular at higher frequencies. Not so with the RESTEK MINT: Thanks to a sophisticated circuitry for analog feedback after the filter, the MINT integrated amplifier has a load-independent frequency response. No matter whether 2 Ohm, 8 Ohm or even 16 Ohm, the frequency response has a maximum deviation of 0.5 dB from 20 Hz to 20 kHz. That is why the RESTEK MINT lacks the analytical acuity that is often found. Rather, it always sounds analog, warm and full, without missing anything in terms of accuracy. The circuit concept with analog preprocessing, digital Class D amplifier core and analog feedback allows for the first time to bring an integrated amplifier onto the market that sounds “analog”.

Price: € 1450,- With the MPRE +, RESTEK has created the ideal preamplifier for the MAMP power amplifiers. It forms the control center in a hi-fi system composed of components from the M series. The preamplifier switches between the source devices and adjusts the volume of the music playback between these sources by amplifying or weakening its input sensitivity.

Another possible function, the interposition of different sound-changing filters, has been deliberately avoided in the MPRE +. Instead, the M-series preamplifier was completely bred for the highest possible reproduction quality and sound neutrality. Adaptation to the acoustic conditions of the listening room is only possible to a limited extent with the help of tone controls on the preamplifier. With high quality components, tone control is harmful rather than useful in most listening environments.

Price: € 700,- With the DC-coupled MINIPRE, RESTEK has created the ideal small preamplifier for music playback. He is the little brother of the MPRE + and forms the control center in a hi-fi system composed of components from the M series. The preamplifier switches between the source devices and adjusts the volume of the music playback between these sources by amplifying or weakening its input sensitivity. Another possible function, the interposition of different sound-changing filters, has been deliberately avoided in the MINIPRE. Instead, the M-series preamplifier was completely bred for the highest possible reproduction quality and sound neutrality. Adaptation to the acoustic conditions of the listening room is only possible to a limited extent with the help of tone controls on the preamplifier. With high quality components, tone control is harmful rather than useful in most listening environments. The “MINI” of the M series has four high-level inputs. The input sensitivity of the selected input can be adjusted within a range of +/- 6 dB to compensate for volume differences when switching between the individual inputs. Using the volume control, the signal can be attenuated by up to -95 dB or amplified by up to +10 dB.

Price / set: € 1400,- With the DC-coupled MAMP mono power amplifiers, RESTEK is providing its MPRE + preamplifier with the appropriate power amplifier from the M series. MPRE + and MAMP are not only optimally coordinated visually, but also technically. Together, the compact preamplifier MPRE + and the two equally compact mono power amplifiers MAMP form the amplifying core of a high-quality hi-fi chain trimmed to perfect musicality. The MAMP power amplifier has a mirror-symmetrical mono structure, divided into two compact housings. This structure leads to excellent values ​​for channel separation, channel equality and crosstalk. A moderate current and voltage negative feedback enables an optimal distortion distribution and thus also a “warm” analog sound with deep bass reproduction. At the same time, the MAMP power amplifier offers maximum operational reliability. A servo circuit regulates the offset voltage at the output to a minimum. The internal electronics are monitored with additional components for overtemperature, overcurrent and positive or negative offset voltage. In the event of a fault, the loudspeakers are separated from the electronics via a high-current relay.

Price /set: € 5100,- The increased quality of modern program sources also increases the demands on hi-fi amplifiers. A top-class mono power amplifier like the RESTEK EXTRACT not only meets these requirements in measurable peak data, but even more so in its tonal characteristics. The circuitry within the power stage is divided into four areas: The amplifier stages, i.e. voltage amplifiers (driver stage) and current amplifiers (output stage)
Operating and protection electronics to control and manage all functions.
Instrument and status displays to inform the user.
Power supply unit to power the entire device.
The amplifier stages must be designed for sufficient output power, which can mobilize sufficient power reserves at any time even under extreme load conditions. This ensures that the power amplifier is eliminated as a source of possible distortion even during large dynamic peaks. The tonal and metrological quality of the power amplifier is therefore consistently good within the designed performance range. The output stage works according to the parallel symmetrical principle and has a cascade connection in the input stage which controls eight end transistors via the driver stage. As a result, the RESTEK EXTRACT power amplifier is able to drive loudspeakers up to a minimum impedance of 2 ohms without any problems. It can deliver more than 400 watts.

Price / set: € 11800,- The RESTEK EXTENT amplifier uniquely combines a modern, timeless design with the latest amplifier technology and outstanding product quality. Like all devices from RESTEK, the EXTENT power amplifier was not only developed in Germany, but is also built entirely by hand in Germany. All components have been optimized for long durability and ease of servicing. The design is modern and timeless: with the exception of the on-off switch, all controls have been placed on the back of the amplifier. Two is always one plus one. This truism has a deeper meaning in amplifier technology: By separating the amplification power into two housings, one achieves several decisive advantages over integrated power amplifiers or integrated integrated amplifiers. Mono power amplifiers can be installed directly at the loudspeaker. The supply cables to the speakers can be extremely short. Electrical and acoustic losses are reduced to a minimum, which is particularly important with low-impedance loudspeakers.
Crosstalk between the two stereo channels is excluded when using mono power amplifiers. The spatial impression of the music is therefore fundamentally more perfect than when using integrated two-channel amplifiers.
