Amplifier from a specific level of quality would have to sound more or less the same, has a certain logic. Instead however, this utopian “point of the vanishing difference” come closer, it seems with increasing effort to remove more of it.
- Audionet Pre1 GS/EPS
- Data sheet
Many decades of collected hearing test experience teach one thing above all: the HiFi devices are easier and that compromise, the diffuser their tonal characteristics, to commit them will seem less, and they are harder to pull off. Conversely it surprised the tester little that the Audionet Pre1 G3 – preamplifier for taken already a very efficient, incorruptible clean and also comparatively inexpensive device – actually better sounded when you joined the charged additional power supply EPS.
From the EPS 24 volt come out, exactly same DC voltages so, with which also the integrated power supply of the Pre1 G3 labor whose amplifier stages. However they are processed generated with significantly larger transformers and much Low noise and more stable in the EPS, which weighs taken so much as a full-blown integrated amplifier, for themselves. Moreover, separates the Pre1 its internal toroidal transformer from the mains as soon as voltage is present on the EPS umbilical cord, and thus brings a source of electromagnetic interference to silence. Then only a small transformer which supplies the control logic of the Pre1G3 in the device remains active.
Just about anything is possible with dot matrix display, electronic volume signal box and relay input switches to comfort functions from the Bochum company consistently implemented: the Audionet precursor called connected devices by name (if you previously accordingly named the entrance), allows your own balance and level adjustment each input and switches for external surround sound processors on fixed level. Because the options menu directly lurks below the operating level, the owner gets and also opportunity to save visitors who wanted to change just the entrance, which have verfranzt then but hopelessly, with superior smile and a specific button.
Even the DC servo of preamplifier can be deactivated in the menu somewhere. Who is wary of the potential additional rule intervention in these assemblies and risked prefer something more DC voltage on the output of the preamplifier, can do so also this like. When using the Mono power amplifiers with the simple name “Amp”, even then no disaster risk grows from it if the connected sources when it comes to DC offset have a dubious reputation: In case of doubt, DC voltage monitor in the amps Flash take the whole unit from the power supply.
Openness and transparency are indeed impressive, especially with EPS support that not brighter but much clearer sound the Pre1. Also at the bottom of the transmission range, the German RC benefits from the afterburner power supply: that “powerful and unwavering” turns the daring assertion to the appropriate description.
