Overview
The HP 700 SE is a tube preamplifier that features innovative precision technology as well as sonic refinements to the output stage. Like its predecessor, the HP 700, it meets the listener’s individual wishes for their high-end combination thanks to its modular architecture.
Technology
In the new SE version, there are now two parallel XLR sockets next to the two RCA outputs on the back panel, allowing all types of bi-amping. But the modifications of the actual Class-A-output stage are even more important. The search for the even finer sound took place with the help of extremely time-consuming and complex measurements, along with accompanying listening sessions. These difficult adjustments are responsible for the tonal improvements, especially the mid-tone of the pre-amplifier. The tube configuration remains unchanged compared to the predecessor HP 700, as do all the other tried-and-tested technical refinements on this incomparable preamp.
External Power Supply
In combination with the newly developed, high-precision, low-noise supply-voltage stabilizing circuitry, the separate, magnetically shielded, outboard power supply of the HP 700 SE (essential for the low-noise and low-hum function of the MC-input) ensures constancy of the audio output even when the mains voltage is subject to wide fluctuations and high interference levels. Added to this, the integrated control logic system guarantees maximum operational reliability and, backed by our exclusive soft-start technologies, ensures the tubes and the unit have a life of up to twenty years.
Modular Design
The connection possibilities of the generously configured standard HP 700 SE model are rounded off by two user-selectable, optional input modules. An optimized input module can be used for unique applications, for anything from an MC step-up transformer to a transformer-based XLR input module. The plug and play modules can be readily installed or upgraded at any time. PHONO Innovative technology has also been applied in the redesign of the Phono RIAA amplifier. The further development of the RIAA stage has improved the signal/noise ratio, while simultaneously reducing system-related distortion. The widening of the bandwidth enables accurate RIAA equalization and exploits the full potential of analog reproduction. The wide variety of optional input modules ensures that the optimal input can be installed for any cartridge.
