Our new flagship of the integrated amplifiers. The preamp section was completely new developed and benefits a lot of the SA-T7. Through the build-in Wifi modul the amplifier music streaming could be done and it could be integrated in your home network.
Our tubeLine is welcoming a new addition in the form of a hybrid integrated amplifier. What's new,
compared to our other models, is a WiFi and a Bluetooth port.
The SV-737 can be connected to the home network via the WiFi function, meaning it can support
streaming and, for example, play music files stored on a NAS.
In addition, the SV-737 sets new standards in terms of circuitry. The SV-737 is an integrated amplifier
with two amplifier sections – pre-amplifier and power amplifier – that have been matched perfectly to
one other. "Perfectly" here indicates that the combination of both amplifier characteristics ensures
maximum transparency and spectral stability for the audio output. Keywords for technicians here include
ear-friendly spectrum with k2 dominance in the typical dynamic range with regard to frequency and power.
Both amplifier sections are recent developments:
From the preamplifier SA-T7, the basic principle of two gain blocks with embedded, switchable tone
control has been adopted for the tube pre-amplifier. In contrast to the SV-237MK, an additional tube
system has been provided per channel, so that now two double triodes per channel with a total of
four systems are in use. The voltage amplification is provided by the 6N2P-EV manufactured according to military specifications, which has a characteristic curve that is similar to the well-known ECC83
or 12AX7 yet more linear. In addition, the 6N2P-EV is particularly low-microphone and low-noise.
With its high-current cathodes, the 6N1P takes over the function of the driver and buffer stage in the
proven manner. Also from the SA-T7, the proven regulation of the high voltage for the tube amplifier
has been adopted: A voltage reference tube 85A2, originally developed for professional measurement
technology, provides a low-noise and almost hum-free supply voltage in combination with a semiconductor regulator
